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 | |
