I tried panning the distorting voice card and cleaning the pots- it didn't help. I do only
hear it when I have OSC 1 engaged - with just OSC 2 I don't hear the distortion. The weird
thing is that I tried replacing the Curtis 3340 for OSC 1 and I get the same distortion, so I
don't think it is the chip. Any other thoughts
