Hi
I got the Audiotrak MIDI-MATE and it works stright out of the box. Great!
Now the next problem is that my usb devices seem to show up different
depending on the order they are inserted and/or the physical order in
which they are connected to my usb-bus.
I have:
2 x Evolution MK-249C usb midi keyboards
1 x Audiotrak MIDI-MATE usb midi interface
1 x Edirol UA-1A usb soundcard
1 x onboard i810 soundcard
An example of the confusion:
a) I plug in the devices in this order: Evolutions, Audiotrak, Edirol
and get:
[atte@aarhus ~]$ aconnect -i
client 0: 'System' [type=kernel]
0 'Timer '
1 'Announce '
client 80: 'Virtual Raw MIDI 2-0' [type=kernel]
0 'VirMIDI 2-0 '
client 81: 'Virtual Raw MIDI 2-1' [type=kernel]
0 'VirMIDI 2-1 '
client 82: 'Virtual Raw MIDI 2-2' [type=kernel]
0 'VirMIDI 2-2 '
client 83: 'Virtual Raw MIDI 2-3' [type=kernel]
0 'VirMIDI 2-3 '
client 88: 'MK-249C USB MIDI keyboard - Rawmidi 3' [type=kernel]
0 'MK-249C USB MIDI keyboard MIDI '
client 96: 'MK-249C USB MIDI keyboard - Rawmidi 4' [type=kernel]
0 'MK-249C USB MIDI keyboard MIDI '
client 104: 'XP MIDI mate - Rawmidi 5' [type=kernel]
0 'XP MIDI mate MIDI 1'
b) I plug in in this order: Edirol, Audiotrak, Evolutions and get:
[atte@aarhus ~]$ aconnect -i
client 0: 'System' [type=kernel]
0 'Timer '
1 'Announce '
client 80: 'Virtual Raw MIDI 2-0' [type=kernel]
0 'VirMIDI 2-0 '
client 81: 'Virtual Raw MIDI 2-1' [type=kernel]
0 'VirMIDI 2-1 '
client 82: 'Virtual Raw MIDI 2-2' [type=kernel]
0 'VirMIDI 2-2 '
client 83: 'Virtual Raw MIDI 2-3' [type=kernel]
0 'VirMIDI 2-3 '
client 88: 'XP MIDI mate - Rawmidi 3' [type=kernel]
0 'XP MIDI mate MIDI 1'
client 96: 'MK-249C USB MIDI keyboard - Rawmidi 4' [type=kernel]
0 'MK-249C USB MIDI keyboard MIDI '
client 104: 'MK-249C USB MIDI keyboard - Rawmidi 5' [type=kernel]
0 'MK-249C USB MIDI keyboard MIDI '
c) Same physical order in the hub as b), but now I simply pull out and
reinsert the hub:
[atte@aarhus ~]$ aconnect -i
client 0: 'System' [type=kernel]
0 'Timer '
1 'Announce '
client 72: 'XP MIDI mate - Rawmidi 1' [type=kernel]
0 'XP MIDI mate MIDI 1'
client 80: 'Virtual Raw MIDI 2-0' [type=kernel]
0 'VirMIDI 2-0 '
client 81: 'Virtual Raw MIDI 2-1' [type=kernel]
0 'VirMIDI 2-1 '
client 82: 'Virtual Raw MIDI 2-2' [type=kernel]
0 'VirMIDI 2-2 '
client 83: 'Virtual Raw MIDI 2-3' [type=kernel]
0 'VirMIDI 2-3 '
client 88: 'MK-249C USB MIDI keyboard - Rawmidi 3' [type=kernel]
0 'MK-249C USB MIDI keyboard MIDI '
client 96: 'MK-249C USB MIDI keyboard - Rawmidi 4' [type=kernel]
0 'MK-249C USB MIDI keyboard MIDI '
How do I control which order devices appear in? I would appreciate an
explanation that I (hopefully) understand over simply "put this in your
/etc/something".
BTW: I have looked at this before (before getting the Audiotrak) and
although I didn't understand how this list helped me out. So I have the
following (that I modified slightly after trying to solve the confusion
mentioned in this posting):
------------
[atte@aarhus ~]$ more ~/.asoundrc
# i810 onboard soundcard
pcm.onboard {
type hw

}
# edirol ua-1a audio interface

ctl.usb-audio {

}

Should also mention that this is on debian/unstable with kernel 2.6.9
