Tarball containing D-Bus patched jack 0.117.0 is available here: http://nedko.arnaudov.name/soft/jack/dbus/ http://nedko.arnaudov.name/soft/jack/dbus/jack-audio-connection-kit-dbus-0.… http://nedko.arnaudov.name/soft/jack/dbus/jack-audio-connection-kit-dbus-0.… D-Bus modifications add optional autodetected support for the D-Bus based server control system. D-Bus is object model that provides IPC mechanism. D-Bus supports autoactivation of objects, thus making it simple and reliable to code a "single instance" application or daemon, and to launch applications and daemons on demand when their services are needed. * Simplified single thread model for control and monitor applications. Various D-Bus language bindings make it trivial to write control and monitor applications using scripting languages like Python, Ruby, Perl, etc.. * JACK has log file (~/.log/jack/jackdbus.log) that is available for inspection even when autoactivation happens because of first JACK application is launched. * There is real configuration file used to persist settings that can be manipulated through configuration interface of JACK D-Bus object. * Improved graph inspection and control mechanism. JACK graph is versioned. Connections, ports and clients have unique (monotonically increasing) numeric IDs. * High level abstraction of JACK settings. Allows applications that can configure JACK to expose parameters that were not known at compile (or tarball release) time. Currently there are some minor differences between jack1 jackdbus and jack2 jackdbus: * There is no parameter constraints support (no enums and no ranges) * No get client pid function (probably affects lash) * Settings file (in ~/.config/jack/) is conf-jack1.xml instead of conf.xml, because jack1 and jack2 settings and not really compatible. When configured with D-Bus support, jack_control is installed. jack_control is simple commandline interface for jackdbus. Other tools that can communicate with JACK through D-Bus: * LADItools (tray icon, configuration, etc.) * Patchage (and lpatchage too) * LASH 0.6.x (may not work properly with jack1 jackdbus implementation) -- Nedko Arnaudov <GnuPG KeyID: DE1716B0>

[LAA] [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++.

by W.Boeke

BigBand is a program to compose real music for real musicians. If you are interested then please visit: members.chello.nl/w.boeke/bigband/index.html BigBand should be easily portable to different Linux versions as it is built using only the SDL libraries for graphics and sound. Kind regards, Wouter Boeke

[LAA] FluidSynth 1.1.0 "A More Solid Fluid" released

by josh＠resonance.org

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!
