Discussion about the Korg PolySix synthesizer

Hi all,

I have a polysix here that won't tune up, it drifts as though the lfo is permanately stuck on or slightly bleeding through?

Also cannot write new patches properly, at first it would not write new patches at all, found a bad ic31 74ls08, swapped that and now it saves but not what it should. for instance it seems to save almost random data or missing parameters like the lfo or res, it saves different each time.

any tips would be much apreciated.

Luke

Ok looking through the archives i can see some suggestions re: the lfo
problem.

Hi Luke,

Lots have been talked about these subjects over the years so please do trawl
through the archives! If you are having problems with tuning then you need
to look at the opto-coupler on the KLM-366. This has been mentioned a lot
plus some nice off the shelf alternatives you ca try. If your board has had
a battery leak in the past, do check to make sure all the tracks have
continuity. If so then please check IC32 which a 1024x4 SRAM.

Cheers,
Andy
