Hi I have this running fine in ubuntu now, but have had problems. Have you tried to start it with an alsa oss wrapper? In ubuntu: sudo aptitude install alsa-oss Then run aoss java -jar improvisor.jar Else it might be that the java version is not the newest from sun or that t doesn't access the bank correctly. Hope you figure it out - the program is awesome!

Greetings, You'll have problems with JavaSound if your soundcard has no integral mixer. JavaSound only looks for an OSS-compliant device, which may be why GR's alsa-oss installation worked for him.

It has to do with connecting raw MIDI with a sequencer like timidity: Step 1: sudo modprobe snd-virmidi Step 2: timidity -iAqqq -B8,8 & # don't know if the -B8,8 is really necessary Step 3: connect the first VirMIDI port to the first Timidity port (I use qjackctl and the ports are under the ALSA tab in the Connections window) Step 4: In Impro-Visor, select the first VirMIDI port for output (or whichever one you connected to Timidity in Step 3). Play and enjoy! Google "timidity virmidi" to find several pages describing various aspects of this, including how to use aconnect to accomplish Step 3. Good Luck! Joel
