Billy,
I have a KN 7000 problem with the Concert Grand Piano at times. It jumps off key while playing. If I change styles or initial it goes back to normal.

I think it is related to certain styles. When it gets to bad I will try the upgrade and see if it corrects it.
Have you installed all of the upgrades for your instument?
