Discussion about the Korg PolySix synthesizer

Well, I fixed my dead keys - 
turned out the yellow 16-way cable and connector were fine, 
but there was a dry joint on the D0 line, on the keyboard PCB, between the connector and the diode.
(Actually, that one isn’t even a diode, it’s just a piece of wire!) 
I guess all those thumping bass lines over the years must’ve weakened the joint.

Thanks for the help, everyone.
