Hi,
I tried to join the Technics Canada Forum site for over many months, but it looks this one remains closed forever.
As some of you know I owned a KN2k, KN3k and a KN5k and was a frequent visitor of the Technics forum. The X1-bugs were solved in the 2nd OS and the latest version is 3.1 (the 4th upgrade)
Larry : your problem looks to be a 'loop' in the MIDI circuit. If your computer is connected, a sequencer is running and the midi-thru is ON, this might cause your problem.

I still don't like Technics' attitude (anymore) ;-)
