2: Part a and b are synth, Feed a and b to the ring modulator, mix modulator output with a
3: Part a is PCM, b is Synth, Simply Mix A+B
4: Part a is PCM, b is Synth, Feed a and b to mod, mix a w/mod out
5: Part a is Synth b is PCM, Feed a and b to mod, mix a w/mod out
6: Part a and b are PCM, Simply Mix A+B
7: Part a and b are PCM, Feed a and b to mod, mix a w/mod out
8: Part a and b are synth, Output A to Left, B to Right
9: Part a and b are PCM, Output A to left, B to Riight
10 Part a and b are synth, feed a and b to mod
11: Part a is PCM, b is synth, feed a and b to mod
12: part a is syn, b is PCM, feed a and b to mod
13: Part a and b are PCM, feed a and b to mod
