What I mean is a small but complete self-contained modular mono synth with multiple analog oscillators and MIDI, so that it could be used independently, but also in tandem with the Pro 2 controlling the pitch, and nothing more. I have no idea if DSI intends to go this far, but it would make a fabulous combination. That way, we could add as many oscillators as we wanted.
Paul, I'm perusing your Pro 2 demos again. They're perhaps the most helpful I've found. I'm considering whether it might be the right place at least to start building. My search led more or less to a dead end, so here I am again!
