MIDI Problems with QjackCtl February 20, 2006

Posted by oktyabr in debian, hacking, linux, make music, realtime, software.

I get the following error:

Could not open ALSA sequencer as a client.

MIDI patchbay will be not available.

In the message console I get the same message followed by the line:
ALSA lib seq_hw.c:455:(snd_seq_hw_open) open /dev/snd/seq failed: No such file or directory.

I’m still too much of linux n00b to fully understand what that means or how to go about fixing it. The real world result is that I have no MIDI capabilities when this happens. I’m running a USB MAudio Midisport 4×4 which runs perfectly in Demudi 1.2.1 and is at least properly detected in Kanotix (another debian). Google seems to suggest I need to rebuild my ALSA libraries but I have yet to find a well written HOWTO that might fix this problem.

Have any clues?”


/dev/snd/seq failed: No such file or directory

solution: modprobe snd-seq
