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