Hello,
Have an extended period of putting this off and trying not to think about it I'm back at working on my poly. I took it apart again and examined everything and nothing is visibly astray.
Unfortunately It is a bit beyond my knowledge to electronically test the paths like you mentioned. I just don't have any idea what to do really.
I have a multimeter and use it regularly to test voltages and diodes but don't know what to do in this context.

With CN3 pulled the programming buttons do not function and do not play notes and the said keys work. With CN5 pulled (and CN3 set) the keys do not function and the programming buttons work but also produce notes. Watching the midi signals received when the functioning keys are pressed send two different notes and once. The programming buttons send only one note. Keys below the working keys transmit no midi on/off data.
