Discussion about the Korg PolySix synthesizer

The issue is that the main CPU board does have a fault. I'm trying to diagnose where this fault is.
It's not a calibration issue.

I suspect that one of the data lines is being pulled high or low. I've got my scope back from a friend, so this will help diagnosing what is at fault.
I'll report back with any updates.
Kind regards.
