Yamaha Clavinova CVP96 Plays the Wrong Notes

by Lawrence
(Independence, MO)

I am having an issue with my piano. If I play the keys individually it plays correctly with no problems. But if I attempt to play a chord or multiple keys at the same time it does not play the correct tones. For example if I play a C chord I can plan C, E, and G individually and it plays the correct notes for C, E, and G. If I play the if I play the chord (C, E, and G at the same time) it plays C, E, G, and Bb. This does this over the entire keyboard it is not centralized to 1 part.

I am baffled on what is causing this. Please let me know if you have heard of this before and what the solution could be.

I hope you can help as the issue I am having has made my piano redundant.

When you play a note/ key, a C note/ key for instance, it plays the wrong one. If I play a B or G or any other note it does the same thing. Also to add, some of the higher end keys aren't even working.

Has anyone else come across an issue like this before? Has the main controller gone or is this an easy fix? I paid a lot for this piano a few years back and I don't want to just get rid of it.
