:) Fortunately, I was wrong !!
Midi playback works! The MOX wasn't configured in the right midi channel.
$ aconnect -iol

1 'Announce '
client 14: 'Midi Through' [type=kernel]

$ aplaymidi -p 20:0 mutopia_sample.mid
sounds fine in the MOX.
Midi recording works!

good!
Audio playback works! I didn't choose the right device.

At this point, the only thing I'm sure is the main problem is my
