Discussion about the Korg PolySix synthesizer

I've got a Polysix here that doesn't seem to initialize properly on cold mornings. Symptoms range from mild to bizarre. Sometimes I turn it on and the lights all come on, then it switches to just A,1,Poly like it should, but doesn't seem to have loaded all of patch A1 parameters properly. Hit the "1" button again and it's fine. Other times, none of the lights go off and hardly any knobs respond. If I leave it on for a few minutes, then turn it off and back on, it fires up properly. The Reset adjustment procedure was done after it was warmed up, as per instructions. Could it need tweaking for cold starts? How exactly does it work? With that big C21 and a zener, it looks like it just delays the initial reset until the 5v supply is up to snuff.
