Hi Larry.
I've had my KN7000 since late November, and (knocking on wood) had no problems with her what so ever. I have only used the instruction book following the keyboard, and the things I knew from the KN6000 - and then started playing. Today I'm doing my gigs and small shows on the 7000, showing others, what the little devil can do - so just get on with it - if you have any questions, you are also welcome to mail me directly - maybe you can get a quikker reply then.
Kind musical regards
