I have a QS + piano that while in the middle of playing from the keyboard OR while playing a
midi file, goes out of tune. The notes actually sound like somebody is playing with the pitch wheel
while I am playing. If I restart the keyboard it may or may not be Ok after that. Also, if it is doing
Ok and I adjust the pitch wheel at all, it will go harwire and every note played after that will
sound out of tune. Wondering if I need to take it in for repairs or what.....
