Greetings list, I came across Dave Philip's article on midi arpeggiators ( http://www.linuxjournal.com/content/linux-arpeggiators-part-2) a few minutes ago. Dave recommends using either klick or tapstart to send external clock signals to arpage. I've installed both, but I can't find any way to send the output of klick into arpage. I'm obviously doing something very noobish and obviously wrong, anyone care to enlighten me? Thanks, Andrew.

chino-0.01 - first release

by David Adler

chino is mainly a bash script generating scripted sessions around seq24, yoshimi, pd and ardour. It is rather specialised in its scope, only yoshimi is used for sound generation. However, I prefer just adding a few apps manually to the generated scripts towards hand editing from scratch. Be warned, this is my very first program. Any kind of helpful feedback is very much appreciated. Tested with jack1 and ardour2, 32 and 64 bit. url: http://chino.tuxfamily.org/ tarball: http://download.tuxfamily.org/chino/chino-0.01.tar.bz2 AUR package: http://aur.archlinux.org/packages.php?ID=37192 greetings, d

Reflections of... DSSI and OSC

by Ken Restivo

Is there some kind of reflection capability in DSSI so that I can discover which OSC parameters are available for a synth? It's time to trot out Monosynth again, and this time I'd like to customize its MIDI controls, and I usually do this via a Python script that converts MIDI to OSC. But somehow I have to find out what parameters are exposed via OSC first. -ken

Anyway, no PA here. Don't need it to play MP3s. Don't need to hear stupid, pointless audio notifications from desktop software, either - on ANY OS I use. -- David gnome(a)hawaii.rr.com authenticity, honesty, community

by rosea.grammostola

(sorry for cross posting) I also have problems with ICE1712 based card. I spoke with Lennart about it. It's an known problem in ALSA, but we need someone who wants to fix this in ALSA. More info here: http://pulseaudio.org/ticket/624 These cards where always recommended for Linux in the lower price range. It's sad that they don't work out-of-the-box anymore... \r On Sat, 2010-05-08 at 12:50 -0700, Niels Mayer wrote: > seen in LAU: > > > https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/178442 > > > > http://www.mail-archive.com/pulseaudio-discuss@mail.0pointer.de/msg01082.ht… > gives a solutiion (see all messages). > > > http://www.mail-archive.com/pulseaudio-discuss@mail.0pointer.de/msg01155.ht… > gives the cause: > PA knows no suitable default channel map for devices that have > 10 > channels (in contrast to 1, 2, 4, 5, 6, 8).

History of the Olympic livecoding games at the LAC

by nescivi

Hi, for reference, here's a history of what happened during the first Olympic (SuperCollider) livecoding games at the LAC in Utrecht: http://www.nescivi.nl/?p=166 "Concept of the Olympic Games livecoding environment Going back to the original Olympic thought of participating is more important than winning, and drawing on ancient Greek tradition of consulting an Oracle to find a new path in life, or gain advice on the path one has taken… The OlympicGames provide a collaborative, playful competitive livecoding environment, where participants are given alternating a set of UGens to write a SynthDef with, or a set of Pattern elements to write a Pattern with. The executed code of all participants is visible, both to the audience (by displaying its screen with a projector) and to all participants. So every participant can modify code others have come up with." Thanks to Alberto and Julian for the wonderful Republic Quark, and for the original Oracle function... :) Sincerely, Marije
