Current setup: PPC G5, Ubuntu studio 12.04, Focusrite sapphire soundcard through USB.
Working fine through qjackCtl: Audacious midi, Audiocity (recording and playback), Ardour
No sound: Rosegarden, Tuxguitar, timidity
I suspect this is a Midi issue. My objective here is to get Tuxguitar to work, I just used Rosegarden to find a pattern.
My current output in tuxguitar: Realtime sequencer / Gervill; (already tried the others, they don't work either)
Regarding tuxguitar plugins, the only one I see related to Midi is "Fluidsynth settings" where the soundfont points is FluidR3_GM.sf2, audio driver is alsa, 16bits, 64, 16. Java is 1.6.
The Java Souns API plugin is activated, and configured to "use default soundbank".
When I check Audacious, output plugin is Jack, and the Amidi-Plug preferences show 2 backends available, ALSA and Fluidsynth, with oundfonts= FluidR3_GS and _GM.
