(Alsa) MIDI no sound.

[Bert Haskins]

 I can't get any sound out of either Rosegarden4 or Muse.
The Midi file  loads and  runs  but  is  dead  silent.
Sound  is  (very) good  under  XMMS .
Lsmod shows all of the SND modules loaded.
Alsa-mixer doesn't show a slider for anything that I can relate to 
Midi??????
What am I missing?
Thanks,
    Bert
