[ANN] Composite - New project for live audio sequencing

by Gabriel M. Beddingfield

I have started a new project called Composite, which is planned to be a sequencer for live-performance sequencing, sampling, and looping. One might say that it will be like Ableton Live. It will be an LV2 host for synths and effects, and will have a built-in sampler (which will probably be an LV2 plugin). At this time, the project is in the planning stages.[1] Anyone who is interested is invited to join the mailing list and share your thoughts and opinions -- especially as it relates to UI and workflow.[2] Links...... Project: http://gabe.is-a-geek.org/composite/ Mailing List: http://groups.google.com/group/composite-dev Code: http://gitorious.org/composite Specs (WIP): http://gabe.is-a-geek.org/composite/specification.html FAQ: http://gabe.is-a-geek.org/composite/faq.html Thanks especially to Patrick Shirkey for stirring things up. Peace, Gabriel CC: LAU, LAD, LAA, Composite-Dev [1] Strategy: Create a published spec. of what we want to accomplish, and then get after it. There is currently no code, but we plan to steal as much as we can. [2] However, these will probably *not* change: + Will be monolithic. Let's not start a monolithic vs. modular debate. + Will use Qt and C++.

On behalf of the FluidSynth development team, I'm happy to announce the release of FluidSynth 1.1.0 "A More Solid Fluid". This is the result of a 6 month development cycle and is the most significant release since 1.0.0. FluidSynth is a software wavetable synthesizer based on the SoundFont 2 specification. http://fluidsynth.resonance.org New features and changes: * Extensive work on making FluidSynth more thread safe, resulting in better stability. * Audio file rendering for MIDI to audio file conversion, faster than realtime (#15). * Optional libsndfile support for file rendering in different audio file formats (wav, flac, ogg vorbis, etc) (#30). * Audio and MIDI are synchronized for MIDI file playback. * Server can be specified for Jack audio and MIDI drivers. * Jack audio and MIDI is now synchronized (when same Jack server used). * MIDI file playback is now timed correctly, even with large audio buffer sizes. * Fixed issue with missing percussion in MIDI files caused by very short notes, using synth.min-note-length setting (#1). * Improved support for MIDI tuning standard, including SYSEX support and realtime tuning activation. * Multi-core support for utilizing multiple CPUs for synthesis or increasing speed of file rendering. * Voices for a note-on event are started synchronously (#46). * TCP/IP shell server support for windows (#20). * Improved settings output (-o help) (alphabetically sorted and string options listed). * Audio driver (-a) and MIDI driver (-m) options now accept "help" and list available options (#41). * Added audio.realtime-prio and midi.realtime-prio for controlling realtime scheduling of some audio and MIDI drivers. * Default priority levels of audio and MIDI threads set to 60 and 50 respectively. * All yes/no string boolean settings converted to integer toggle settings (with backwards compatibility). * glib is now a required dependency. * Updated README-OSX * Added "voice_count" shell command for getting current number of active voices. New command line options: -F, --fast-render=[file] -T, --audio-file-type -O, --audio-file-format -E, --audio-file-endian New or changed parameters: * Audio file output settings: audio.file.endian, audio.file.format, audio.file.name, audio.file.type, audio.sample-format * Realtime scheduling settings: audio.realtime-prio, midi.realtime-prio * Jack settings: audio.jack.server and midi.jack.server * Other settings: player.reset-synth, player.timing-source, synth.cpu-cores (experimental), synth.min-note-length Bug fixes and minor changes: * Fixed enabling of high priority scheduling in many audio drivers. * Fixed bank selection logic * Build fixes for mingw and VC++ builds on Windows * Fix default values (after MIDI reset) to be more consistent with MIDI spec (#29). * Removed VintageDreamsWaves-v2.sf2 since it wasn't under a free license. * Solaris build fix (#52) * Implemented fluid_player_set_loop (#33) * Fixed scaletune error (#26) * Fixed synth reset between songs (#31) * Fixed pitch bend error in Windows MIDI driver (#54) * Skip remaining track data in MIDI file after EOT (#53) * Bug fix in MIDI router where mutex was left locked with MIDI system reset message. * Help command now shows list of topics instead of General help. * Fixed non-blocking in alsa_raw, alsa_seq and OSS MIDI drivers. * Fixed segfault on config file load (#45). Changes affecting developers: * Developer API docs overhauled and now very complete. * Lots of code cleanup in fluid_synth.c, fluid_chorus.c, fluid_reverb.c and fluid_chan.c. * Improved use of settings hints for all settings. * char * arguments changed to const char * for many function prototypes. * Many new API functions. See "Whats new in 1.1.0?" section in developer API documentation for more details: http://fluidsynth.resonance.org/docs/api/index.html#NewIn1_1_0 Contributors ------------ Josh Green David Henningsson Pedro Lopez-Cabanillas Ebrahim Mayat And many others!
