that’s cool

I can think of a ton of possibilities with the MOOG MP-201

since you can send an LFO signal, you could do auto wah, tremolo, and vibrato automatically with that. . .
and it also has a sample + hold feature, which could yield some other very interesting effects with the HOG.

Plus what’s really cool is you can adjust the sweep of the expression pedal so that it will sweep through steps
so you could tune each step to intervals- play a note, push the treadle down, and sweep through an arpeggio.

And the other awesome advantage is that you can hook up 3 other pedals that use CV to it (you can do 4 CV or 3 CV and 1 midi I believe) and you can program what it does to each pedal specifically. . .

So you could have a sample and hold on your Polyphase that increases in intensity when you toe down while the HOG steps through different pitch shifts.
