Just got it sorted! My volume was low as heck. I turned off the piano and did a factory reboot. (Not necessary thou but i just bought this used today) Basically held the far right key down and then turned it back on.
THEN.....hit the function button then Use the white "arrows up" button under the big black knob. Push the arrows up button until the screen reads TouchSns. (Prob 6 pushes) When you see that, use the big black knob and circle it to the right until you get to number 4 on the screen which removes the soft touch. NOW your keys should be loud as heck! You're welcome!!
