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

I recently had my Polysix KLM-367 board serviced through Old Crow (replacement, rather)
and just got it back a few days ago. Unfortunately I needed to re-calibrate the oscillators
and tune them since it sat for so long not being used. But the tuning is still off - not really
a seperate oscillator problem so much as I can't get it to the right pitch using the tune
knob. Even at the max to the right (sharp) I cannot get the unit to hit a perfect a-440.
And just to clear up the dummy-factor, I even made sure that the tune knob was set at
dead-center when I began the oscillator tuning, so i would have flexibility in both
directions if the tuning shifted. I am about to re-do the process but I am curious if
anyone else has suggestions as to why this may happen even though I kept the pot at the
center? Any help is appreciated, thanks.
