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
