 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
