The following is my opinion, and of course everyone is free to argue otherwise. ;-) When "planning" a project, I prefer to make an Assessment of the resources that I have available first, because I somehow like to be realistic about what really "can" be done instead of building castles out of air and then being disappointed that it did not work out. So, this "Project" seems to be about "Code", programming code and such. So, while there is certainly a lot of code already out there that can be reused, someone has to fit it together and someone has to fill in the missing parts. So this project will involve coding. So we need "Coders". This is how open source projects work, they need coders. There are many people with ideas, but someone has to code it and generally, those people are a scarce resource. So, in planning this stuff the first thing to find out is who are the coders, and what are they willing to do. Making big plans and then expecting outsiders to jump in and start coding is an approach that has proven not to work, at least as far as my experience goes. Maybe at one point outsiders will come and start contributing, but for that to happen, a solid core is needed, something that is of value to contributors. And btw. I also believe that making plans that reach too far into the future are very, very risky, especially if one relies on volunteers. Better make a small proposal for a well defined problem, for which a solution is immediatly useful. Then try to get it solved as fast as possible, before people loose interest, and then try to "infect" as many peer groups as possible with the solution to create an "eco-system" where the solution can sustain itself. Then fit that part into the big picture, and move on to the next little puzzle part. So, I am volunteering to do stuff, who else is?

This looks like an opportunity to beef up audio side of things as well as foster development of another powerful foss multimedia software. See below for more info.

Why Cinelerra is the most powerfull free software for video editting we have nowadays. Although it has many resources and that it is far more advanced than any other Open Source video software, its development is very slow and has no sponsor. Its main developer, Heroine Warrior, do not mantain a SVN or a mailing list. The last official release was last july and there is no sign of a upcoming version of cinelerra. They usually publish a new release every six month or so but do it only for their own needs and do not talk with the community much. Few developers mantain a fork called "Community Version". All out of volunteer work they mantain a SV a mailing list and an online wiki. They also fix some bugs and add some features to the code. This desorganized development results in a mess. There is no official stable release and package for the distributions, and cinelerra is now known as very hard to install and unstable software (although it got really better last year). Also, first contact with cinelerra is usually disappointing because of a not well resolved interface and also because of big flaws it has on some funcionalities. With all that said, it happens that we have a software that is, at the same time, powerfull enough to do any kind of editing, but weak enough to have very basic issues of usability. And the feeling all advanced users have is: We are pretty close to have high standard software! To learn more about the mess, take a look at this page: http://cv.cinelerra.org/about.php Many of the actions described on this plan are already been done by many people, but in a rather heroic way. If this people got motivated, organized and _paid_, cinelerra would increase its quality dramatically in a short period of time. The Plan 1. Get the community together The community of developers today is very small and spread, and cinelerra has no road map. First thing to do is gather this people to discuss about the future of cinelerra, identify the main flaws and its solution, make a plan to organize the place and set up for new features. Cinelerra needs a project leader, an interface designer, and more people with defined roles that should be choosen on this meeting. Developers of other softwares are also welcome. Cinelerra is, so far, the only video free editing video editing software with professional approach, but it could share a lot of things with other software, such as effects, for example, that shoul be usable in any video software, just like we have LADSPA for audio. There is already a video effect standar called Frei0r that cinelerra does not support. 2. Diagnostics Cinelerra code is not very well documented, so few people have the idea of how tuff is to deal with it. Second step is to see what must be done so we can invite more people to colaborate with the code. Documentation, refactoring, etc. It also has to work on the API so other people can write plugins and effects. In other words, lots of work that are a pain in the ass but has to be done in order to advance properly. And passion has a limit. There must be people getting money to work on that. 3. Make a plan Based on the diagnostics and on researches with users and other video editing tools, define how cinelerra will look and act in a not so distant future. With that goal in mind, make a reasonable plan to make it happen. 3. Set up a core development team No secret here. Few people dedicated to make it happen, including an interface designer. 4. Bounties The core team can offer bounties for parts of the job they choose. This will attracat more developers to the community. 5. Attract contributors Mantain a nice looking website, a wiki, tools for easy translation of the interface and of the online documentation, etc. are goos strategies to attract people to contribute. Its also important to find people to package the software for different distributions. -- leogermani.pirex.com.br leogermani.estudiolivre.org ________________________________ Lista de Discussão do Estúdio Livre portal colaborativo -> http://www.estudiolivre.org/ sobre esta lista -> http://lists.riseup.net/www/info/estudiolivre -- Fabianne Balvedi GNU User #286985 http://fabs.estudiolivre.org "As contradições mais agudas da vida humana não foram feitas para serem solucionadas, mas vividas com plena ciência de seu carater paradoxal."

MidiShare problem on AMD64

by Dave Phillips

Greetings, I'm trying to get IRCAM's Open Music 5.2.1 running here, but I'm having various difficulties. For now, I'll focus on this one: I'm trying to build MidiShare (it's required by OM) on my 64-bit machine (64Studio), and I've got this far : make -C kernel make[1]: Entering directory `/home/dlphilp/src/openmusic/midishare-1.91-linux2.6-src/src/linux/kernel' for x in atomic/lffifoIntel.c atomic/lflifoIntel.c Clients/msAlarms.c Clients/msAppls.c Clients/msConnx.c Clients/msFilter.c Clients/msMail.c Clients/msTasks.c Clients/msXmtRcv.c Kernel/msHandler.c Kernel/msInit.c Kernel/msSmpte.c Kernel/msTime.c Memory/msEvents.c Memory/msFields.c Memory/msMemory.c Memory/msSeq.c Sorter/msSorter.c Drivers/msDriver.c; do ln -sf ../../common/$x `basename $x`; done make modules -C /usr/src/linux SUBDIRS=/home/dlphilp/src/openmusic/midishare-1.91-linux2.6-src/src/linux/kernel make[2]: Entering directory `/usr/src/linux-headers-2.6.21-1-multimedia-amd64' CC [M] /home/dlphilp/src/openmusic/midishare-1.91-linux2.6-src/src/linux/kernel/msLoader.o /home/dlphilp/src/openmusic/midishare-1.91-linux2.6-src/src/linux/kernel/msLoader.c:1: sorry, unimplemented: code model kernel not supported in PIC mode /home/dlphilp/src/openmusic/midishare-1.91-linux2.6-src/src/linux/kernel/msLoader.c:1: error: code model ‘kernel’ not supported in the 64 bit mode make[3]: *** [/home/dlphilp/src/openmusic/midishare-1.91-linux2.6-src/src/linux/kernel/msLoader.o] Error 1 make[2]: *** [_module_/home/dlphilp/src/openmusic/midishare-1.91-linux2.6-src/src/linux/kernel] Error 2 make[2]: Leaving directory `/usr/src/linux-headers-2.6.21-1-multimedia-amd64' make[1]: *** [all] Error 2 make[1]: Leaving directory `/home/dlphilp/src/openmusic/midishare-1.91-linux2.6-src/src/linux/kernel' make: *** [kernel] Error 2 Has anyone ever compiled MidiShare for a 64-bit machine, and if so, how ? I'm using Albert Graef's patches for MidiShare 1.91, but they don't address the 64-bit problem. Is MidiShare even maintained anymore ? I had troubles compiling 1.91 on my 32-bit box too, and since it's required for Open Music I'd like to figure out how to build it on both boxes here. Some time ago I did write to GRAME re: MidiShare development but received no response. Any suggestions ? Best, dp

NtED is the real WYSIWYG music score (updated)

by Roque Morel

Hi. My name is Roque Morel NtEd is the easiest music score I`d saw. Only three steps: ./configure, make, make install and it`s ready to use. Rare dependencies and libraries does not need it. Where another ones failed on my favor distro, NtEd got no any trouble. Commands are very easy too and it works very well with Timidity or QJackctl+QSynth. It supports tuplets and others, up to 4 voices per staff, 5 lyrics lines, three clefs, exports to GS and MIDI. Very important things? It`s a real page view music score for Linux, it`s easy for musicians, it is not a too much MB program, it`s nice to work and the more important point in music: it`s a What You See Is What You Get music score and is stable. Necessary things? Slurs, bow signals for strings instruments, more clefs and other musical signs. For Mandriva`s users as me, there are some packages in cooker repositories I asked by bugzilla ftp://distrib-coffee.ipsl.jussieu.fr/pub/linux/MandrivaLinux/devel/cooker/cooker/media/contrib/release/nted-0.13.0-1mdv2008.1.i586.rpm ftp://distrib-coffee.ipsl.jussieu.fr/pub/linux/MandrivaLinux/devel/cooker/x86_64/media/contrib/release/nted-0.13.0-1mdv2008.1.x86_64.rpm Author URL: http://vsr.informatik.tu-chemnitz.de/staff/jan/nted/nted.xhtml downloads source: http://vsr.informatik.tu-chemnitz.de/staff/jan/nted/nted-0.16.0.tgz Debian packages: http://vsr.informatik.tu-chemnitz.de/staff/jan/nted/nted-0.16.0.deb I forgot to comment on the matter musicXML version 0.16.0 Enjoy it

[ANN] lv2vocoder plugin version 1 released (Happy robots use Linux and LV2!)

by Nedko Arnaudov

Perhaps you don't know what a vocoder is, but I'm sure you have heard one before. Vocoders are often used to add a robotic effect to vocals in music. Project homepage: https://gna.org/projects/lv2vocoder Get tarball from here: https://gna.org/files/?group=lv2vocoder This code is based on version 0.3 of LADSPA plugin created by Josh Green. LADSPA plugin created by Josh Green is basically an adaption of Achim Settelmeier's Vocoder program to LADSPA. Achim Settelmeier's Vocoder programs and Josh Green's LADSPA plugin, can be found at: http://www.sirlab.de/linux/ Happy robots use Linux and LV2! -- Nedko Arnaudov <GnuPG KeyID: DE1716B0>

[ANN] zynadd plugin version 1

by Nedko Arnaudov

The zyn project main goal is to extract synth engines from ZynAddSubFX and pack them in LV2 plugin format. Resulting plugin(s) are heavily based on work made by Nasca Octavian Paul. Project goals: * Port ZynAddSubFX synth engines to LV2 * Fix some inherit issues preventing hard-realtime mode of operation, causing clicks sometimes (memory allocation/sleep in audio process context) * Make synth engines reusable in source form * Make all synth engines parameters controlable on the fly (as opposed to original "parameter change takes effect on next note on" strategy) Currently only zynadd (ADDsynth) is ported. Not all parameters are exposed yet. Nevertheless plugin produces sound/noise and has enough parameters exposed to tweak sound generation at great extent. You need lv2dynparam plugin library to compile the plugin.

[ANN] zynjacku version 1 released

by Nedko Arnaudov

zynjacku is JACK based, GTK (2.x) host for LV2 synths. It has one JACK MIDI input port (routed to all hosted synths) and one (two for stereo synths) JACK audio output port per plugin. Such design provides multi-timbral sound by running several synth plugins. zynjacku is a nunchaku weapon for JACK audio synthesis. You have solid parts for synthesis itself and you have flexible part that allows synthesis to suit your needs. You need slv2 library and lv2dynparam host library to compile zynjacku.
