Hello,
I'm working on a Polysix repair project. I've replaced the unit with a new KLM-367 clone CPU board and it sprung the whole unit back to life except there are about 7 dead keys throughout the keybed. Oddly enough, those same notes are playing while the arp is engaged. Has anyone come across this? Sounds like an issue around the key assigner board. Also the while Chord Memory is engaged I get a hanging note as I depress any key.
Thanks.
