David R has it right.... if noise works and square/ saw don't, it is most likely between the oscillator chip and the waveshaper.... If noise also doesnt work it is in the filter stage or the VCF amp ...

Hi, group!
My otherwise awesome-looking/working has lost one of its 8-voice polyphony on the upper row. The only remaining thing is the sub oscillator (sine wave). When layering it with the lower layer this is barely noticeable, but Hell, I want it fixed. What could it be? Is it an easy fix? Anybody wan to offer your expertise? I love this instrument so much that I would not mind a cross-country drive to have it fixed!
Thanks!
JD
