Yes, I've read and followed the instructions on how to use the function button, etc. Nothing I do in the temperament field changes the pitch one cent - I've checked it with a tuner, and it's always the same. The factory default seems WAY over-tempered... the lower register is too sharp and the upper too flat. Am I missing something here? Please help. Thanks.
I have the same problem with my PX-780M. I've followed the directions to the letter and cannot change the temperament one cent. If this is the factory default, it's really severe... the upper register is way flat and the lower is way sharp.
