A simple test would be to launch qjackctl and look at
the connect
panel's MIDI
tab - if you don't see anything there, then MIDI isn't working.
in qjackctl I have 62:Midi Through as a parent and 0:Midi Through
Port-0 as child in both readable and writable clients.
You should already have:
snd-seq-midi
as the first entry in /etc/modules (?). In the past I've had to add:
snd-mpu401-uart
to that list in order to get it working. Check what your soundcard uses.
snd-seq-midi is one of the loaded modules. I have noticed that
snd-mpu401-uart is listed in aadebug. I'll try adding it to
/etc/modules. In the meantime, what I'm looking for is a simple test
program that when I press on a key from the keyboard, something lights
up or sounds to tell me that it's connected and working in some fashion.
