Archive of the former Yahoo!Groups mailing list: Discussion about the Korg PolySix synthesizer

I bought a Poly six on E-bay. Of course it has some problems. I did
the "OldCrow" battery mod and trace repair to resolve any problems
associated with battery leakage.

But Now I still have some issues:

There is a problem when the resonance is up high and the eg reduced,
five of the six voices are quiet and the sixth is very loud. Also some
distortion is heard on some voices but not others when the resonance
is cranked.

This weekend I tuned all the voices to each other. The high range now
plays in tune relative to itself. The low range has a progressive
drop off in pitch, the farther down the board you go the more it goes
flat.

Also when holding a key down the tone will go into oscillation
intermittently, and especially before the unit warms up. A patch with
no modulation will suddenly start warbling if you hold a key for a few
seconds.

Anybody with any ideas?
