When playing a rhythm in left hand I still hear another sound add on at the same time when I press the key. How do I turn off second voice of left hand.
This is happened when I upgrade to the 5.1

which keyboard ?

This is for Audya 5 keyboard
More explain about the question I has. In the button when you select a split place key like C3.
1.Is the sound (any voice) can’t here from C3 point and below when I press any key bed? Because this is a split point. I can’t see any solution to turn off the sound that why when I play a rhythm I can hear it adding another sound to the rhythm when I press the key
