Re: Suddenly out of tune -but still problems after changing PC-1 and R93

2008-08-26 by hjulskov

Thanks Andy!

I really appreciate your help with my beloved Polysix.

Last night I tried to switch the VCO's (SSM 2056) but no change in
which voice was distorted.

Just a summary:
* All voices are equally out of tune
* 2 voices have a "distorted" effect. I will record and post a
sample... -however the frequency of the distortion changes during the
initial self-tuning procedure.
* All controlls/keys works perfectly
* My tests are performed in manual mode with cutoff=10 and resonance=0

Cheers,
Peter
