Worked, gave a single half second tone.

Tis loaded already:
[gene at coyote midi]$ lsmod|grep snd_seq_virmidi
snd_seq_virmidi         3864  1 snd_emux_synth

[gene at coyote midi]$ aseqdump -p "Virtual Raw MIDI":0
Invalid port Virtual Raw MIDI:0 - No such file or directory
Repeat for :1, :2, & :3

Since I got the above error(s) I looked it up and did this:
aconnect -i
client 0: 'System' [type=kernel]
    0 'Timer           '
    1 'Announce        '
client 14: 'Midi Through' [type=kernel]
    0 'Midi Through Port-0'
client 16: 'SB Audigy 2 Value [SB0400]' [type=kernel]
    0 'Audigy MPU-401 (UART)'
   32 'Audigy MPU-401 #2'

Which I think is telling me there is no thru port to the synth?

aconnect -o
client 14: 'Midi Through' [type=kernel]
    0 'Midi Through Port-0'
client 16: 'SB Audigy 2 Value [SB0400]' [type=kernel]
    0 'Audigy MPU-401 (UART)'
   32 'Audigy MPU-401 #2'
client 17: 'Emu10k1 WaveTable' [type=kernel]
    0 'Emu10k1 Port 0  '
    1 'Emu10k1 Port 1  '
    2 'Emu10k1 Port 2  '
    3 'Emu10k1 Port 3  '

So I think I need something else yet?

Thanks Clemens, between you and Paul, I may actually be learning something. 
:)

Cheers, Gene
