Wouldn’t it be awesome for the Op-1 to be usable as a vocoder?
Did anyone try?

I was wondering the same thing recently and came across this thread.
Sounds like it’s sort of possible.

This is essentially doing Amplitude Modulation via an envelope follower. It will not sound as clean as a ‘proper’ vocoder, but will have a nice lo-fi AM Radio sound rather than adding overtones to a synthesized carrier.

I completely agree but for now… one thing I did find interesting was when I paired the OP1 with an old BOSS SE-70. That thing enhanced the OP-1 massively, still kept a small footprint, and has a great vocoder!
