Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public License instead of this License. freewheeling-0.6.6/ChangeLog000066400000000000000000001255131370736313100157540ustar00rootroot00000000000000 2019-05-02 v0.6.6 * fixed thread-count race condition during memory-manager init - long-standing bug which caused intermittent startup failures * changed C FALSE to C++ false in fluidsynth class - fixes build failures with GCC9 on some systems 2019-01-29 v0.6.5 * made compatible with both fluidsynth v1 and v2 * fixed deprecation and compiler warnings and other housekeeping tasks * removed experimental 'elastin' classes 2017-04-03 v0.6.4 * made font paths consistent with debian packaging * implemented 'tiny' font specified in graphics.xml (although still unused) 2017-04-01 v0.6.2 * FreeWheeling now requires nettle instead of gnutls-openssl because gnutls-openssl is no longer supported on ArchLinux * deprecation, bug, and compiler warning fixes by GitHub user 'Jajcus' 2016-10-31 v0.6.1 * new version control and repos - SVN history converted to git sadly, JP has been incommunicado for some time so it is not possible to properly maintain the sourceforge repo. the project has been forked to github and notabug for further development https://github.com/free-wheeling/freewheeling/ https://notabug.org/freewheeling/freewheeling/ * restored freewheeling wiki on github https://github.com/free-wheeling/freewheeling/wiki * upgraded autotools files * FreeWheeling will use semantic versioning from this point on (e.g. MAJOR.MINOR.REV) IN PROGRESS v0.6.1 - SVN Thursday March 17, 2011 * Multi-track streaming. Now you can stream each input to disk, stream loops to disk, and stream the whole final mix to disk. Control what to stream from basics.xml: This allows you to do more precise edits after a performance. It is especially useful for live microphone pickups, which often require separate gain and FX adjustments during later editing. As always, the disk streams can be toggled in real-time with the PrintScreen key (see help). Freewheeling finds an unused filename for each new stream. The streams are time-aligned, so they can be loaded as tracks into a multi-track sequencer. Thursday March 10, 2011 * Configurable soft monitoring is now available in basics.xml: * QTractor OSC integration is now working. Saturday February 26, 2011 After more than two years, activity has resumed on Freewheeling's development. I am in the process of refactoring the code to make it more stable. New Features in the works: * DONE - Direct hardware mixing controls Direct control of ALSA mixer controls from within Freewheeling * DONE - SYNTHEDIT - An easier way to manage synth plugins with MANY parameters from a tactile interface with FEW knobs - stores parameters and allows motor-fader updates * FIXED - MIDI Sync Transmit now works as advertised - Loops stay in lockstep with externals Added MIDI sync metronome for listening to beats/bars. * QTractor integration. Rui Nuno Capela and I are working on a QTractor branch that will allow snapshots of all playing loops to be instantly transferred into a QTractor session. Go from circular time to sequencer time! This SVN update contains proof-of-concept code against the 'qtractor-osc' branch. Tuesday January 20th, 2009 New Features ------------ * A proper BCF-2000 Preset (SYSEX Dump Format) is now included See data/bcf2000-help.txt for instructions if you use a BCF-2000. * Snapshot moving ALT-P swaps the last two selected snapshots. * Z/X paging through loops now works across interfaces (BCF-2000, MIDI keyboard, ...) Sunday December 28th, 2008 New Features ------------ * As part of ongoing work to make Freewheeling more reliable, crash reports are now automatically generated if GDB is installed. The type of crash is printed on the terminal. The report is saved to file 'fweelin-stackdump'. If you encounter a crash, please send me this file along with a description of what you were doing when the crash occurred. Thank you. Fixes ----- * Fixed an overdub crash with the new triggering method * Fixed a positioning bug when recording loops with the new triggering method Friday December 25th, 2008 New Features ------------ * This version uses an experimental new way of triggering loops. The loops always play immediately when triggered, and they start in the right place. The 'right place' is given by a 'long count', which is the overall pattern of all loops. This method allows switching between snapshots mid-phrase without a loss of positioning, and triggering new snapshots before the downbeat to catch pickup notes. Musically, the long count is the length of the larger musical phrase which is described by all the loops. Mathematically, the long count's length is the LCM (Lowest Common Multiple) of the length of all loops that have been activated. (Example) For a scene with loops with length 1, 2, 4, and 8 beats, the long count is 8 beats. For a scene with loops length 4 and 3 beats, the long count is 12 beats. You don't really have to think about the long count. But it's helpful to know that the long count is defined so that when it rolls over, all loops are rolling over to their start points. You can see the long count visually in an outer ring of the pulse display (top right). The old triggering method is no longer in this version. I would appreciate any feedback you might have on how this new method works for you. Happy Holidays! -Mercury Tuesday October 28th, 2008 New Features ------------ * Automatic bypassing of unused channels now works with combi patches across many zones Sunday October 19th, 2008 New Features ------------ * Improved MIDI handling with automatic bypassing of unused channels This new feature keeps track of which patches are active and recently used, and which have sustaining notes either with or without pedal. FreeWheeling will automatically send out a configurable MIDI CC on those channels that are inactive, and another CC when those channels become active. As I'm playing, FreeWheeling automatically frees up CPU from unused plugin channels on my plugin hardware rack. You can use this feature with any plugin host that will bypass/unbypass channels via MIDI CC. I use it with a Muse Research Receptor. ** Patch changes are now registered when you SELECT a patch. Browsing to the patch does not switch patches. Now, you must move to the new patch and press ENTER or a MIDI select button. For example, the following in a patch definition file: Defines a piano patch sending on channel 0 (1st MIDI channel). After 60 seconds of unreleased sustained notes, when the channel is inactive, it will be bypassed. 5 seconds after all notes are released with the sustain pedal up, and once the channel is inactive, it will be bypassed. This follows the natural decay of a piano- long sustain, short release. I can play piano notes, hold them, and switch to another channel. When I release those piano notes, the appropriate notes are released and the channel is bypassed soon after. I am already continuing on with whatever new patch I'm playing. Here, two drum patches that receive on channel 10 and 11 are defined. They are both bypassed via channel 5. I use this with multitimbral plugins that receive on several channels but are bypassed as one. To enable auto-bypass, you must define a MIDI CC to use. This can be defined for each patch or combi zone, but is more easily defined for a whole patchbank (from browsers.xml): Here MIDI CC #116 is used to auto-bypass channels on the Receptor. You can also set default values for bypasstime1 and bypasstime2 on a per-patchbank basis. Fixes ----- * Fixed doubling of MIDI note-off messages RELEASE v0.6 Friday October 3rd, 2008 Folks, Here is a full 0.6 release. Included are updated Mac and Linux versions. The new Mac version works with the latest Jack version and under OS X Leopard. As you can see from the SVN updates below, there's quite a bit that's new since 0.5.5. Your feedback is always welcome. -~Mercury v0.5.6 - SVN Thursday September 4th, 2008 New Features ------------ * Logarithmic faders and loop levels, conforming to IEC 60-268-18. Level meters and loop faders are now logarithmic, visually graded with 6dB markings. This means you can create much smoother fades using MIDI controllers, and you can see a broader range of levels on-screen. One new configuration parameter controls the maximum dB selectable: Saturday August 30th, 2008 Fixes ----- * Saving over existing snapshots now preserves name * Upgrades to BCF-2000 template Wednesday August 13th, 2008 New Features ------------ * Rename snapshots Press ALT-1 through ALT-9 to rename a snapshot. Label your song sections for easy recall. * Way overhauled BCF-2000 interface The Behringer BCF-2000 MIDI template has been overhauled. Most major functions can be controlled from the surface. Continuously variable loop volumes, overdubs on knob presses, loop selection and triggering, scenes, pulses, and multiple pages of loops. The whole template can be customized by editing the MIDI CC variables at the top of the file. By changing the CCs, you can use it as a template for other control surfaces. A future configuration editor may build on this concept of 'templates with editable settings'. For now, you can edit the file and adjust the most common commands easily. Saturday July 5th, 2008 New Features ------------ * Multiple pages of snapshots 100 snapshots are provided by default (edit this in basics.xml). You can pageup/pagedown through them by holding CTRL or SHIFT and pressing , or . Then use CTRL 1-9 to trigger and SHIFT 1-9 to store. Fixes ----- * Reworked some of the guts to fix crashes. Race condition fixes in block manager. Thanks to Florent and Andrea for your crash reports. They helped nail the bug. Monday Jun 16th, 2008 New Features ------------ * Create snapshots for playing loops - Create / save / load snapshots. All loop levels and playing loops are remembered. To create a snapshot, hold SHIFT and press 1-9. The snapshot is shown in a popup window. - An easy way to switch between song sections. To switch snapshots, hold CTRL and press 1-9. - Snapshots are saved/loaded in scenes. Still to do on snapshots: Renaming, fading, paging through snapshots on display, more flexible synchronization. * Easily adjust levels for all selected loops To use: Select some loops. Hold CTRL and press UP/DOWN repeatedly to adjust all loop levels. Or, hold CTRL and use the mousewheel on any loop. All selected loops are adjusted. This works well when you have many loops that are overdriving Freewheeling's outputs. The limiter is bouncing around. You could reduce the output level, but this approach is more flexible- and the results are saved in snapshots and scenes. Friday Nov 9th, 2007 New Features ------------ * Completely revamped configuration system- Better splitting and organization- There are now many configuration files. The configuration is divided into 'interfaces'. Each interface defines behavior and display related to a hardware interface. You can build whole functionality for a given MIDI interface such as a fader box, and share it on the Internet. This should help the current situation where people are patching together bits of each other's configurations. Sunday July 8th, 2007 New Features ------------ * Working on real-time pitch and time stretching- not yet usable! * Adjustable global tuning for Fluidsynth: From .fweelin.rc: Adjusts Fluidsynth to -31.76 cents tuning, or 432 Hz tuning. Fixes ----- * Fixed a bug where some non-critical events (such as loading or selecting loops) could be missed. * Fixed glitch in memory manager that could cause spontaneous exits, usually when erasing loops * Better clipping of out-of-range MIDI values * Removed old 'DelayProcess' code for dealing with real-time events. New code uses real-time event manager. Tuesday March 13th, 2007 New Features ------------ * Erase-selected-loops command Shift+Space now erases all selected loops. * New ability to tag patch banks By tagging patch banks, you can change the way Freewheeling responds depending on which patches you have selected. For example, I use Freewheeling with a B3 organ softsynth. My organ patches are arranged in a patch bank. I've tagged that patch bank, and configured Freewheeling to respond differently when that patch bank is active. So, when I am on an organ patch, my faders control the B3 drawbars instead of their usual Freewheeling functions. You can, of course, change any of Freewheeling's behaviors depending on the patch bank selected. For more info, check the 'SYSTEM_cur_patchbank_tag' variable in the configuration. * Receive and transmit MIDI channel pressure (aftertouch) messages * New 'routethroughpatch' configuration option for MIDI events allows you to send deliberate MIDI messages to the port(s) and channel(s) for the current patch. An example configuration is provided that changes the behavior of the modwheel (CC #1). When enabled, the modwheel value is modulated by aftertouch. This allows me to control vibrato (CC #1) on my softsynths with pressure on the keys. The modwheel and pressure values are summed together and sent out as a control change message. If I am playing several softsynth channels from my one keyboard, the aftertouch then affects all the channels seamlessly. Fixes ----- * Fixed problem installing configuration files from folders with spaces. 2007-01-25 v0.5.5 New Features ------------ * MIDI sync transmit - Toggle-able sync transmit on definable output ports A friend of mine who is an avid Ableton Live user asked me to collaborate with him. I realized that this was a perfect opportunity to develop MIDI sync. Freewheeling already syncs via the Jack transport, but Ableton and other hardware sequencers are not Jack-aware. As of this version, Freewheeling transmits MIDI sync on definable MIDI outs. By default, MIDI clock is sent to the first MIDI output. To send MIDI clock, you must first enable it-- Go to the sync panel (shift+F1) and press shift+F2. MIDI Sync Transmit is now enabled (the light glows). Now, you can begin playing, and create a pulse. You can either tap the pulse tempo, or you can record a loop and use it as the pulse tempo. Once the pulse begins, Freewheeling starts the external sequencer at bar 1. If you deselect the pulse (F6 for free timing), Freewheeling will stop your external sequencer. Any pulse you select will begin transmitting MIDI sync. Freewheeling does not yet receive MIDI sync, so you can't yet use Ableton as tempo master. * Selecting and working with multiple loops You can now toggle (t) and fade (MIDI CC89) volume of several loops together. You can select loops by right clicking on them, or by shift+clicking on them, or by shift+pressing their trigger. You can select all playing loops by pressing the keypad asterisk. You can select all idle loops with shift+kp asterisk. Ctrl+kp asterisk inverts the current selection, and alt+kp asterisk unselects all loops. This is the first step towards having multiple scenes of loops that you can trigger/fade between. * New configuration allows MIDI control of: Undo- CC#51 Patch bank changing by fader- CC #88 Patch bank changing by buttons- CC #53 / #54 * Continuously variable feedback for overdubs You can now change the loop feedback during overdubbing. You can realtime vary the amount of the loop that is fed-back into itself. The current feedback level is shown on-screen. By default, MIDI CC#87 controls the loop feedback. The feedback controls are configurable in .fweelin.rc, here: * New configuration allows browsing via MIDI program change I developed this config for the CME-UF8 master controller, which has a rotary encoder that sends MIDI program change messages. With the new config, a MIDI program change knob can be used to spin through scenes, loops, or softsynth patches. Also, controller #50 is configured to act as a shift key for faster scrolling through browsers. * Save Current Scene (F7) now overwrites an existing scene. * Save New Scene (shift + F7) forces a new scene to be created. When overwriting, sequential backups are made with the extensions '.backup.1' '.backup.2' etc. Scene file data is very small. Loops are stored separately, so there is no duplication of unmodified loops. * Sync panel can now be toggled with Shift-F1 Defaults to OFF Fixes ----- - Better stability in Event Manager- should fix crashes - Deliberate MIDI output of events now follows the ports and channels you specify. Incidental echoing of MIDI events follows the settings from the current patch. - Fixed crash on repeat loading of scenes/loading of large scenes - No more console-dependent startup questions when a new version is installed. - Library path can now be specified relative to home folder (for example, ~/fw-lib) - Stream out now shows size in mb, for less frantic update 2006-11-21 v0.5.3 Many thanks to Danni Coy, who has contributed very significantly to this release. Actually, he did most of the work! New Features ------------ * MAC OS X support FreeWheeling is now cross-platform. A universal binary is now available for both Intel & PPC Mac platforms. * Multiple Audio Formats (Contributed by Danni- Thank You!) Save and load loops and live streams in OGG, WAVE, AU, and FLAC. * OGG encoding quality setting in configuration * More flexible MIDI control of external synths. - Combination patches allow you to split one MIDI controller into a range of zones. This allows you to control several different sounds or softsynths from one MIDI control source. A combipatch defines the zones, as well as the output MIDI port and channel that each zone sends to. You can also send MIDI program and bank change messages for each zone, allowing you to switch programs on external synths. All of this functionality is integrated into the patch browser, so you can seamlessly control other synth apps and sound modules from within FreeWheeling. See 'examples/combipatchdemo.xml' for an example configuration. - Added 'suppressprogramchanges' option for patch banks With suppressprogramchanges=1, no MIDI bank and program change messages are sent when patches are changed within a patch bank. This is useful when you have a softsynth loaded with patches on different channels and you merely want to switch channels- each patch is mapped to a different channel, but you don't want program change messages being sent to mess up your patches. Use this for banks of Linuxsampler channels. - Added 'separatechannels' option for patch banks With separatechannels=0, patches mapped to different channels appear in the same patch bank. With this option, you can have a collection of several patches on different channels that appear together in one list for browsing. This is useful for sampling synths where your patches are pre-loaded onto channels. With separatechannels=1, the old behavior is used. The old behavior splits each channel into a separate bank. This works well for DSSI softsynths, where many synths run on the same port, but each channel accesses a different synth and different set of patches. Fixes ----- * MIDI thread now runs at high priority FIFO, rather than low priority FIFO-- this may improve MIDI performance, and hopefully will not affect stability. * Fixed configuration bug that broke 'CTRL+click' loop renaming. 2006-05-17 v0.5.2a Bug Fix Release --------------- * v0.5.2 MIDI port switching was broken. (Problem in the configuration .fweelin.rc). The configuration in this release should work. No other changes have been made. 2006-05-13 v0.5.2 The Patch Browser Upgrade New Features ------------ * Integrated patch browsers for external audio apps * Bank and program changes are now sent based on the patches you define * MIDI outputs are now switched as part of the integrated patch browser * Automatic patch list generation for DSSI softsynths Detail: The Fluidsynth patch browser has been expanded to provide patch browsing for external synths/apps. You can define your patches (MIDI port, channel, bank, program, and name) in external XML patch files. All your patches, internal and external, now appear in the patch browser. The browser now has several pages, one for each MIDI port and channel for which you have defined patches. Therefore, if you have Hexter on channel 1 of MIDI output 1, and WhySynth on channel 2 of MIDI output 1, you can independently browse your Hexter and WhySynth patches right from within Freewheeling. Freewheeling sends the right bank and program changes out the right MIDI port based on your patch definitions. It also echoes your MIDI events to the right place, so that you can switch one keyboard between several softsynths. When you have the patch browser selected, you can use the left/right arrow keys to switch between browser sections. This causes your incoming MIDI events to be switched from one port to another- as defined in your ~/.fweelin.rc and patch XML files. This way, you can quickly switch between softsynths without leaving Freewheeling's interface. To use this feature, please read 'examples/readme.txt' for setup info. I will likely be expanding this to include 'combi' type actions where you can custom configure your MIDI signal to be sent to several softsynths. Then you could, for example, play Hexter with your left hand and Linuxsampler with your right hand. * Configuration files now live in ~/.fweelin/ ~/.fweelin.rc will be moved to ~/.fweelin/.fweelin.rc when you start version 0.5.2. Fixes ----- * Fixed startup segfault when running without integrated FluidSynth 2006-03-22 v0.5.1 Thank you to all for good ideas and inspiration over the summer and winter. Many thanks to Paul Davis for hooking me up with a great Linux Audio development gig. And thanks to an anonymous donor for his contribution, and to Dubphil and Paul Brossier for beta testing. ** FreeWheeling now requires libgnutls11-dev (gnutls-openssl) instead of openssl (Thanks, Piem). New Features ------------ * Significantly less memory usage-- more than 20 megabytes less. Thanks to Drobilla for pointing out the issue with thread stack size. * New scripts (see scripts/ folder) to help you manage a library of loops. You can now bath move, delete, and archive loops & scenes by date. * Jack transport sync- - Master and slave mode For sync to work, you must first create a pulse, either by recording a loop and pressing F1, or by tapping a pulse by tapping F2 twice. Freewheeling tries to become the Jack timebase master, but if another app is master, it switches to slave mode. In master mode, Freewheeling generates beats and bar counts for every repetition of the currently selected pulse. In slave mode, Freewheeling receives beats and bar counts and syncronizes the currently selected pulse to them. For both master and slave modes, you can adjust the number of bars/beats per pulse using: Ctrl/Shift + S - adjust timebase You can also switch between sync to bars or sync to beats using: Alt + S - switch bars/beats sync Note that in master mode, FW is currently hard-wired to generate 4 beats per bar. Since this is preliminary code, not a big deal. * New user interface - Progress bar for saving and loading loops and scenes - Better organization of help page with clear sections - Mouse support - Click on loops triggers them. - Space + Click erases loops. - Mousewheel on loops now adjusts loop volumes-- very convenient when you are mixing and playing with improvisations. These can be configured. See 'loop-clicked' in .fweelin.rc. - Joystick support - Joystick buttons can now trigger events. For example, I have used FW with a DDR dance mat to trigger loops. See 'joybutton' in .fweelin.rc. - New 'engage' and 'shot' options in trigger-loop. 'Engage' forces a loop to ON or OFF, overriding the default toggle behavior. You can use it to create triggers that play short bursts, rather than long loops. 'Shot' to be implemented. * Stability improvements - Better thread safety and design improvements to the real-time memory manager have improved stability. * Significant improvements to loop/scene management and browsing - You can now give loops and scenes your own names - New names are stored within the filename of library files - Expanded browser window shows several items at once - Browser now sorts so that newer loops and scenes are first * Better handling of looppoints - Resolved issue with clicking at the looppoint on reloaded loops. - Resolved sporadic clicks on syncronized loops. * Better handling of loading/saving loops * Adjustable video loop delay - You can now adjust the performance of FreeWheeling by changing the delay between video refreshes. Several people asked for this feature, because FW is processor-heavy on the video side. The video thread does run at a low priority, and so it should not affect the performance of other realtime audio threads. However, the system may get sluggish, and if this happens, you may want to increase the delay in .fweelin.rc: Fixes ----- * Fixed 'glibc double free' segfault- FW should now run when compiled with GCC 4.0. * Adjusted the way F2 tap tempo works- tapping a new tempo with F2 is now more responsive, but less tolerant of mistakes * Fixed 'pure virtual method called' segfault * Fixed segfault when browsing past end of FluidSynth patch list * Various fixes to reduce CPU hogging * Merged patches from Piem's debian package: MaxVol, compile fixes for GCC 4.0, and removal of non-free elements * FW can now run without physical JACK inputs or outputs. Thanks to Piem for this patch. 2005-05-02 v0.5pre4 Many thanks to Sune Mai for several clever fixes, to Plutek for your generous donation, and to all of you for inspiration and feedback: Wolfgang Woehl, Mark Knecht, Shayne O'Connor, Esben Stien, Gregory Maxwell... ** FreeWheeling now requires libvorbisfile. New Features ------------ * Go back to previous improvisations - Saving -and- loading of loops and scenes of many loops - Integrated browser for scenes, loops, and FluidSynth patches - Loops and scenes are sorted by time in browser QuickStart: Use F8 to save a loop, F7 to save a scene of all loops, F9 to toggle auto-saving of all loops, 'b' to switch browsers from FluidSynth to Loops to Scenes, 'enter' to load the selected loop or scene, Shift +/- jumps to the next group of scenes or loops on disk (at least an hour different in time) When loading a scene, the loops are restored to their original placement. When loading a single loop, it goes to the footswitch (SW) by default. You can then move it to any QWERTY or MIDI key by pressing that key. FreeWheeling no longer saves in folders save1, save2, etc. A new library folder (by default, fw-lib/) contains all your loops, scenes, and live mixes. A new script scripts/godelete-date, can be used to delete loops and scenes from your library by date. * Full stereo support - Individual inputs configurable stereo or mono - Automatic stereo or mono loops - FluidSynth in stereo or mono QuickStart: In ~/.fweelin.rc find: This configures two mono and one stereo input. FreeWheeling no longer auto-connects to system inputs and outputs. You only need to configure what kinds of inputs you'd like. Please note that, for now, you need to manually add displays and keyboard mappings for any inputs you add. The rest is handled automatically. * Multiple ALSA MIDI outputs - Send live MIDI messages to different MIDI ports to control different Linux apps in real-time QuickStart: Use "m" key to switch MIDI outputs. The default configuration, defines two MIDI outputs. "m" toggles between the two outputs and the internal FluidSynth. * Configurable limiter - Max gain, threshold, and release rate can be changed - By default, limiter no longer raises gain above 100% See help in ~/.fweelin.rc * Input level displays - Peak levels for each input are now shown * Footpedal volume adjust configuration QuickStart: Use MIDI controller 1 to control individual input levels. Press keyboard 1-4 to select input. Then move CC1 to adjust volume. Or press and hold keyboard 1-4 while moving CC1 to jump to a new pedal value without adjusting volume. In ~/.fweelin.rc, see: You can change the CC# and max volume. * Laptop keyboard configuration QuickStart: If you are using FW on a laptop, you probably don't have easy access to some keys. I've provided a laptop keyboard configuration which remaps some keys. In the help pages, the new keys are shown in square brackets. To enable this configuration, edit ~/.fweelin.rc: init="0" becomes init="1" * Config file version checking - If your config file is out of date, FreeWheeling will ask whether you'd like a new one installed. This means you never have to manually erase ~/.fweelin.rc. Fixes ----- * fixed MIDI note off being misinterpreted on keyboards that send note on with velocity 0 * JACK ports are no longer auto-connected * fixed startup hang on some systems (mutex init problem) * fixed bug in block memory allocator Recycle() that causes a segfault during bursting of many events * compile fix error: 'ISO C++ forbids cast to non-reference type used as l-value' in RTNew() * footswitch is now controller 64 by default, not 67 * several keys have been remapped- see the help for details 2005-03-11 v0.5pre3 New Features ------------ * A new way to tap downbeat and tempo (tap-pulse event) * Switching of metronome sound for pulses (switch-metronome event) * FreeWheeling events can now trigger MIDI events, so you can control other audio apps from within FluidSynth-- For example, you can fire off changes to your modular synths from your keyboard or footpedals. This eliminates the need for an extra MIDI router app, since it is now built in to FreeWheeling. Your custom FreeWheeling setup defines how MIDI events are generated. * More flexible, clearer configuration syntax, with better error checking and colored warning messages. * Full input & output implementation of MIDI program change and pitch bend messages. * An example of the new MIDI output features- A MIDI patch changer has been configured using the left/right arrow keys. An on screen display shows patch number. See .fweelin.rc and video tutorial: Hookups. * Faster, tighter memory management for events. * Scripts are now included that load FreeWheeling and Hexter DX7 softsynth, connect to LADSPA reverb and tube amp sim- see scripts/README. Fixes ----- * fixed config bug that may cause "PreallocatedType: no instance available" errors on startup * compile fix on Mandrake GCC 3.4.x - 'parenthesized type-id' error 2005-01-19 v0.5pre2 New Features * Saving and autosaving of loops in OGG format- loops and live mixes are saved in their own folders * Real-time toggling of FluidSynth * Multipage help * Documentation for 'z'/'x' loop octave Fixes * configure check for SDL_gfx filledPieRGBA vs filledpieRGBA * configure now gives websites for dependent libraries * added XInitThreads to fix 'Xlib async reply' error 2005-01-03 v0.5pre1 - first public prerelease 2003 -2004 v0.1, 0.2, 0.3, 0.4 (internal) many internal changes-- * moving from OpenGL to 2-D SDL * loop visuals * downbeat awareness * memory manager * event manager * block extended data * configuration system * many bugfixes These form the foundation of FreeWheeling as a modular looping platform. 2002-06-05 FreeWheeling (then 'dogon listening device') * initial Linux version based on Mac MAX/MSP prototype freewheeling-0.6.6/INSTALL000066400000000000000000000366141370736313100152360ustar00rootroot00000000000000Installation Instructions ************************* Copyright (C) 1994-1996, 1999-2002, 2004-2016 Free Software Foundation, Inc. Copying and distribution of this file, with or without modification, are permitted in any medium without royalty provided the copyright notice and this notice are preserved. This file is offered as-is, without warranty of any kind. Basic Installation ================== Briefly, the shell command './configure && make && make install' should configure, build, and install this package. The following more-detailed instructions are generic; see the 'README' file for instructions specific to this package. Some packages provide this 'INSTALL' file but do not implement all of the features documented below. The lack of an optional feature in a given package is not necessarily a bug. More recommendations for GNU packages can be found in *note Makefile Conventions: (standards)Makefile Conventions. The 'configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a 'Makefile' in each directory of the package. It may also create one or more '.h' files containing system-dependent definitions. Finally, it creates a shell script 'config.status' that you can run in the future to recreate the current configuration, and a file 'config.log' containing compiler output (useful mainly for debugging 'configure'). It can also use an optional file (typically called 'config.cache' and enabled with '--cache-file=config.cache' or simply '-C') that saves the results of its tests to speed up reconfiguring. Caching is disabled by default to prevent problems with accidental use of stale cache files. If you need to do unusual things to compile the package, please try to figure out how 'configure' could check whether to do them, and mail diffs or instructions to the address given in the 'README' so they can be considered for the next release. If you are using the cache, and at some point 'config.cache' contains results you don't want to keep, you may remove or edit it. The file 'configure.ac' (or 'configure.in') is used to create 'configure' by a program called 'autoconf'. You need 'configure.ac' if you want to change it or regenerate 'configure' using a newer version of 'autoconf'. The simplest way to compile this package is: 1. 'cd' to the directory containing the package's source code and type './configure' to configure the package for your system. Running 'configure' might take a while. While running, it prints some messages telling which features it is checking for. 2. Type 'make' to compile the package. 3. Optionally, type 'make check' to run any self-tests that come with the package, generally using the just-built uninstalled binaries. 4. Type 'make install' to install the programs and any data files and documentation. When installing into a prefix owned by root, it is recommended that the package be configured and built as a regular user, and only the 'make install' phase executed with root privileges. 5. Optionally, type 'make installcheck' to repeat any self-tests, but this time using the binaries in their final installed location. This target does not install anything. Running this target as a regular user, particularly if the prior 'make install' required root privileges, verifies that the installation completed correctly. 6. You can remove the program binaries and object files from the source code directory by typing 'make clean'. To also remove the files that 'configure' created (so you can compile the package for a different kind of computer), type 'make distclean'. There is also a 'make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. 7. Often, you can also type 'make uninstall' to remove the installed files again. In practice, not all packages have tested that uninstallation works correctly, even though it is required by the GNU Coding Standards. 8. Some packages, particularly those that use Automake, provide 'make distcheck', which can by used by developers to test that all other targets like 'make install' and 'make uninstall' work correctly. This target is generally not run by end users. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the 'configure' script does not know about. Run './configure --help' for details on some of the pertinent environment variables. You can give 'configure' initial values for configuration parameters by setting variables in the command line or in the environment. Here is an example: ./configure CC=c99 CFLAGS=-g LIBS=-lposix *Note Defining Variables::, for more details. Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you can use GNU 'make'. 'cd' to the directory where you want the object files and executables to go and run the 'configure' script. 'configure' automatically checks for the source code in the directory that 'configure' is in and in '..'. This is known as a "VPATH" build. With a non-GNU 'make', it is safer to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use 'make distclean' before reconfiguring for another architecture. On MacOS X 10.5 and later systems, you can create libraries and executables that work on multiple system types--known as "fat" or "universal" binaries--by specifying multiple '-arch' options to the compiler but only a single '-arch' option to the preprocessor. Like this: ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CPP="gcc -E" CXXCPP="g++ -E" This is not guaranteed to produce working output in all cases, you may have to build one architecture at a time and combine the results using the 'lipo' tool if you have problems. Installation Names ================== By default, 'make install' installs the package's commands under '/usr/local/bin', include files under '/usr/local/include', etc. You can specify an installation prefix other than '/usr/local' by giving 'configure' the option '--prefix=PREFIX', where PREFIX must be an absolute file name. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you pass the option '--exec-prefix=PREFIX' to 'configure', the package uses PREFIX as the prefix for installing programs and libraries. Documentation and other data files still use the regular prefix. In addition, if you use an unusual directory layout you can give options like '--bindir=DIR' to specify different values for particular kinds of files. Run 'configure --help' for a list of the directories you can set and what kinds of files go in them. In general, the default for these options is expressed in terms of '${prefix}', so that specifying just '--prefix' will affect all of the other directory specifications that were not explicitly provided. The most portable way to affect installation locations is to pass the correct locations to 'configure'; however, many packages provide one or both of the following shortcuts of passing variable assignments to the 'make install' command line to change installation locations without having to reconfigure or recompile. The first method involves providing an override variable for each affected directory. For example, 'make install prefix=/alternate/directory' will choose an alternate location for all directory configuration variables that were expressed in terms of '${prefix}'. Any directories that were specified during 'configure', but not in terms of '${prefix}', must each be overridden at install time for the entire installation to be relocated. The approach of makefile variable overrides for each directory variable is required by the GNU Coding Standards, and ideally causes no recompilation. However, some platforms have known limitations with the semantics of shared libraries that end up requiring recompilation when using this method, particularly noticeable in packages that use GNU Libtool. The second method involves providing the 'DESTDIR' variable. For example, 'make install DESTDIR=/alternate/directory' will prepend '/alternate/directory' before all installation names. The approach of 'DESTDIR' overrides is not required by the GNU Coding Standards, and does not work on platforms that have drive letters. On the other hand, it does better at avoiding recompilation issues, and works well even when some directory options were not specified in terms of '${prefix}' at 'configure' time. Optional Features ================= If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving 'configure' the option '--program-prefix=PREFIX' or '--program-suffix=SUFFIX'. Some packages pay attention to '--enable-FEATURE' options to 'configure', where FEATURE indicates an optional part of the package. They may also pay attention to '--with-PACKAGE' options, where PACKAGE is something like 'gnu-as' or 'x' (for the X Window System). The 'README' should mention any '--enable-' and '--with-' options that the package recognizes. For packages that use the X Window System, 'configure' can usually find the X include and library files automatically, but if it doesn't, you can use the 'configure' options '--x-includes=DIR' and '--x-libraries=DIR' to specify their locations. Some packages offer the ability to configure how verbose the execution of 'make' will be. For these packages, running './configure --enable-silent-rules' sets the default to minimal output, which can be overridden with 'make V=1'; while running './configure --disable-silent-rules' sets the default to verbose, which can be overridden with 'make V=0'. Particular systems ================== On HP-UX, the default C compiler is not ANSI C compatible. If GNU CC is not installed, it is recommended to use the following options in order to use an ANSI C compiler: ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" and if that doesn't work, install pre-built binaries of GCC for HP-UX. HP-UX 'make' updates targets which have the same time stamps as their prerequisites, which makes it generally unusable when shipped generated files such as 'configure' are involved. Use GNU 'make' instead. On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot parse its '' header file. The option '-nodtk' can be used as a workaround. If GNU CC is not installed, it is therefore recommended to try ./configure CC="cc" and if that doesn't work, try ./configure CC="cc -nodtk" On Solaris, don't put '/usr/ucb' early in your 'PATH'. This directory contains several dysfunctional programs; working variants of these programs are available in '/usr/bin'. So, if you need '/usr/ucb' in your 'PATH', put it _after_ '/usr/bin'. On Haiku, software installed for all users goes in '/boot/common', not '/usr/local'. It is recommended to use the following options: ./configure --prefix=/boot/common Specifying the System Type ========================== There may be some features 'configure' cannot figure out automatically, but needs to determine by the type of machine the package will run on. Usually, assuming the package is built to be run on the _same_ architectures, 'configure' can figure that out, but if it prints a message saying it cannot guess the machine type, give it the '--build=TYPE' option. TYPE can either be a short name for the system type, such as 'sun4', or a canonical name which has the form: CPU-COMPANY-SYSTEM where SYSTEM can have one of these forms: OS KERNEL-OS See the file 'config.sub' for the possible values of each field. If 'config.sub' isn't included in this package, then this package doesn't need to know the machine type. If you are _building_ compiler tools for cross-compiling, you should use the option '--target=TYPE' to select the type of system they will produce code for. If you want to _use_ a cross compiler, that generates code for a platform different from the build platform, you should specify the "host" platform (i.e., that on which the generated programs will eventually be run) with '--host=TYPE'. Sharing Defaults ================ If you want to set default values for 'configure' scripts to share, you can create a site shell script called 'config.site' that gives default values for variables like 'CC', 'cache_file', and 'prefix'. 'configure' looks for 'PREFIX/share/config.site' if it exists, then 'PREFIX/etc/config.site' if it exists. Or, you can set the 'CONFIG_SITE' environment variable to the location of the site script. A warning: not all 'configure' scripts look for a site script. Defining Variables ================== Variables not defined in a site shell script can be set in the environment passed to 'configure'. However, some packages may run configure again during the build, and the customized values of these variables may be lost. In order to avoid this problem, you should set them in the 'configure' command line, using 'VAR=value'. For example: ./configure CC=/usr/local2/bin/gcc causes the specified 'gcc' to be used as the C compiler (unless it is overridden in the site shell script). Unfortunately, this technique does not work for 'CONFIG_SHELL' due to an Autoconf limitation. Until the limitation is lifted, you can use this workaround: CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash 'configure' Invocation ====================== 'configure' recognizes the following options to control how it operates. '--help' '-h' Print a summary of all of the options to 'configure', and exit. '--help=short' '--help=recursive' Print a summary of the options unique to this package's 'configure', and exit. The 'short' variant lists options used only in the top level, while the 'recursive' variant lists options also present in any nested packages. '--version' '-V' Print the version of Autoconf used to generate the 'configure' script, and exit. '--cache-file=FILE' Enable the cache: use and save the results of the tests in FILE, traditionally 'config.cache'. FILE defaults to '/dev/null' to disable caching. '--config-cache' '-C' Alias for '--cache-file=config.cache'. '--quiet' '--silent' '-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to '/dev/null' (any error messages will still be shown). '--srcdir=DIR' Look for the package's source code in directory DIR. Usually 'configure' can determine that directory automatically.

A Universal binary will be made available for each release, along with source code if you wish to compile it yourself. The user interface remains the same across OS X and Linux versions. This means that FreeWheeling OS X does not make use of Mac's Aqua interface. A few basic commands specific to the Mac version have been provided in a Mac menu. The rest of the functionality is built into the app window. FreeWheeling is designed to be mostly MIDI and keyboard driven. A few things can be done from a mouse, but while playing music, the idea is to keep your hands on your instrument. FreeWheeling is not a music production or DJing tool. FreeWheeling works for instrumentalists, such as drummers, guitarists, keyboardists and vocalists. FreeWheeling is like a second instrument, that you use to reflect back parts of your playing, to build loops in a spontaneous way. You can configure FreeWheeling to work with the PC keyboard, joysticks, or MIDI-enabled devices. Setup for Mac OS X ================== 1. Drag the 'Fweelin' app to the 'Applications' folder. 2. Download and install JACK. http://jackosx.com/ Jack is an audio connection kit similar to Rewire. It allows you to plug FreeWheeling into different audio apps, such as soft synths or sequencers. 3. Start 'Jack Pilot', included with your JACK installation. Set the lowest possible latency that provides stable performance. Set 'Jack Pilot' to 'Full Duplex' (recording and playback enabled), if you wish to record live instruments in FreeWheeling. If you are using the onboard Mac sound, you can get 'Full Duplex' recording and playback by creating an 'Aggregate Audio Device'. To do this, choose 'Open Audio MIDI Setup' from the JackPilot menu, or run 'Applications/Utilities/Audio MIDI Setup'. Then, select 'Open Aggregate Device Editor...' from the Audio menu. 4. If you wish to debug the console output of FreeWheeling for troubleshooting, start 'Applications/Utilities/Console' now. 5. Run 'FreeWheeling'. The main window should appear. If it does not, consult the Console log (step 4), or try running from a Terminal. Using FreeWheeling for Mac OS X =============================== FreeWheeling can be driven from any one MIDI source. To select the source, choose 'Preferences' from the 'Fweelin' menu. By default, FreeWheeling grabs loops with the QWERTY keys as well as one octave of keys on your MIDI keyboard. This can be configured in the configuration files. The main one is ~/.fweelin/fweelin.xml. They are all stored in ~/.fweelin. Some keyboard commands (function keys especially) may conflict with Mac OS X keyboard shortcuts. I suggest using an external USB keyboard, or modifying Freewheeling's configuration. You will have to connect audio to go into and out of FreeWheeling using Jack Pilot. Most often, you will want to route your system audio inputs into FreeWheeling, and FreeWheeling's audio outputs back out to the system, or into a sequencer or effects program. Regular Mac audio apps work with JACK. Simply point them to the 'JACK' device. FreeWheeling can also drive soft-synths and effects. FreeWheeling creates several MIDI outputs, which appear as virtual MIDI sources. You can connect your audio apps to these MIDI sources. FreeWheeling has a built-in configurable patch browser that can be used to select patches on different MIDI outputs. You can also create combination patches that split your MIDI input into a variety of keyboard zones, playing different outputs together. For a crash-course in Freewheeling (albeit, an old version), please refer to the video tutorials at: http://freewheeling.sourceforge.net/ If you'd like to configure Freewheeling, please read the configuration files located in your home folder in the hidden subfolder .fweelin/ (once you've run FreeWheeling, this folder appears) To find this folder through the Finder, you must have hidden files enabled in your Finder. Or, you can access it through the Mac Terminal app. For more help, please browse or sign on to the mailing-list. Happy Looping! -JP Mercury. Compiling FreeWheeling from Source ================================== FreeWheeling for Mac OS X can be compiled from source. Download the source package. You will need Apple's XCode tools. Load MacOSX/fweelin.xcodeproj FreeWheeling depends on several frameworks. Many of these can be installed from third-party sites. However, some, such as libsndfile, require a small amount of tweaking to be compiled as Frameworks. A ZIP file of all dependency Frameworks with xcodeproj files is available. Please contact JP Mercury: http://home.graffiti.net/swirlee/swirlee.jpg If you wish to contribute to the development of FreeWheeling, please be in touch.

Best way to understand Freewheeling?? [See and hear it][Freewheeling_Screenshots] in action. [Demo Video][Freewheeling_Demo_Video]. ### Philosophy ``` Freewheeling is a new way 'to be' In The Muse-ical Moment. It's a live looping instrument that returns us to the joy of making music 'spontaneously'. ``` Freewheeling allows us to build repetitive grooves by sampling and directing loops from within spirited improvisation. It works because, down to the core, it's built around improv. We leave mice and menus, and dive into our own process of making sound. The principle author of Freewheeling is JP Mercury. Freewheeling was also originally a Max/MSP external. Since 2016, it is maintained by the user community. ### Technical Details Freewheeling runs under GNU/Linux (PC/Mac) and Mac OS X (PPC/Intel) using the [Jack Audio Connection Kit][JACK] sound server, and is Free and Open Source Software, released under the GNU GPL license. The ChangeLog is a good resource, because all major new features have been documented there. It is humble enough to run on modest hardware but can take advantage of the gobs of RAM on modern machines as well. The only limits are your imagination. **Focus on the ideation process:** - Freewheeling empowers the trance of immediate creativity by bringing us into a circular process. Time is utterly relative, and we are freed from the future-oriented mindset of product sequencing. If inspiration flows, later arranging and editing on a timeline can be done with other tools. See the [Technical Features][Technical_Features]. Getting Started --------------- ### Downloading Pre-compiled Freewheeling binaries are available for several of today's popular operating systems. If you prefer using your favorite graphical package manager (such as synaptic) or your distro's Add/Remove Software Control Panel, search for a package named *freewheeling* or *fweelin*. - Install one of the [OS Specific Packages][OS_Specific_Packages] - (recommended) - or, [Download][Freewheeling_Tarballs] a tarball - (advanced) - or, Debian, KxStudio, Mint, and Ubuntu users can download the sourecs with your package manager: - (advanced) ``` $ apt source freewheeling ``` - or, Checkout the latest git master - (advanced) ``` $ git clone https://github.com/free-wheeling/freewheeling.git $ git clone https://notabug.org/freewheeling/freewheeling.git ``` ### Installing - [OS Specific Packages][OS_Specific_Packages] - (recommended) - [Compiling][Compiling] - (advanced) - [Dependencies][Dependencies] ### Configuring - [Configuration Basics][Configuration_Basics] - how does it work? - [XML Configuration System][XML_Configuration_System] - the full Freewheeling XML API from config-help.txt in wiki form - [Configurations][Configurations] - a store for users to submit their custom interfaces, layouts, patches, etc ### Troubleshooting and Support - [FAQS][FAQS] - Freeq-wheely Asked Questions - [Known Issues][Known_Issues] - Resolutions to common pitfalls, snags, and glitches (notice i did not say bugs) - [Freewheeling Users Mailing List][Freewheeling_Users_Mailing_List] - If you're looking for help with Freewheeling, your question may already be answered there.

A very easy way to setup a GNU/Linux audio workstation is by installing the [KxStudio Operating System][KxStudio_Downloads]. NOTE: Debian (and derrivatives such as Trisquel, Ubuntu, and Mint) can transform their system into KxStudio simply by adding the [KxStudio repos][KxStudio_Repos] and installing the 'kxstudio-meta-all' package (or 'kxstudio-meta-audio' for just the pro-audio programs). It is highly recommended that you install at least the 'kxstudio-default-settings' package which optimizes your system performance for real-time audio use. NOTE: ArchLinux (and derrivatives such as Parabola, Hyperbola, and Manjaro) can simply install the 'pro-audio' package group, which includes Freewheeling. It is highly recommended that you install at least the 'realtime-privileges' package which configures your system for real-time audio use.

Try: hdparm -c3 -d1 -m16 -A1 -u1 /dev/hda (do for /dev/hdb .. also) If you have a PCI audio interface, run setpci to set PCI latency. First, run 'lspci -v' and find the address of your audio board. Then run: setpci -s 00:07.5 latency_timer=F8 (if your audio is at 00:07.5) Set video depth to 8 or 16 bits. 24 and 32 bits are generally much slower. Use fluxbox, blackbox, or another lightweight window manager on slower machines. Use lower sampling rates to achieve lower latency. Try 64 samples, 32000 Hz, 3 periods per buffer. This works well on several low end audio boards such as ESS Maestro and AC 97. Lower latency is key for live looping! Otherwise, the latency will lag your timing and it will feel very awkward. freewheeling-0.6.6/aclocal.m4000066400000000000000000001524371370736313100160470ustar00rootroot00000000000000# generated automatically by aclocal 1.16.1 -*- Autoconf -*- # Copyright (C) 1996-2018 Free Software Foundation, Inc. # This file is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE. m4_ifndef([AC_CONFIG_MACRO_DIRS], [m4_defun([_AM_CONFIG_MACRO_DIRS], [])m4_defun([AC_CONFIG_MACRO_DIRS], [_AM_CONFIG_MACRO_DIRS($@)])]) m4_ifndef([AC_AUTOCONF_VERSION], [m4_copy([m4_PACKAGE_VERSION], [AC_AUTOCONF_VERSION])])dnl m4_if(m4_defn([AC_AUTOCONF_VERSION]), [2.69],, [m4_warning([this file was generated for autoconf 2.69.

But I'd like to give you guys somewhere to start configuring. So I've attached my current BCF-2000 preset for Freewheeling. Send it to your BCF-2000 with 'aplaymidi' or similar. Instructions for Use: Top row of 8 buttons: capture/play loops Bottom row of 8 buttons: 1- Shift (hold) Hold shift & press top 8 buttons to erase loops 2- Undo (erase last loop) 1 (Hold) + 2- Erase all loops 3- Previous page of 8 loops (or snapshots in snap mode) 4- Next page of 8 loops (or snapshots in snap mode) 5- Deselect all looops 6- Select playing loops 7- Toggle selected loops 8- Create pulse (press this after recording your first loop to lock other loops to it) Faders: 1-4 are input levels 5 is master input level 6 is master output level 7 is feedback 8 is a quick patch change slider (patches are not actually changed until you press a button- see below) Group 1 Knobs: Press 1-8 to toggle overdub for loops, Turn 1-8 to adjust loop levels Group 2 Knobs: Press 1-8 to select loops, Turn to adjust relative level of ALL selected loops Group 3 Knobs: Turn & Press Knob 8 to browse through and load scenes. Press Knob 7 to save a scene of all loops. 4 Buttons on bottom right of BCF: Top Left: Fader mode- switches BCF faders to toggle loop levels Top Right: Unused Bottom Left: Patch Change button (activate the MIDI patch you've browsed to). Bottom Right: Toggle Snap mode (In snap mode: Shows snapshots. Select snapshots with loop buttons 1-8 (top row of 8 buttons). Page through snapshots with buttons 3 and 4 on the bottom row of 8 buttons.) That's all for now.

They are well documented within and you will want to read them to get the most out of FreeEheeling. These are the most important configuration files: * basics.xml - defines the main options for freewheeling * coreinterface.xml - defines the keyboard, mouse, MIDI, and internal event bindings * graphics.xml - defines options for the graphics system (window size, fonts, etc) * interfaces.xml - definees on-screen layouts corresponding to device interfaces Creating Bindings ***************** Each binding has two parts- 1) What input event and conditions trigger the binding? 2) What output event(s) are generated and what parameters are set for those events? For example- binding: input="key" conditions="key=escape and keydown=1" output="exit-freewheeling" Is triggered when the escape key is pressed. The key must match "escape" and keydown must match "1" (the key is pressed, not released). The event generated under these conditions is "exit-freewheeling". No parameters are set. Dynamic Parameters ****************** In the above table of input events, you can see that there are different input types that can trigger events. It's possible to use simple expressions in your bindings to dynamically check conditions and assign parameters. For example- This binding is for a MIDI keyboard with volume faders that transmit on different MIDI channels. Here, the volume faders are being used to fade loop levels: binding input="midicontroller" conditions="controlnum=7 and midichannel=0>15" output="set-loop-amplifier" parameters="loopid=midichannel+36 and amp=controlval/127*2" This binding is triggered when MIDI controller 7 (volume) changes are received on channels 0-15. Event "set-loop-amplifier" is generated (to change the volume of a given loop). The loop given is "midichannel+36". The volume to set the loop to is "controlval/127*2". So, a MIDI controller 7 input on channel 2 with controller value 127 will set loop #38 to volume 2.0 (200%). The example shows how input parameters, such as MIDI channel and controller value, can be referenced in your bindings along with simple algebra (+ - / *). Order of Operations ******************* When entering algebraic expressions, note that FreeWheeling does not evaluate with standard order of operations. The order of evaluation is always left to right. So: amp="3+3/6" will evaluate to 1 and not 3 and not 3.5. Algebra is evaluated conservatively with respect to type (I'm such a conservative!) That means that the expression: amp="1/2" will evaluate to 0 and not 0.5. For explicit floating point, use: amp="1.0/2" which evaluates to 0.5. Algebra on Ranges ***************** value="0>12 + 10" evaluates to "10>22". Both ends of the range are worked on. or value="0>5 + 1>5" evaluates to "1>10". Note that the types of each end of a range are always integers, so: value="0.5>1.5 + 0.5>1.5" evaluates to "0>2" User Variables ************** It is also possible to create your own user variables. These can then be referenced in your bindings, or changed during runtime, for a much more dynamic user interface. For example, the binding below will set trigger volume for loops across a range of notes. The binding checks to see that the MIDI note number matches the user variable "VAR_noterange". Since "VAR_noterange" is a range variable, this means that the binding will only trigger event "set-trigger-volume" if the note number is within the range specified by "VAR_noterange". binding input="midikey" conditions="VAR_cutmode=1 and notenum=VAR_noterange and keydown=1" output="set-trigger-volume" parameters="loopid=notenum and vol=velocity/127" **** Note that as of version 0.5pre3, FreeWheeling automatically indexes your bindings based on a hash key, so there is no need to specify wildcard cases (previously done with midikey="*"). **** Another example... The binding: binding input="midikey" conditions="VAR_xferloop=1 and notenum=VAR_noterange adn keydown=1" output="move-loop" parameters="oldloopid=VAR_xferidx and newloopid=notenum+VAR_loopid_pianostart" Checks these conditions: Input event is a MIDI Key Variable 'VAR_xferloop' equals 1? Input parameter notenum is within range of variable 'VAR_noterange' (When comparing against a range, a condition is true when the value is within the bounds of the range) Input parameter keydown equals 1 This binding is used to move a loop onto a piano key. Presumably, this is a special case where we have a loop in a holding place (such as a loop grabbed by a footswitch), and we want to move from that holding place onto the MIDI keyboard. Using a combination of user variables and careful configuration of bindings, a highly tailored user interface can be created. Order of Bindings ***************** The order in which we declare bindings in this file is important. Bindings are checked from top to bottom, so you will need to put special case bindings first. For example, if you want to modify the behavior of a binding when a certain variable is set or key is held, you will have to put the special case before the general case. The first matching binding is the only binding that is triggered. For an example, look under comment -Erase Loops-, and see that holding space while pressing a loop trigger key erases a loop, whereas if space is not held, it triggers the loop. System Variables **************** The following system variables may also be used in configuration. They are internal to FreeWheeling and are always available. You can not change the value of these variables with events like 'set-variable' and 'toggle-variable'.System variables have special events like 'set-master-in-volume' for control. Variables: SYSTEM_midi_transpose - semitones of current MIDI transpose - affects all outgoing MIDI events to FluidSynth and the external MIDI output port SYSTEM_master_in_volume - master input volume - 1.0 is full scale SYSTEM_master_out_volume master output volume - 1.0 is full scale SYSTEM_cur_pitchbend current value of MIDI pitchbender before offset SYSTEM_bender_tune - current offset of MIDI pitchbender (see set-midi-tuning) SYSTEM_cur_limiter_gain - current autolimiter gain - changes as audio levels change it's actually more of a soft compressor SYSTEM_audio_cpu_load - current audio CPU load SYSTEM_sync_active - nonzero if transport sync is sending or receiving beats/bars/ticks This will happen whenever you have a pulse, or if another audio app is transmitting sync information. SYSTEM_sync_transmit - nonzero if Freewheeling is transmitting sync information By default, Freewheeling tries to become timebase master. When the transport starts rolling, FW will transmit sync information. If another app is master, FW will receive sync information. SYSTEM_midisync_transmit - nonzero if Freewheeling is transmitting MIDI sync information. SYSTEM_fluidsynth_enabled - is FluidSynth enabled? SYSTEM_num_help_pages - number of help pages available SYSTEM_num_loops_in_map - total number of loops in the whole map SYSTEM_num_recording_loops_in_map - total number of loops currently recording or overdubbing in map watch this to see if you have runaway loops recording SYSTEM_num_patchbanks - total number of patch banks defined in configuration SYSTEM_cur_patchbank_tag - tag for currently selected patchbank- You can use this to change Freewheeling's behavior depending on which patchbank is selected. SYSTEM_loopid_lastrecord_0 SYSTEM_loopid_lastrecord_1 SYSTEM_loopid_lastrecord_2 ... - loop ids for those loops last recorded - lastrecord_0 is the most recently recorded loop, and so on.. the number of last record appears under loops, so you can see which loops were recorded more recently SYSTEM_in_1_volume SYSTEM_in_2_volume ... - current volumes for given inputs - up to the number of inputs you have defined SYSTEM_in_1_record SYSTEM_in_2_record ... - flag for each input that tells us whether the input is set to record SYSTEM_num_midi_outs number of MIDI outputs you have defined SYSTEM_snapshot_page_firstidx index of the first snapshot on the currently visible page of snapshots SYSTEM_num_switchable_interfaces number of switchable interfaces defined SYSTEM_cur_switchable_interface index of switchable interface currently selected Browser types: BROWSE_patch Patch browser BROWSE_loop Loop browser- loads loops from disk BROWSE_scene Scene browser- loads scenes from disk Triggering Multiple Outputs *************************** You can set up one event input to trigger many output events. To do this, specify your output events and parameters for each in a list. Have a look at the binding for input="start-freewheeling", which triggers a bunch of events when FreeWheeling is first started. ** Note that as of version 0.5pre3, this new syntax replaces the old start="1" and continued="1" syntax for startup and multiple output events. ** MIDI Echo ********* FreeWheeling echos incoming MIDI events to MIDI output. However, events that trigger a binding are not echoed. This allows you to connect a softsynth or other MIDI device to one of FreeWheeling's MIDI outputs. Then MIDI inputs which trigger your event bindings, such as triggering loops, will not go to your synth. Input Events ************ Here is a table of recognized input events. The input matrix is flexible in that different types of input events can be routed to different output events. There is also a parameter routing that connects input parameters like MIDI note velocity to control parameters within FreeWheeling. For example, you can specify that the number of the note pressed controls which loop is triggered. Event "key" binding input="key" conditions="keydown=1 and key=space" A keyboard key is pressed or released. "keydown": 1 if key was pressed, otherwise 0 "key": Name or number of the key (see above table) Event "midicontroller" binding input="midicontroller" conditions="controlnum=64 and midichannel=0 and controlval=64>127" A MIDI controller is changed. "outport": # of MIDI output to echo event to (1 is the first port) "midichannel": Channel of event (0 is the first channel) "controlnum": Number of control change "controlval": Value of control change "routethroughpatch": 1 sends this MIDI message through the port/channel(s) given by the current patch. 0 sends this message as described by outport/midichannel. Event "midikey" binding input="midikey" conditions="keydown=1 and midichannel=0 and notenum=VAR_noterange and velocity=1>127" A MIDI note is pressed or released. "outport": # of MIDI output to echo event to (1 is the first port) "keydown": 1 if note is pressed, 0 if note is released "midichannel": Channel of event (0 is the first channel) "notenum": Number of note "velocity": Velocity of noteon/noteoff "routethroughpatch": 1 sends this MIDI message through the port/channel(s) given by the current patch. 0 sends this message as described by outport/midichannel. Event "midichannelpressure" binding input="midichannelpressure" conditions="midichannel=0 and pressureval=64" A MIDI channel pressure (channel aftertouch) message. "outport": # of MIDI output to echo event to (1 is the first port) "midichannel": Channel of event (0 is the first channel) "pressureval": Pressure of keys "routethroughpatch": 1 sends this MIDI message through the port/channel(s) given by the current patch. 0 sends this message as described by outport/midichannel. Event "midiprogramchange" binding input="midiprogramchange" conditions="midichannel=0 and programval=64" A MIDI program change message. "outport": # of MIDI output to echo event to (1 is the first port) "midichannel": Channel of event (0 is the first channel) "programval": Program change # "routethroughpatch": 1 sends this MIDI message through the port/channel(s) given by the current patch. 0 sends this message as described by outport/midichannel. Event "midipitchbend" binding input="midipitchbend" conditions="midichannel=0 and pitchval=6000" A MIDI pitch bend message. "outport": # of MIDI output to echo event to (1 is the first port) "midichannel": Channel of event (0 is the first channel) "pitchval": Pitch bender value "routethroughpatch": 1 sends this MIDI message through the port/channel(s) given by the current patch. 0 sends this message as described by outport/midichannel. Event "joybutton" binding input="joybutton" conditions="joystick=1 and button=3 and down=1" A joystick button has been moved. "joystick": # of the joystick "button": # of the button "down": 1 if button is down, 0 if button is up Event "start-freewheeling" binding input="start-freewheeling" FreeWheeling has just been started. Event "go-sub" binding input="go-sub" Subroutine is being invoked- see "go-sub" in output events. The above input events can also be used as output events. For example, we can trigger a series of MIDI controller changes when a QWERTY key is pressed. Output Events ************* Here is a table of recognized output events, what they do and what parameters they accept: Event "exit-freewheeling" Quit! Event "slide-loop-amplifier-stop-all" Stops sliding amplitudes for all loops. Event "slide-loop-amplifier" Slides the amplitude of a given loop, like a fade. "loopid": the ID of the loop "slide": the speed at which to slide the amplitude. Successive events accelerate the sliding, until you reverse the speed or call set-loop-amplifier Event "set-loop-amplifier" Sets the amplitude of a given loop, and stops any sliding "loopid": the ID of the loop "amp": the amplitude to set it to (linear) Event "adjust-loop-amplifier" Adjusts the amplitude of a given loop, and stops any sliding "loopid": the ID of the loop "ampfactor": the factor to multiply the amplitude by Event "trigger-loop" Triggers a given loop- if no loop exists at that loopid, begins recording a new loop.. if a new loop is recording, the behavior depends: if overdub="1", switches to overdub.. if overdub="0", switches to play.. if a loop is playing, the behavior depends: if overdub="1", switches to overdub.. if overdub="0", switches off.. if a loop is overdubbing, switches to play. This is similar to an EDP style tapin-tapout-play/overdub. When recording a new loop, the length grows until we trigger-loop again. When overdubbing into an existing loop, the existing loop is blended with new input material. You can modify this behavior with the "engage" option. When "engage" is set to 1, the loop will -always- start. When "engage" is set to 0, the loop will -always- stop. If engage is not set, the behavior depends on the current state of the loop, as described above. You can modify the looping behavior with the "shot" option. When "shot" is set to 1, the loop will play through only once. When "shot" is not set, the loop will repeat indefinitely. "loopid": the ID of the loop "vol": the volume to trigger with- this combined with the loop amplitude determine the overall amplitude of the playing loop "shot": shot mode "engage": force on or off? "overdub": 1 or 0 determine whether to overdub or just play "overdubfeedback": Variable that holds the value of feedback to apply during overdub. Variable must be of type float (from 0.0 to 1.0). Variable can be continuously varied. Event "set-trigger-volume" Sets the volume of a given loop trigger. If you have a loop playing, you can change the volume with this event. It is different than the loop amplifier, because each time you trigger the loop you can have a different trigger volume, whereas the loop amplifier changes the volume of the loop once-and-for-all. "loopid": the ID of the loop "vol": the volume to set it to Event "erase-selected-loops" Erase selected loops that are in the given selection set. "setid": Number of the selection set to use (usually this will be 0) Event "erase-all-loops" Erases all loops and time meters. Event "erase-loop" Erases a given loop- if recording is happening on the given id, stops and erases recording. "loopid": the ID of the loop Event "move-loop" Moves a loop from "oldloopid" to "newloopid", if a loop exists there. This can be done at any time- when recording or playing a loop, or when it is inactive. "oldloopid": old loop ID "newloopid": new loop ID Event "slide-master-in-volume" Slides the master input volume at the speed given. A positive value increases volume. Actually, if you call slide-master-in-volume several times you cumulatively increase the speed of sliding. It is like a fade. This applies for other slide events too. "slide": speed of slide Event "slide-in-volume" Slides one input volume at the speed given. A positive value increases volume. "input": number of input to slide volume for "slide": speed of slide Event "slide-master-out-volume" Slides the master output volume at the speed given. A positive value increases volume. "slide": speed of slide Event "set-master-in-volume" Sets the master input volume. Stops sliding. "vol": new linear volume- 1.0 is 100% volume. or "fadervol": new logarithmic volume- specify fader throw (0.0 to 1.0). Event "set-master-out-volume" Sets the master output volume. Stops sliding. "vol": new linear volume- 1.0 is 100% volume. or "fadervol": new logarithmic volume- specify fader throw (0.0 to 1.0). Event "set-in-volume" Sets one input volume. Stops sliding. "input": number of input to set volume for "vol": new linear volume- 1.0 is 100% volume. or "fadervol": new logarithmic volume- specify fader throw (0.0 to 1.0). Event "toggle-input-record" Toggles recording of one input. Does not change monitoring for this input, only whether loops are recorded from the input. "input": number of input to toggle recording for Event "adjust-midi-transpose" Adjusts the pitch transpose for MIDI out. MIDI events that aren't used in an event are echoed back out the MIDI out and to the internal FluidSynth synthesizer. This parameter adjusts the transpose that is applied to MIDI notes before they are echoed. It does not affect the note numbers coming into FreeWheeling events. "adjust": amount to shift transpose (semitones) Event "fluidsynth-enable" Enables or disables processing for the integrated FluidSynth. When FluidSynth is disabled, the real-time DSP for FluidSynth is not active, so FreeWheeling runs faster. By default, this is done by the patch browser. When you select FluidSynth patches, FluidSynth is enabled. When you select other patches, FluidSynth is automatically disabled. "enable": 1 for enable or 0 for disable Event "set-midi-tuning" Retunes MIDI by the current value of the pitchbender. What this does is offset the zero position of pitchbender to a given value. You can easily tune to outside instruments by sweeping the pitchbender until you are in tune and then calling set-midi-tuning with the current value of the pitchbender (see system variables). "tuning": new zero position for MIDI pitchbender Event "set-midi-echo-port" DEPRECATED- FreeWheeling now sends to ports/channels as specified by the patch browser. Sets the MIDI port where incoming MIDI events are echoed. The only events echoed are those that do not trigger something in FreeWheeling. "echoport": new MIDI out port number to echo MIDI events (0 disables) Event "set-variable" Sets the user variable named "var" to the value "val". The value given must be convertible into the type of variable "var". "var": variable to set "value": what to set it to Event "toggle-variable" Toggles (increments) the user variable named "var" through an integer range of values, with a maximum of "maxvalue". Wraps to "minvalue" when maxvalue is exceeded. "var": variable to toggle "maxvalue": maximum value of variable "minvalue": minimum value of variable Event "video-show-loop" Change the range of loops shown onscreen- In the onscreen layout given by "layoutid", shows loops in the range "loopid". For example, if you specify layoutid 0 and loopid 15>30, then layout 0 will show the loop at id 15 in its first element (element id 0), up to loopid 30 in element 15. You will see these changes only if the layout is set to show onscreen, and when there are loops stored in the loopids given. "interfaceid": interface where layout is defined "layoutid": which layout to change the range of shown loops "loopid": new range of shown loops Event "video-show-layout" Shows or hides the layout given by "layoutid". If hideothers is "1", all other layouts are made hidden. "interfaceid": interface where layout is defined "layoutid": layout to show/hide "show": "1" for show and "0" for hide "hideothers": "1" to hide all other layouts Event "video-switch-interface" Switches to (shows) the interface given by "interfaceid". All displays and layouts defined in that interface are shown. All displays and layouts defined in other interfaces are hidden, EXCEPT those in non-switchable interfaces. "interfaceid": interface to switch to Event "video-show-help" Shows or hides help. FreeWheeling has an online help that can be overlaid on the screen while you are playing. This event shows a given page of that help (or hides it). The help text is user defined. Throughout this config file, you'll see comments which begin in "HELP:". Any comments that begin in this way become a part of the help text. If you have a second ":" in the help comment, it becomes a second column in the help text. "page": Help page number to show or "0" for hide Event "video-full-screen" Put FreeWheeling in a window, or let 'er hog the whole screen "fullscreen": "1" for hog fullscreen and "0" for window Event "select-pulse" Selects time pulse #pulse. If no pulse exists at the given #, creates a new one. The length and downbeat of a new pulse are taken from the last recorded loop. Once a pulse is created, it is automatically selected. The selected pulse determines the timing of all newly recorded loops. If a new pulse is selected, only those loops recorded from that point on are affected. To deselect all pulses and return to free time, set pulse="-1". "pulse": Number of the time pulse to create/select Event "delete-pulse" Delete time pulse #pulse. All loops attached to that pulse are also deleted. "pulse": Number of the time pulse to delete Event "show-debug-info" Shows or hides debugging information. The information is printed to the console. It includes input events like MIDI and keyboard keys, and information from bound events. It can help track down problems in your configuration, if FreeWheeling is not working as you imagined. But it introduces some performance latency, so I recommend leaving it off! "show": "1" for show debug info and "0" for hide Event "toggle-disk-output" Toggles output of the master outs to disk. This includes the input mix. OGG files are created in the library folder with the name 'live1.ogg', 'live2.ogg', etc.. The live mix is exactly what you hear from FreeWheeling's outputs. Accompanying each OGG file is a timing file named live.wav.usx, to be used in the GnuSound editor for doing precise splice edits on loop downbeats. Run oggdec on the OGG files and then load into GnuSound. You can also import timing information into Ardour from this .wav.usx file- see the file scripts/go-import-markers. If FreeWheeling is already writing to disk, this shuts the record off. The next write starts in a new folder. FreeWheeling no longer overwrites old files and folders. Existing save folders are skipped. Event "set-auto-loop-saving" Turns on/off auto loop saving. This saves all new loops to disk. The loops are saved in the current "save" folder (see toggle-disk-output), with the name 'loop???.ogg'. The loopID is given in the filename. Loop files are not overwritten- subsequent writes of 55, for example, will yield filenames 'loop55-0.ogg', 'loop55-1.ogg', etc. "save": "1" to turn on auto loop saving and "0" for off Event "save-loop" Saves the loop with given index. The file is named and saved as described above. "loopid": ID of loop to save Event "save-new-scene" Event "save-current-scene" Saves a new scene/overwrites current scene. A scene is a snapshot of all loaded loops and levels. It is like a save of the complete session. Event "create-snapshot" Create a snapshot. A snapshot is a memory of all playing and idle loops and their levels. This allows you to easily create and switch between song 'sections'. "snapid": ID # of snapshot to save Event "rename-snapshot" "snapid": ID # of snapshot to rename Event "trigger-snapshot" "snapid": ID # of snapshot to trigger Event "swap-snapshots" Swap two snapshots. "snapid1": ID # of first snapshot "snapid2": ID # of second snapshot Event "switch-metronome" Switches an audible metronome on or off for the given pulse. The metronome sounds on the downbeat of the pulse. "pulse": Number of the pulse "metronome": 1 for metronome on, 0 for off Event "tap-pulse" Taps a pulse- each tap gives a new downbeat. This allows you to tap tempo, instead of creating a pulse around an existing loop. If you tap a tempo and switch-metronome to on, it is like playing along with a click track. If you already have loops playing on a pulse, the effect is to change the timing when they loop to their start. The loops themselves do not change speed (yet). "pulse": Number of the pulse "newlen": 1 for change tempo, 0 for just hit downbeat Event "go-sub" Triggers event "go-sub", which you can bind to. The effect is like creating a subroutine of several event triggers. You can then trigger go-sub from many places, and have the same subroutine of events triggered. This allows you to have FreeWheeling do several predefined things in response to one input, like changing loop volumes and moving loops, or repeating some operation on several loops. You can have many subroutines, and each subroutine can accept parameters. Search for go-sub to find examples in this config. "sub": Number of the subroutine "param1": Integer parameter 1 "param2": Integer parameter 2 "param3": Integer parameter 3 Event "browser-move-to-item" Moves forward or back in a browser "browserid": Browser ID- as you have defined in 'display' section "adjust": Number of individual items to move by (+ is forward - is back) "jumpadjust": number of divisions to jump by divisions are placed depending on the type of browser- for example, for Fluidsynth patches, there are divisions between soundfonts Event "browser-select-item" Choose or select the current item in a browser. Different browser types behave differently when an item is selected For example, the loop browser loads the selected loop "browserid": Browser ID- as you have defined in 'display' section Event "browser-rename-item" Rename the current item in a browser. This is an interactive process where the user can make changes to the item name. Many of the regular keyboard bindings become disabled during renaming. During renaming, you can type a new name with the keyboard. ESC aborts renaming, and ENTER accepts the new name. "browserid": Browser ID- as you have defined in 'display' section Event "patchbrowser-move-to-bank" Switch patch browser banks. "direction": -1 or 1 to move backward or forward Event "patchbrowser-move-to-bank-by-index" Switch patch browser banks, choosing by index. "index": Index of patchbank to select Must be in the range of 0 to SYSTEM_num_patchbanks-1 Event "browser-item-browsed" This event is sent out by Freewheeling's browsers whenever a browser item is changed. This is useful in the patch browser- you can bind to browser-item-browsed and send out control changes or change MIDI echo ports whenever a new item is browsed. "browserid": Browser ID- as you have defined in 'display' section. Identifies which browser has had a change in item. Event "video-show-display" Show or hide a video display with the given ID- you define the displays and IDs in the video section below, and then you can turn them on or off as needed through this event. "interfaceid": interface where layout is defined "displayid": Display ID "show": 1 or 0 is show or hide display Event "set-load-loop-id" Sets the loop ID where to put a loop when it is loaded from disk. Loops are loaded by the loop browser when an item is selected (browser-select-item). Whenever a single loop is loaded from disk, it will appear in this loop ID. "loopid": ID to load loops into Event "set-default-loop-placement" Sets the range of loop IDs to be used by default. For example when loading external loops, FW can place them here if the requested IDs are not available. "looprange": Range of IDs to use as default Event "loop-clicked" This event is generated whenever the user clicks a mouse button on a loop slot on-screen. It allows you to respond to clicks on loops. "down": Mouse button down or up? (1 or 0) "button": Number of mouse button pressed/released "loopid": Number of the corresponding loopid clicked on "in": Zero if the loop was clicked in the loop tray One if the loop was clicked in a layout Event "set-sync-type" Set the type of sync for syncronizing to an external sequencer/app. Freewheeling uses a 'pulse' concept of timing. Instead of dividing time up into bars, beats, and ticks (sequencer style), Freewheeling simply defines time as a rhythmic pulsing. When you create a pulse, Freewheeling can optionally transmit or receive sync information for that pulse. Two syncronization mechanisms are provided- Jack and MIDI. Both represent time as bars, beats, and ticks. The sync type parameter controls whether we are mapping beats to pulses (beat sync) or bars to pulses (bar sync). "type": 1 for beat sync, 0 for bar sync Event "set-sync-speed" Set the number of beats/bars per pulse. This affects the translated speed between Freewheeling's internal clock and the external clock. "speed": Number of beats or bars (depending on sync type) to a single pulse. Event "set-midi-sync" Set whether to transmit MIDI sync. Note that to transmit MIDI sync, you also need to set 'midisyncouts' in the general config section, and you need to have a pulse running. "midisync": 1 to transmit MIDI sync. 0 for no MIDI sync. Event "toggle-select-loop" Freewheeling allows you to select and work with several loops at once. This event toggles one loop as selected/unselected. You can have several selection sets. "setid": Number of the selection set in which to toggle the loop (usually this will be 0) "loopid": ID of the loop to toggle Event "select-only-playing-loops" Make the selection include only those loops that are currently playing/ currently idle. "setid": Number of the selection set to change (usually this will be 0) "playing": 1 to include only playing loops 0 to include only idle loops Event "select-all-loops" Select/unselect all loops. "setid": Number of the selection set to change (usually this will be 0) "select": 1 to select all loops 0 to select no loops Event "invert-selection" Invert the selection- Select all loops not currently selected. "setid": Number of the selection set to change (usually this will be 0) Event "trigger-selected-loops" Trigger the selected loops. You can toggle them for playing/idle, or you can force them to play. "setid": Number of the selection set to use (usually this will be 0) "vol": Volume at which to trigger loops "toggleloops": 1 to toggle loops for playing, 0 to force playing.

Here's ## why we pick this rather obscure method: ## - Don't want to use -MD because we'd like the dependencies to end ## up in a subdir. Having to rename by hand is ugly. ## (We might end up doing this anyway to support other compilers.) ## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like ## -MM, not -M (despite what the docs say).

We avoid this by adding ## dummy dependencies for each header file. Too bad gcc doesn't do ## this for us directly. ## Some versions of gcc put a space before the ':'. On the theory ## that the space means something, we add a space to the output as ## well. hp depmode also adds that space, but also prefixes the VPATH ## to the object. Take care to not repeat it in the output. ## Some versions of the HPUX 10.20 sed can't process this invocation ## correctly.

This allows you to control several different sounds or softsynths from one MIDI control source. A patch defines the zones, as well as the output port and channel that each zone sends to. You can also send MIDI program and bank change messages for each zone, allowing you to switch programs on external synths. All of this functionality is integrated into the patch browser, so you can seamlessly control other synth apps and sound modules from within FreeWheeling. See 'examples/combipatchdemo.xml' for an example configuration. Patch Browser Definition Example -------------------------------- The file patches1.xml contains an example for how to define patches for an external soft synth. In this case it's an example for a Ghostess DSSI host running one instance of WhySynth and one instance of Hexter. To use this example, copy 'examples/patches1.xml' to the ~/.fweelin/ folder (this folder is created by version 0.5.2 and forward). The WhySynth instance is on channel 0 (first channel), and the Hexter instance is on channel 1 (second channel). When you specify this patch list in Freewheeling's .fweelin.rc configuration file: you will then be able to play both your WhySynth and your Hexter patches, and switch between them. The WhySynth and Hexter patches will appear in separate sections of the patch browser. ------------------------------------------------------------------------------------------- You can automatically generate a patch list from a set of DSSI plugin patches. This saves the work of manually entering all of your patch information. To do this, apply the included patch to Ghostess (scripts/patch-ghostess-xml-patchlist). The patch modifies Ghostess so that when you select 'Save Configuration...' from the File menu, you get both a script to startup Ghostess with the current config and patchset, -as well as- an .XML file with the same base name, that contains the patch list for Freewheeling. I've submitted this patch to Sean Bolton for inclusion in an upcoming Ghostess release. Please nudge him if it has been useful for you (http://home.jps.net/~musound/). ------------------------------------------------------------------------------------------- freewheeling-0.6.6/examples/combipatchdemo.xml000066400000000000000000000026771370736313100215250ustar00rootroot00000000000000 freewheeling-0.6.6/examples/patches1.xml000066400000000000000000000617171370736313100202570ustar00rootroot00000000000000 freewheeling-0.6.6/install-sh000077500000000000000000000360101370736313100161770ustar00rootroot00000000000000#!/bin/sh # install - install a program, script, or datafile scriptversion=2018-03-11.20; # UTC # This originates from X11R5 (mit/util/scripts/install.sh), which was # later released in X11R6 (xc/config/util/install.sh) with the # following copyright and license. # # Copyright (C) 1994 X Consortium # # Permission is hereby granted, free of charge, to any person obtaining a copy # of this software and associated documentation files (the "Software"), to # deal in the Software without restriction, including without limitation the # rights to use, copy, modify, merge, publish, distribute, sublicense, and/or # sell copies of the Software, and to permit persons to whom the Software is # furnished to do so, subject to the following conditions: # # The above copyright notice and this permission notice shall be included in # all copies or substantial portions of the Software. # # THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR # IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, # FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

See individual files for instructions. ** goarchive-scene script Archive a scene and all the loops it uses. Connecting FreeWheeling with Other Linux Audio apps --------------------------------------------------- -Hexter -Jack-Rack Example Scripts and Presets: --------------------------- Several Jack-Racks that use tube amp sims and reverb, and some scripts to load FreeWheeling and Hexter, a killer DX7 synth emulator. - Running 'gofweel' will load FreeWheeling and hook it up to reverb and tube amp. Your live mix will still be saved to disk dry, so you can tweak the FX later. - Running 'godx7' will load Hexter DX7 emulator and connect to tube amp. If FreeWheeling is running, DX7 becomes an input into FreeWheeling (channel 2). If not, DX7 is loaded standalone. - Running 'gofweel-dx7' will load FreeWheeling and DX7 as above, and connect them. You get the DX7 synth connected through a light phaser, then into FreeWheeling. FreeWheeling is channeled through valve saturation and tube amp plugins, and a wide open reverb. This is the whole enchilada. *** You will have to tweak the scripts to change your MIDI hardware name- see script 'waitalsaports'. *** *** You will also have to patch Jack-Rack (see included patch-) to load a .rack at startup. This is a feature that the author, I think, intends to implement, but I have done it for him. The scripts use this feature to autoload a rack. For more info, type 'jack-rack -?' after patching and recompiling and look at the -f option. *** *** Note these scripts are rather aggressive at killing tasks. If you have running versions of freewheeling, ghostess, jack-dssi-host, or jack-rack, expect them to suddenly stop! ** *** I recommend ghostess for hosting your DSSI synths- it allows you to save patch banks for auto startup.

The second * argument is a filedescriptor that StackTrace() writes to. If this * argument is -1 then standard output will be used. * * Compilation: * Some platforms have a built-in method to generate stacktraces, but * they are usually located in some non-standard library. The following * are supported: * * IRIX Compile with -DUSE_BUILTIN and -lexc * HP/UX Compile with -DUSE_BUILTIN and -lcl * GCC Compile with -DUSE_BUILTIN * ************************************************************************/ #ifndef H_DEBUG_STACKTRACE #define H_DEBUG_STACKTRACE #if defined(__cplusplus) extern "C" { #endif // __cplusplus void StackTrace(char *gdb_command_file); void StackTraceInit(const char *progname, int handle); #if defined(__cplusplus) } #endif // __cplusplus #endif /* H_DEBUG_STACKTRACE */
