I agree with this assessment. This sounds like the classic keypoly
problem, which I just fixed on my own synth this weekend. You need to
solder twelve wires across the back of the ribbon cable, which reside
beneath the middle keys. Now it works great.

My next problem\ufffd how to get this heatsink to not be so hot? Wow does
it get warm.
