OK, this is what is confusing me. When I do as above, I get this:
client 0: 'System' [type=kernel]
0 'Timer '
1 'Announce '
client 14: 'Midi Through' [type=kernel]
0 'Midi Through Port-0'
client 16: 'FastTrack Pro' [type=kernel]
0 'FastTrack Pro MIDI 1'
client 20: 'Virtual Raw MIDI 1-0' [type=kernel]
0 'VirMIDI 1-0 '
client 21: 'Virtual Raw MIDI 1-1' [type=kernel]
0 'VirMIDI 1-1 '
client 22: 'Virtual Raw MIDI 1-2' [type=kernel]
0 'VirMIDI 1-2 '
client 23: 'Virtual Raw MIDI 1-3' [type=kernel]
0 'VirMIDI 1-3 '
In /dev, udev gives me stuff like:

crw-rw---- 1 root audio 14, 29 2007-10-02 09:17 /dev/amidi1

I can't make sense out of which of those ALSA (QJACKCtl) ports maps to which device in the /dev tree! And, specifically, which one is /dev/midi, to which the Atari/steem is connected? That's really the only missing peice for me: where do those wires lead to exactly?
