I couldn't find this anywhere, and while making signal chains, I ran into a few bumps, not knowing which FX were mono and which stereo, so I started a list.
Modulation: All appear to be stereo in except Analog Vibrato and Pitch Genie which seem to be mono in and Electron Dominatrix, which I think is mono in stereo out, but I'm not positive
I think it would be nice to see some of the signal flow or patching somehow. Could probably use some more splitting and mixing utilities to really take advantage of some of the dual path things that can be achieved with Tonestack. I want to figure out some foolproof way of determining the actual signal flow of the ABY unit, it doesn't do exactly what I think it does so I'm still scratching my head a bit on that one

All of the Distortion, OD, & Fuzz appears to be mono in except Clean Boost
