Strange. Is the snd-seq-midi module loaded?

[root_AT_Kesh linux]# lsmod
Module Size Used by
snd_virmidi 3968 0
snd_seq_virmidi 8672 1 snd_virmidi
snd_seq_midi_event 8896 1 snd_seq_virmidi
snd_seq 71480 2 snd_seq_virmidi,snd_seq_midi_event
evdev 11680 2
snd_usb_audio 81632 0
snd_rawmidi 30592 2 snd_seq_virmidi,snd_usb_audio
snd_seq_device 10184 2 snd_seq,snd_rawmidi

Do the UM-2's ports appear in /proc/asound/UM2/midi0?
[root_AT_Kesh linux]# cat /proc/asound/UM2/midi0
UM-2

Output 0
  Tx bytes : 0
Output 1
  Tx bytes : 0
Input 0
  Rx bytes : 0
Input 1
  Rx bytes : 0

In /proc/asound/seq/clients?
[root_AT_Kesh linux]# cat /proc/asound/seq/clients
Client info
  cur clients : 5
  peak clients : 5
  max clients : 192

Client 0 : "System" [Kernel]
  Port 0 : "Timer" (Rwe-)
  Port 1 : "Announce" (R-e-)
Client 80 : "Virtual Raw MIDI 2-0" [Kernel]
  Port 0 : "VirMIDI 2-0" (RWeX)
Client 81 : "Virtual Raw MIDI 2-1" [Kernel]
  Port 0 : "VirMIDI 2-1" (RWeX)
Client 82 : "Virtual Raw MIDI 2-2" [Kernel]
  Port 0 : "VirMIDI 2-2" (RWeX)
Client 83 : "Virtual Raw MIDI 2-3" [Kernel]
  Port 0 : "VirMIDI 2-3" (RWeX)

In the output of "aplaymidi -l"?

[root_AT_Kesh linux]# aplaymidi -l
 Port Client name Port name
 80:0 Virtual Raw MIDI 2-0 VirMIDI 2-0
 81:0 Virtual Raw MIDI 2-1 VirMIDI 2-1
 82:0 Virtual Raw MIDI 2-2 VirMIDI 2-2
 83:0 Virtual Raw MIDI 2-3 VirMIDI 2-3

Does this answer any questions ?

Thanks,
Elias
