Reason for posting - idle curiosity. I'm not going to unnecessarily
delve
into the keyboard section to find out.
I was surprised to see just an 8 way ribbon cable going to an 88 key, 7+
octave keyboard.
I assume there is active multiplexing hidden in there , but would there
be
"touchy-feely" action monitoring as well.?

Yes.

Play a note too pianisimo and it fails to register at all, taking say 3
