I've got an Ensoniq SQ2 keyboards, its sample based and has 3 "voices" per patch. Its got a few generic analog waveforms, triangles and things, and I was wondering if anyone knew whether it was possible to get the voices to modulate each other, hard sync being what I'm looking for. I've been looking through the manual and haven't been able to find anything but the thing weighs a ton and reads like a dictionary so I might have easily missed something.
