Discussion about the Korg PolySix synthesizer

So after I fixed some grounding issue yesterday, it seems that my Polysix doesn't recall the patches: they're all initialised to random, not-too-usable sounds.

Where should I look at testing on the boards (KLM-367 at least, correct?). Any particular chips + traces?

Before my fixes yesterday, I did manage to briefly recall my own patches internally, so I know the battery is good, the memory should be good and I'd tend to think about some bad trace somewhere instead.

Thoughts on how to narrow it down?
