It seems the information available on this is scant, but here's my guess:

The following are textual descriptions of what I seem to be seeing in the diagrams:

1: Part a and b are synth, Simply Mix A+B
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

Yeah, the 13 mixing styles are emulated completely and from what I believe correctly. See lines 429-450 of CPartialMT32.cpp. I believe it may be decieving as I only test for 4 cases, but that's because of the 13, there are only 4 true variations. The only other variation of those types are between waveform and PCM sources. At this point in my emulation however, my software is agnostic as to the original source, though it does use this information earlier on to decide whether to play a waveform or PCM sample.
