See page 159 about keyboard scaling which could be associated with your problem.

'Both pitch bend wheel and modulation do not work at all' Paradise says - that tells me that that is the reason why the left hand is out of key with the right hand...the machine has been dropped and what those wheels affect are broken...replacements are available.

Oh yeah, that would cause serious tuning problems.

Paradise19, are you in the USA?

Set the split point to the far left hand "C" and see if all the keys are in tune now. (you will not have APC unless you are in the pianist mode for this test)

My guess is that the pitch bend wheel pot or circuitry is bad which may or may not have been caused by a shock such as dropping. There would be obvious damage to the case if it had been hit that hard.

There is excellent service available in Florida . . .

Paradise, the symptom acts like the pitch bend is locked to one extreme so that the right hand voices are moved up or down from the tuning center. Disconnecting the pitch bend may not work. The connection needs to be at the center point of the pitch bend variable resistance.

If the above assumption is correct, and if you move the split point all the way to the bottom C, and if you keep the APC setting at basic or fingered, the keys should be in tune across the board but with no rhythm. Selecting the pianist mode would result in the same symptom you are now seeing if APC is on.
