   4  WaveArtist mixer and volume levels can be accessed via these commands:
   5
   6   nn30  read registers nn, where nn = 00 - 09 for mixer settings
   7                                               0a - 13 for channel volumes
   8   mm31  write the volume setting in pairs, where mm = (nn - 10) / 2
   9   rr32  write the mixer settings in pairs, where rr = nn/2
  10   xx33  reset all settings to default
  11   0y34  select mono source, y=0 = left, y=1 = right
