I just downloaded, patched and installed
2.6.16.5-rt14. Works fine, but
for the first time in my life have 'Midi Through' gotten client number
14, my evolutions keyboards are 24 and 28
The client numbering scheme was reorganized in ALSA 1.0.11rc1 because
there were too many unused reserved numbers and not enough free numbers
for more than eight cards.
The numbering scheme will not change again in the foreseeable future.
Solution?
Programs should use client names instead of client numbers.
For example, given the following ports:
$ aplaymidi -l
Port Client name Port name
14:0 Midi Through Midi Through Port-0
14:1 Midi Through Midi Through Port-1
20:0 MPU-401 UART MIDI MPU-401 UART MIDI
24:0 Yamaha DS-1E (YMF754) MIDI Yamaha DS-1E (YMF754) MIDI
25:0 OPL3 FM synth OPL3 FM Port
32:0 SC-8820 SC-8820 Part A
32:1 SC-8820 SC-8820 Part B
32:2 SC-8820 SC-8820 MIDI
40:0 Virtual Raw MIDI 6-0 VirMIDI 6-0
41:0 Virtual Raw MIDI 6-1 VirMIDI 6-1
42:0 Virtual Raw MIDI 6-2 VirMIDI 6-2
43:0 Virtual Raw MIDI 6-3 VirMIDI 6-3
48:0 UM-2 UM-2 MIDI 1
48:1 UM-2 UM-2 MIDI 2

57:2 Emu10k1 WaveTable Emu10k1 Port 2
57:3 Emu10k1 WaveTable Emu10k1 Port 3
60:0 Serial MIDI Serial MIDI 1
one should use "aconnect MPU-401:0 SC-8820:0" instead of
"aconnect 20:0 32:0".
the 449C fails to show up
This shouldn't be related to this change. Does it show up in
/proc/asound/cards?
