- 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
-
- bits
- nn 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
