Thanks for the advice so far. Ended up buying the synth. The seller was a really nice guy, very helpful. The out of tune issue seems to be with key tracking. He told me of a tech around here that has worked on a few Polysix issues before. I'd love Kiwitechnics editor, I have a JX-8P and am looking to get a Six-Trak as well. Awesome that he is your repair man jizmatron!
