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
