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
