Before we try to rule out wrong MIDI connections or a missing soundfont, we should start with a command line to start jackd. Run aplay -l in a terminal and post the output. It will show "card 0", "card 1" ... "card n". Then in a terminal test running card=0; killall -9 jackd && jackd -dalsa -dhw:$card -r48000 -p1024 -n2 after that start QjackCtl, Qsynth and Qtractor and at last connect the MIDI and audio IOs. If it shouldn't work close Qtractor, Qsynth and QjackCtl and run card=1; killall -9 jackd && jackd -dalsa -dhw:$card -r48000 -p1024 -n2 after that start QjackCtl, Qsynth and Qtractor and at last connect the MIDI and audio IOs. If it shouldn't work close QjackCtl and continue ... If it never should work and there should be failure messages, then post those messages. If it shouldn't work, but there should be no failure messages then report back and we'll focus on MIDI connections and soundfonts. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
