I have a CME UF5 MIDI keyboard (USB), which mostly works fine with ALSA.
However if I move the Master Volume slider I stop getting MIDI events - I have to disconnect the snd_seq port and reconnect it to get MIDI events working again.
Is there any error message in the system log when this happens?
No, I don't think so. You mean /var/log/messages?
Also, I wanted to try the rawmidi test app, but what would the device ID be?
Have a look at the output of "amidi -l".
Thanks. I've got rawmidi working, and it doesn't seem to have a problem with the master volume slider. So I guess it is an alsa-seq issue.
If I move the slider I get this in rawmidi (4 lines for each increment):
read f0 read 01 read 7f read 7e
read f0 read 01 read 7f read 7d
Are they valid MIDI messages?
