Certain keys on the Yamaha P-125a may produce a different or odd sound when pressing two keys due to the way the keyboard processes multiple key presses. The issue could be related to the "Dual" or "Split" modes, which allow different voices to be assigned to different sections of the keyboard. Additionally, the document mentions unpredictable behavior when multiple keys are pressed at the same time, possibly involving the sustain pedal. This suggests that certain key combinations and pressure levels might trigger unintended sound variations.
