pyliblo is a Python wrapper for the liblo OSC library. It supports almost the complete functionality of liblo, allowing you to send and receive OSC messages using a nice and simple Python API. New features in version 0.6: * added support for bundles and timestamps * support additional OSC data types (midi, timetag, symbol, true/false/nil/infinitum) * alternative way for registering callback methods, using nifty Python decorators Get it here: http://das.nasophon.de/pyliblo/ Cheers, Dominic

knowing JACK

by Dave Phillips

Greetings: Some time ago I wrote a rather lengthy user-level introduction to JACK. It was published in a German Linux magazine, and I'd now like to put the original on the Web. However, it surely needs updated, so I've placed its current condition on-line here : http://linux-sound.org/knowing-jack.html At this time I'm looking for corrections and additions to the main text. I've purposefully left out the screenshots, I'll update them myself after the text is up to date. I'm not using FreeBob or JackMIDI and would apprciate any information readers think should go into the article. Please advise if any information regarding the QJackCtl audio options needs changed. Users often wonder what all those checkboxes actually do, and I'd like to give them the right info. Btw, this artice is *not* planned for publication again, and I'll happily place it under a CC license if desired by the community. If acceptable I'd like it to go on the linuxaudio.org site. Feel free to respond to the lists or directly to me. Best, dp

[LAU] PHASEX-0.10.2

by William Weston

The [P]hase [H]armonic [A]dvanced [S]ynthesis [EX]periment, version 0.10.2 is ready for download (source tarball and FC6 RPMs) at: http://sysex.net/phasex/ This release contains many fixes, most notably better support for older GTK versions. PHASEX now works with GTK2 versions as low as 2.4.x, which should help most of the build issues on older distros. Here's everything from the Changelog for this release: * Fixed typos and omissions in parameter help file. * Improved error handling and reporting in jack.c. * Fixed JACK thread shutdown. * Added Pete Shorthose's patch for saving memory with a single knob anim. * Added Lars Luthman's patch for improper style handling in gtkknob.c. * Fixed knob centering on middle click drag events. * Cleaned up style and whitespace in gtkknob.c, added boilerplate. * Added current midimap file to saved settings. * Fixed build and runtime problems with GTK versions 2.4 to 2.8 * Fixed invalid setting of patch modified flag on startup. * Updated error message for unhandled ALSA MIDI errors. * Fixed passing of debug flags in configure.ac. * Fixed detection of functions in libm. * Added install of phasex.desktop to Makefile.am. * Fixed uninitiailized varibable warnings in midi.c. * Fixed missed internal update on boolean parameters first switching to zero. * Removed dead update_widget_val() in callback.c. * Disabled engine side of audio ringbuffer locking (easier on JACK). * Changed name of ALSA MIDI sequencer input port for readability. * Added project roadmap. Special thanks go to Pete Shorthose and Lars Luthman for your patches to the gtkknob code, and to the rest of you for offering incredible feedback, especially on the build issues and ALSA/JACK startup issues.

There are various sf2 and .gig resources all over the web, alas most of 'em with a dubious license. given the recent number of "soundfont" posts to LAU, i concur that linuxaudio.org should devote some resources on the subject. I've started a page on our tentative wiki: http://apps.linuxaudio.org/wiki/soundfonts to collect resources and gather ideas; feel free to continue discussion on the mailing lists: convergence of free & open sound-font collections is overdue and we can use any hand available ;) - even so more when ardour MIDI track newbies will start to ask for soundfonts in the near future. robin -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFGSynMeVUk8U+VK0IRAo/fAJ4idiX0hMPWIE7uulcmfPjSu+dZ/wCfbZP8 x/iOO8B66Zymu+Z8C6GznVk= =UZ27 -----END PGP SIGNATURE-----
