Hi
Servicing a Polysix for a client, and have come up against a weird issue, which I can't fathom. Hoping someone out there has had a similar issue, and may be able to help...
One voice has a faulty filter section in that the resonance can be adjusted as per the line up procedure, but then if you lower the cut off, the resonance decreases.
I have ruled out the problem being the SSM2044, all signals coming into the chip (ie. cut off/resonance control etc.) look correct, and are comparable, and I'm pretty sure it's not the filter caps as they're not electrolytics or Tantalums.
Also the connections between the caps and the filter chip are all OK.
If anyone has any ideas, please get it touch. It's beginning to drive me mad.
