The Free Translation Project is a way to get maintainers of free software, translators, and users all together, so that will gradually become able to speak many languages. A few packages already provide translations for their messages. If you found this `ABOUT-NLS' file inside a distribution, you may assume that the distributed package does use GNU `gettext' internally, itself available at your nearest GNU archive site. But you do _not_ need to install GNU `gettext' prior to configuring, installing or using this package with messages translated. Installers will find here some useful hints. These notes also explain how users should proceed for getting the programs to use the available translations. They tell how people wanting to contribute and work at translations should contact the appropriate team. When reporting bugs in the `intl/' directory or bugs which may be related to internationalization, you should tell about the version of `gettext' which is used. The information can be found in the `intl/VERSION' file, in internationalized packages. Quick configuration advice ========================== If you want to exploit the full power of internationalization, you should configure it using ./configure --with-included-gettext to force usage of internationalizing routines provided within this package, despite the existence of internationalizing capabilities in the operating system where this package is being installed. So far, only the `gettext' implementation in the GNU C library version 2 provides as many features (such as locale alias, message inheritance, automatic charset conversion or plural form handling) as the implementation here. It is also not possible to offer this additional functionality on top of a `catgets' implementation. Future versions of GNU `gettext' will very likely convey even more functionality. So it might be a good idea to change to GNU `gettext' as soon as possible. So you need _not_ provide this option if you are using GNU libc 2 or you have installed a recent copy of the GNU gettext package with the included `libintl'. INSTALL Matters =============== Some packages are "localizable" when properly installed; the programs they contain can be made to speak your own native language. Most such packages use GNU `gettext'. Other packages have their own ways to internationalization, predating GNU `gettext'. By default, this package will be installed to allow translation of messages. It will automatically detect whether the system already provides the GNU `gettext' functions. If not, the GNU `gettext' own library will be used. This library is wholly contained within this package, usually in the `intl/' subdirectory, so prior installation of the GNU `gettext' package is _not_ required. Installers may use special options at configuration time for changing the default behaviour. The commands: ./configure --with-included-gettext ./configure --disable-nls will respectively bypass any pre-existing `gettext' to use the internationalizing routines provided within this package, or else, _totally_ disable translation of messages. When you already have GNU `gettext' installed on your system and run configure without an option for your new package, `configure' will probably detect the previously built and installed `libintl.a' file and will decide to use this. This might be not what is desirable. You should use the more recent version of the GNU `gettext' library. I.e. if the file `intl/VERSION' shows that the library which comes with this package is more recent, you should use ./configure --with-included-gettext to prevent auto-detection. The configuration process will not test for the `catgets' function and therefore it will not be used. The reason is that even an emulation of `gettext' on top of `catgets' could not provide all the extensions of the GNU `gettext' library. Internationalized packages have usually many `po/LL.po' files, where LL gives an ISO 639 two-letter code identifying the language. Unless translations have been forbidden at `configure' time by using the `--disable-nls' switch, all available translations are installed together with the package. However, the environment variable `LINGUAS' may be set, prior to configuration, to limit the installed set. `LINGUAS' should then contain a space separated list of two-letter codes, stating which languages are allowed. Using This Package ================== As a user, if your language has been installed for this package, you only have to set the `LANG' environment variable to the appropriate `LL_CC' combination. Here `LL' is an ISO 639 two-letter language code, and `CC' is an ISO 3166 two-letter country code. For example, let's suppose that you speak German and live in Germany. At the shell prompt, merely execute `setenv LANG de_DE' (in `csh'), `export LANG; LANG=de_DE' (in `sh') or `export LANG=de_DE' (in `bash'). This can be done from your `.login' or `.profile' file, once and for all. You might think that the country code specification is redundant. But in fact, some languages have dialects in different countries. For example, `de_AT' is used for Austria, and `pt_BR' for Brazil. The country code serves to distinguish the dialects. The locale naming convention of `LL_CC', with `LL' denoting the language and `CC' denoting the country, is the one use on systems based on GNU libc. On other systems, some variations of this scheme are used, such as `LL' or `LL_CC.ENCODING'. You can get the list of locales supported by your system for your country by running the command `locale -a | grep '^LL''. Not all programs have translations for all languages. By default, an English message is shown in place of a nonexistent translation. If you understand other languages, you can set up a priority list of languages. This is done through a different environment variable, called `LANGUAGE'. GNU `gettext' gives preference to `LANGUAGE' over `LANG' for the purpose of message handling, but you still need to have `LANG' set to the primary language; this is required by other parts of the system libraries. For example, some Swedish users who would rather read translations in German than English for when Swedish is not available, set `LANGUAGE' to `sv:de' while leaving `LANG' to `sv_SE'. In the `LANGUAGE' environment variable, but not in the `LANG' environment variable, `LL_CC' combinations can be abbreviated as `LL' to denote the language's main dialect. For example, `de' is equivalent to `de_DE' (German as spoken in Germany), and `pt' to `pt_PT' (Portuguese as spoken in Portugal) in this context. Translating Teams ================= For the Free Translation Project to be a success, we need interested people who like their own language and write it well, and who are also able to synergize with other translators speaking the same language. Each translation team has its own mailing list. The up-to-date list of teams can be found at the Free Translation Project's homepage, `http://www.iro.umontreal.ca/contrib/po/HTML/', in the "National teams" area. If you'd like to volunteer to _work_ at translating messages, you should become a member of the translating team for your own language. The subscribing address is _not_ the same as the list itself, it has `-request' appended. For example, speakers of Swedish can send a message to `sv-request@li.org', having this message body: subscribe Keep in mind that team members are expected to participate _actively_ in translations, or at solving translational difficulties, rather than merely lurking around. If your team does not exist yet and you want to start one, or if you are unsure about what to do or how to get started, please write to `translation@iro.umontreal.ca' to reach the coordinator for all translator teams. The English team is special. It works at improving and uniformizing the terminology in use. Proven linguistic skill are praised more than programming skill, here. Available Packages ================== Languages are not equally supported in all packages. The following matrix shows the current state of internationalization, as of May 2003. The matrix shows, in regard of each package, for which languages PO files have been submitted to translation coordination, with a translation percentage of at least 50%.

preceding matrix are higher than the number of visible blocks let us expect. This is because a few extra PO files are used for implementing regional variants of languages, or language dialects. For a PO file in the matrix above to be effective, the package to which it applies should also have been internationalized and distributed as such by its maintainer. There might be an observable lag between the mere existence a PO file and its wide availability in a distribution. If May 2003 seems to be old, you may fetch a more recent copy of this `ABOUT-NLS' file on most GNU archive sites. The most up-to-date matrix with full percentage details can be found at `http://www.iro.umontreal.ca/contrib/po/HTML/matrix.html'. Using `gettext' in new packages =============================== If you are writing a freely available program and want to internationalize it you are welcome to use GNU `gettext' in your package. Of course you have to respect the GNU Library General Public License which covers the use of the GNU `gettext' library. This means in particular that even non-free programs can use `libintl' as a shared library, whereas only free software can use `libintl' as a static library or use modified versions of `libintl'. Once the sources are changed appropriately and the setup can handle the use of `gettext' the only thing missing are the translations. The Free Translation Project is also available for packages which are not developed inside the GNU project. Therefore the information given above applies also for every other Free Software Project. Contact `translation@iro.umontreal.ca' to make the `.pot' files available to the translation teams. swami-2.2.0/AUTHORS000066400000000000000000000006171361104770400137120ustar00rootroot00000000000000Element Green Contributors: BALATON Zoltan for Spectralis support, Mac OS X integration and MAC builds.

GNU GENERAL PUBLIC LICENSE Version 2, June 1991 Copyright (C) 1989, 1991 Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. 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 Lesser 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.

Now using GType GParamSpec if available (Glib 2.10.0) with fallback to gulong (instead of guint). * src/swamigui/SwamiguiTree.c: Added conditional for use of GTK 2.10.0 only function gdk_atom_intern_static_string(). 2007-04-20 Josh Green * configure.ac: Added --disable-python configure option. * swami-2.png: Updated with new blurry feature of Inkscape, to give some software edge effects. * src/swamigui/SwamiguiDnd.h: Changed SWAMIGUI_DND_WIDGET_INFO and SWAMIGUI_DND_WIDGET_NAME to SWAMIGUI_DND_OBJECT_INFO and SWAMIGUI_DND_OBJECT_NAME respectively, since they will be used for passing arbitrary GObject's within Swami. * src/swamigui/SwamiguiSampleEditor.c: Added buttons for sample cut, crop and new from selection. Added selection support using marker 0. Initial function stubs are there for sample operation buttons, but don't do anything yet. Added swamigui_sample_editor_set_marker() function. * src/swamigui/SwamiguiStatusbar.c: Added "default-timeout" property which is used for messages which use the SWAMIGUI_STATUSBAR_TIMEOUT_DEFAULT value. Added swamigui_statusbar_printf() for added convenience in sending executed operation status messages to status bar. * src/swamigui/SwamiguiTree.c: Added support for paste operations using drag and drop and high level tree DnD API. Unfortunately this doesn't currently support multiple item drag and drop, so only 1 item at a time can be pasted using this method (plan to hack in code to implement custom multi-item drag and drop, or wait for GTK support). 2007-03-21 Josh Green * src/swamigui/SwamiguiSampleEditor.c: Moved zoom/scroll canvas functionality to a new separate object SwamiguiCanvasMod. Loop cross section viewer is now also zoomable. Added swamigui_sample_editor_loop_zoom() function to set zoom of loop view. * src/swamigui/SwamiguiTree.c: When item selection is assigned to tree it now expands all parents of selected items and makes the first item in view. * src/swamigui/patch_funcs.c: swamigui_new_item() now sets new item as current selection. swamigui_cb_load_samples_response() now sets current item selection to added samples. * src/swamigui/SwamiguiItemMenu_actions.c: "copy" action now excluded for virtual container types.

Contributions without following these guidlines are ok, but it likely means more work for me, since I'll probably modify things so that it is correctly assimulated. Code style --------------- Code indentation style is pretty much the GNU style of the 'indent' command with a couple exceptions: Braces are not indented (i.e., they are on the same column as the statement they follow). Note that currently most of the project does in fact have 2 space brace indenting, but I'd like to change that. Also, pointer arguments in functions don't have a space between the * and the argument name (anyone know how to turn that off with indent?) Example: int function (GObject *obj, int arg) { int i; if (1 == 1) { for (i = 0; i < 0; i++) { printf ("This coding style is yummy!\n"); } } } The following indent command will get things almost right. If anyone knows how to turn off the spaces between the * in function pointer arguments and the argument name, do let me know. For some reason that just annoys the hell out of me ;) The other thing that is annoying is breaking lines on _("") macro i18n calls, but I doubt indent can be forced to not to do that. If I could fix those two issues I'd probably run indent on all the code, since the current bracing indentation style is not to my liking. indent -bli0 -sc -ncs myfile.c Commenting code --------------- Please comment all new public functions with GTK doc style comment blocks. Refcounting/memory allocation is also good to comment. Please do so like this: sf2 = ipatch_sf2_new (); /* ++ ref */ file = ipatch_file_new (); /* ++ ref */ ptr = g_new (MyStruct, 1); /* ++ alloc */ ... g_free (ptr); /* -- free */ g_object_unref (file); /* -- unref */ return (sf2); /* !! caller takes over reference */ So in other words, use "++" to indicate an allocate or object reference, "--" to indicate free or object unref and "!!" to indicate something special with allocation or reference counting (such as returning allocated or referenced object to caller). In this way it should be easy to scan a function quickly and notice if there are any ref/allocation issues (an unref forgotten, etc). swami-2.2.0/INSTALL000066400000000000000000000044321361104770400136720ustar00rootroot00000000000000+-------------------------------------------------------+ + Swami - Installation + + Copyright (C) 1999-2002 Josh Green + + Email: jgreen@users.sourceforge.net + + Swami homepage: http://swami.sourceforge.net + +-------------------------------------------------------+ If compiling from CVS ----------------- You need to run "./autogen.sh" in the toplevel directory. You'll need autoconf, automake, libtool and perhaps other libraries and there development packages in order for this to work. Configure build system ----------------- Change to toplevel Swami source directory and execute: ./configure Some useful options to the configure script ("./configure --help" to list more options) you probably won't need to specify any of these: --with-audiofile-prefix=PFX Prefix where AUDIOFILE is installed (optional) --disable-splash Don't compile Swami splash intro image TIPS in using the configure script ----------------- Support for external libraries is for the most part auto detected. So you probably won't need to supply any switches to the configure script. If the configure script does something unexpected or fails it is often useful to look at the config.log file. If you install or remove a library used by Swami and you want to re-run configure, you may want to delete config.cache first. Required libraries ----------------- Swami requires a sound file library to load sample files (WAV, AU etc). Currently only audiofile is supported (libsndfile support soon). audiofile homepage: http://www.68k.org/~michael/audiofile/ libsndfile homepage: http://www.zip.com.au/~erikd/libsndfile/ GTK 1.2+ is required. It depends on a number of other libraries as well. Chances are you already have it. GTK homepage: http://www.gtk.org Optional libraries ----------------- The libpng library is used for the splash intro image. If you don't have it you won't get the splash image. You can also force the splash image to not be compiled (save about 60k in the Swami binary, but lose some of the Swami atmosphere) with the --disable-splash switch. Compile and install ----------------- To compile the package execute: make To install the binary file "swami" issue a: make install Please contact me (Josh Green ) if you have problems or suggestions with the build process. swami-2.2.0/NEWS000066400000000000000000000015311361104770400133350ustar00rootroot00000000000000+-------------------------------------------------------+ + Smurf Sound Font Editor - News + + Copyright (C) 1999-2002 Josh Green + + Email: jgreen@users.sourceforge.net + + Smurf homepage: http://smurf.sourceforge.net + +-------------------------------------------------------+ Jun 5th 2002 - Swami v0.9.0pre1 released (yee ha!) --- Smurf Sound Font Editor (RIP) --- Sep 6th 2001 - Smurf v0.52.5 released May 5th 2001 - Smurf v0.52.1 released May 2nd 2001 - Smurf v0.52 released Jan 31st 2001 - Smurf v0.50.1 released Jan 1st 2001 - Smurf v0.50.0 released Sep 12th 2000 - Smurf v0.49.8 released Jul 5th 2000 - Smurf v0.49.5 released Mar 25th 2000 - Smurf v0.49.1 released Mar 20th 2000 - Smurf v0.49 released Dec 6th 1999 - Smurf v0.46 released Nov 8th 1999 - Smurf v0.45 released Sep 12th 1999 - Smurf v0.40 released, first public release! swami-2.2.0/README.OSX000066400000000000000000000130361361104770400141710ustar00rootroot00000000000000SWAMI-2.0 Installation on Mac OS X.5.5 (Leopard) ================================================ Ebrahim Mayat Josh Green Last updated: 9th October, 2008 Requirements: - fluidsynth - fink package distribution - X11.app, X11SDK.pkg, OpenGLSDK.pkg and QuickTimeSDK.pkg (Leopard Install DVD) - fink packages: cairo, gtk+2, gtk+2-dev, audiofile, flac, gettext, intltool, libtool14, libgnomecanvas2-dev, libxml2, pygtk2-py24-dev, pkgconfig, libart2, libglade2, pango1-xft2-ft219-dev, fftw3 and gtksourceview for example: "$ fink install gtk+2-dev" libinstpatch: configure && make && sudo make install: $ PKG_CONFIG_PATH=/usr/local/lib/pkgconfig ./configure "LDFLAGS=-L/usr/local/lib -L/sw/lib" "CFLAGS=-I/usr/local/include -I/sw/include" SWAMI: configure && make && sudo make install Building an app bundle with GTK-OSX =================================== BALATON Zoltan Last updated: 16th November, 2013 Resources: http://www.gtk.org/download/macos.php IMPORTANT! If you have packages installed from MacPorts, Fink, Homebrew or other repositories you have to make sure that these are not visible while building GTK-OSX. The easiest way is to create a new user for this and run everything while logged in as that user. Mixing GTK-OSX with packages from other builds will fail so make sure your path and environment is clean before continuing! 1. Build GTK-OSX (see: https://live.gnome.org/GTK%2B/OSX/Building) - Download and run gtk-osx-build-setup.sh - Set up your environment: $ cat <>$HOME/.profile DEVELOPER_DIR="/Volumes/10.7/Developer" PATH="$DEVELOPER_DIR/usr/bin":$PATH:"$HOME/.local/bin" export DEVELOPER_DIR PATH EOF $ . $HOME/.profile - Customise .jhbuildrc-custom for example: setup_sdk("10.6", sdk_version="10.6", architectures=["i386"]) moduleset=os.environ['HOME'] + '/custom.modules' module_autogenargs['cairo'] = '--enable-ft=no' skip=["gnome-doc-utils", "cups"] - Bootstrap jhbuild and build some packages $ jhbuild shell # make sure to enter the jhbuild shell first $ jhbuild bootstrap $ jhbuild build meta-gtk-osx-bootstrap $ jhbuild build meta-gtk-osx-freetype $ jhbuild build python $ jhbuild build meta-gtk-osx-core 2. Teach jhbuild about some more dependencies and build them - Edit $HOME/custom.modules to have something like this: - Build them: $ jhbuild shell # re-enter shell if exited from it, otherwise not needed $ jhbuild build libfftw3 $ jhbuild build fluidsynth $ jhbuild build libgnomecanvas $ jhbuild build libxml2 3. Now we could teach jhbuild to also build libinstpatch and swami like above if we built a release from tarballs but I simply built these by hand instead: $ jhbuild shell # always use the shell for anything needing stuff built by jhbuild $ cd $HOME/swami/src/libinstpatch $ ./configure --prefix=$HOME/swami/inst --build=i386-apple-darwin12.5.0 \ --host=i386-apple-darwin12.5.0 --target=i386-apple-darwin12.5.0 $ make && make install $ cd $HOME/swami/src/swami $ ./configure --prefix=$HOME/swami/inst --build=i386-apple-darwin12.5.0 \ --host=i386-apple-darwin12.5.0 --target=i386-apple-darwin12.5.0 \ PKG_CONFIG_PATH=$HOME/swami/inst/lib/pkgconfig:$PKG_CONFIG_PATH $ make && make install 4. Now we have everything built, let's make an app bundle - Install gtk-mac-bundler (see https://live.gnome.org/GTK%2B/OSX/Bundling) $ cd $HOME/Source $ git clone git://git.gnome.org/gtk-mac-bundler $ cd gtk-mac-bundler $ make install - After reviewing the swami.bundle file for correct paths build a bundle: $ cd $HOME/swami/src/swami/package/osxbundle $ jhbuild run gtk-mac-bundler swami.bundle $ ln -s Resources/lib/swami $HOME/swami/Swami.app/Contents/PlugIns swami-2.2.0/README.md000066400000000000000000000400061361104770400141150ustar00rootroot00000000000000# Swami - README ### Copyright (C) 1999-2019 Element Green and others http://www.swamiproject.org [![Build Status](https://dev.azure.com/tommbrt/tommbrt/_apis/build/status/swami.swami?branchName=master)](https://dev.azure.com/tommbrt/tommbrt/_build/latest?definitionId=2&branchName=master) _Note that this readme might be outdated_ ## 1. What is Swami? Swami (Sampled Waveforms And Musical Instruments) is a SoundFont editor. SoundFont files are a collection of audio samples and other data that describe instruments for the purpose of composing music. SoundFont files do not describe the music itself, but rather the sounds of the instruments. These instruments can be composed of any digitally recordable or generated sound. This format provides a portable and flexible sound synthesis environment that can be supported in hardware or software. ## 2. What happend to the Smurf SoundFont Editor? Nothing actually. Since I was already doing an entire re-code of Smurf I decided it would be good to change the name to give the program a fresh start and because I'm planning to make it more than just a SoundFont editor. Also the word 'Smurf' is copyrighted so I thought a change wise in this day and age of law suits. Swami does not yet completely replace Smurf in functionality, but it will. ## 3. License See [Copying](https://github.com/swami/swami/blob/master/COPYING). ## 4. Changes from Smurf Most of the changes have occured in the programming architecture. Much of this work has been done in preparation for really cool features (TM) :) The SoundFont editing code is now completely abstracted from the GUI in separate shared libraries making things like: scripting support, multiple client concurrent access to SoundFont objects and SwamiJam (networked semi-realtime composition with friends) more feasible. Most importantly things are much cleaner now so I don't go insane in attempts to add functionality. New features: - FluidSynth soft synth support (actually its required) which allows any OS supported sound card to be used and gives us modulators (real time effects) and routeable digital audio output for adding additional effects and for easy recording. - More operations work for multiple items. Including loading/saving/closing of multiple SoundFont files, loading multiple samples, and setting/viewing properties on multiple items. - Modulator editor for editing real time control parameters - Default toggle buttons for generator (effect) controls Things missing (as of this README): - Undo support - virtual SoundFont bank support - OSS AWE/SB Live! wavetable backend ## 5. Requirements Look at the INSTALL file for instructions on compiling and installing Swami and for more details on software requirements. Version numbers listed are what I developed Swami on, older or newer versions of the listed software may or may not work, but give it a try! And do let me know if you encounter any problems. Swami has the following requirements: - Linux, Windows and Mac OS X. Probably anywhere else GTK+ will run. - GTK+ v2.0 - FluidSynth v2.0 (software wavetable synthesizer) - libsndfile GTK homepage: http://www.gtk.org FluidSynth homepage: http://www.fluidsynth.org libsndfile homepage: http://www.mega-nerd.com/libsndfile ALSA homepage: http://www.alsa-project.org OSS homepage: http://www.4front-tech.com ## 6. Supported sound cards Any FluidSynth supported sound card (i.e. works under ALSA or OSS in Linux), since Swami uses FluidSynth which does all synthesis in software. A wavetable backend is planned for using hardware based SoundFont synthesizers like the SB AWE/Live! for those who don't want to use their precious CPU cycles :) ## 7. Features Current features include: - Loading of multiple SoundFont 2.x files *.SF2 - Saving of multiple SoundFont files - Copy Samples/Instruments/Presets between and within SoundFont objects - Load and export multiple audio sample files (WAV, AU, etc) - View/set multiple Preset, Instrument and Sample parameters - A GTK piano widget to play notes with computer keyboard/mouse - Wavetable loading of entire SoundFont - Piano MIDI controls (Pitch bender amount, volume etc.) Features provided by FluidSynth: - Flexible driver system that supports OSS, ALSA, LADSPA, Jack, Midishare, etc - Real time effects via modulators and C API ## 8. Future plans The following are in the works or planned: - Undo support (just haven't written a front end for it really) - Copy/Paste generator parameters - Graphical manipulation of generator parameters Was part of Smurf, not yet added: - Loading, saving and editing of virtual bank (*.bnk) files - Multiple undo/redo tree system, allowing for multiple redo "branches" - Sample cut support - Sample waveform generation - International language support (currently disabled until there are some updated translations, contact me if interested) ## 9. Troubleshooting drivers (or why does Swami crash on startup?) [Some of these switches haven't been enabled yet!] Some new command line switches were added to help with trouble shooting problems with Swami. Crashes experienced on startup of Swami are often caused by audio drivers. Type "swami --help" to get a list of usable switches. Since Swami, by default, tries to open the drivers on start up, a way to disable this behavior was added. "swami -d" will cause Swami to start, but drivers will not automatically be opened. Once started you can change your driver preferences (set certain ones to NONE) to try to determine which driver is crashing. Then issue a Control->"Restart Drivers" to cause the drivers to be re-opened. Swami v0.9.0pre1 Copyright 1999-2002 Josh Green Distributed under the GNU General Public License Usage: swami [options] Options: -h, --help Display this information -d Disable drivers (try if Swami crashes on start up) -c Ignore preferences and use factory defaults ## 10. Using Virtual Keyboard interface [Most of this is true, although some things haven't been implemented yet] The wavetable and piano interface have been changed in Smurf v0.52. Some of the new features include: * MIDI channel control (on toolbar, titled "Chan") Sets what MIDI channel the piano plays on. All other MIDI controls (bank, preset and MIDI controls on pop up menu) are remembered for each channel. * MIDI bank and preset controls (also on toolbar) Sets the current bank and preset for the selected MIDI channel. These are often changed automatically by the user interface when selecting items in the SoundFont tree, they can be changed manually as well. * Entire SoundFont loading Allows you to load an entire SoundFont. This is particularly useful to make a SoundFont available for sequencing with other programs. * Controls for changing how interface works with wavetable * Piano follows selection When enabled: virtual keyboard will "follow" the SoundFont tree selection. This will cause the selected item to be the one heard on the piano. If selected item is a Preset in a loaded SoundFont, then the piano will select the Bank:Preset of that item. Otherwise it is set to the Temporary Audible Bank:Preset (configurable from preferences, defaults to 127:127). By disabling this feature you can have more control over what is being played by the virtual keyboard. * Auto load temp audible When enabled: selected items in the SoundFont tree that aren't Presets in a loaded SoundFont, are automatically loaded into the wavetable device. They are mapped to a temporary Bank:Preset which is configurable from Preferences. Disabling this allows for faster editing, if one does not care to hear items. * Temporary audible - The temporary audible enables you to listen to components of a SoundFont that aren't directly mapped to a MIDI Bank:Preset. This is done by designating a Bank:Preset for temporary use. It defaults to 127:127 but can be changed in Preferences. When a non-Preset or a Preset that isn't in a loaded SoundFont is loaded (either from the "Auto load temp audible" option or manually from the "Wavetable Load" item on the right click menus), it is mapped to this temporary bank and preset number. ## 11. Creating Preset/Instrument zones To add zones to an Instrument hold down the CTRL key and select the samples you want to be added (SHIFT works too for selecting a range of items). Then "Right Click" the Instrument you want to add the samples to. Select "Paste" from the pop up menu. A zone will be created for each Sample (or Instrument zone) you selected. This same procedure can be applied to Presets using Instruments as zones. To create a "Global Zone", "Right Click" on the Preset or Instrument you want to create the zone under. Select "Global Zone" from the pop up menu. Global Zones are used to set "Default" generator (and modulator) parameters that the other zones don't already have set. ## 12. Using the sample viewer The sample viewer is used to change loop points for samples and instrument zones. Some things have changed in the sample viewer and probably will be changing again. The sample zoom/unzoom is now performed with the SHIFT key held down. Regular left mouse clicks are now used for sample selections for audio editing functions (currently only "cut"). Tips to using the sample viewer: Zooming IN/OUT Hold down SHIFT on the computer keyboard and click and hold the LEFT mouse button in the sample window, a white line will appear to mark your click, move the mouse to the left or the right to zoom into the sample. The distance you move the mouse from the original point of your click determines the speed in which the view zooms. If you then move the mouse to the other side of the line the view will unzoom. The RIGHT mouse button does the same thing, except the first direction you move the mouse unzooms the view. Selecting audio data Left click and drag to mark an area. An existing selection can be changed by holding down CTRL and Left or Right clicking to change the left or right ends of the selection respectively. ## 13. Undo system **Not enabled yet!** Swami has a rather flexible undo system. Many actions aren't currently undo-able, but will be implimented soon. Currently all actions relating to new SoundFont items, pasted SoundFont items, and deleted items are undo-able. The undo system is based on a tree rather than queue or list. This means that multiple changes can be easily tested. A traditional undo system is oriented as a list. Here is an example to help understand the Swami undo tree system compared with the traditional one. 1. You change some parameters related to the Modulation Envelope of an instrument 2. You don't quite like the changes, so you undo them 3. You try some other values for the same Modulation Envelope Lets say now you want to try the parameters in Step 1 again to compare to the settings in Step 3. In a traditional undo system you would not be able to do this because Step 3 would cause the "redo" information from Step 2 to be lost. Using a tree, multiple branches of "state" information can be stored. So rather than Step 3 "over writing" the redo info from Step 2, it would simply create another "branch" in the tree. Note: This was just an example of usage, but Swami doesn't support undo-ing of parameter changes yet. When just using the Undo/Redo menu items the undo system acts as a traditional list oriented undo system. The "Undo History" item on the Edit menu will bring up a dialog that lists previous actions. The dialog buttons available are Undo, Redo, Jump, Back, Forward, < (left arrow), > (right arrow). The current location in the state history is indicated by 2 greater than symbols ">>" in the left most column. Undo and Redo act just like the menu items, undo-ing (moving up the undo history) and redo-ing (moving down the undo history) the next/previous action from the current location. The "Jump" button will jump to the desired position in the undo history, causing actions to be undone/redone as necessary to realize the desired state. The Back and Forward buttons act like the traditional web browser function. Currently the last 10 positions in the undo history are remembered. This makes testing different settings easier. This isn't really useful yet as the currently undo-able actions aren't really ones you would wan't to test different settings with. But in the future when generator parameters are tracked in the undo history, this will be useful. The < (left arrow) and > (right arrow) are the second and third column headers of the history list. These columns are used to indicate other branches in the tree. Items that have other "sibling" branches will have a number in brackets (example: [ 1]) listed in the < (left arrow) and/or > (right arrow) column(s). The left arrow switches to older branches the right arrow to newer ones. Numbers in these columns indicate how many alternate older or newer branches (left arrow or right arrow respectively) are available. To switch to an alternate branch, select an item that has a number in one of the arrow columns. Click the corresponding arrow button at the top of the list. The selected item and all items below will be changed to reflect the new branch. ## 14. Virtual Banks **Not implemented yet in Swami!** Virtual banks allow you to make a SoundFont bank from many other SoundFont files. Swami currently supports loading and saving of the AWE .bnk format. This is a simple text file format listing each Preset and where it can be found SoundFont file:Bank:Preset and its destination Bank:Preset. **NOTE:** Make sure you set the "Virtual SoundFont bank search paths" field in Preferences. It should be a colon seperated list of where to find your SoundFont files. Example: "/home/josh/sbks/*:/tmp/sbks". Adding a '/*' to the end of a path will cause that directory to be recursively scanned (all sub directories under it). **Current limitations (will be fixed in future)** SoundFont files will not automatically be loaded with a virtual bank, so you'll have to load them by hand. Default SoundFont bank can't be cleared Can't edit virtual bank mappings #### Adding a Preset to a virtual bank Simply select and paste Preset items into the Mapping section of the virtual bank. #### Setting default SoundFont The default SoundFont sets the default Preset instruments. The Preset mappings override the default Presets. To change the default SoundFont simply paste a SoundFont item to the branch of the virtual bank. ## 15. SoundFont information, links and other resources I wrote an "Intro to SoundFonts" and its available on the Swami homepage http://swami.sourceforge.net. Its a general overview of what a SoundFont is. More information on the SoundFont standard can be obtained from www.soundfont.com. There is a PDF of the SoundFont technical specification at www.soundfont.com/documents/sfspec24.pdf. If you find that it has moved then look under the Resources section off of the soundfont.com home page (although it looks like you have to get a login to go there). Thanks to Frank Johnson at EMU for clarifying this. ## 16. Thanks Thanks to the following projects for making Swami possible: - FluidSynth (its what makes the instruments sound :) - gstreamer for gobject2gtk code and helpful examples of using GObject - Glade GTK interface builder - Gimp for graphics editing - Blender for render of campfire in desert Splash image - xmms code which I borrowed the multi selection file dialog modifications from - Piano to computer keyboard mapping inspired from soundtracker ## 17.
