Problem: PX-560 | CC doesn't provide smooth volume control when pedal is assigned to CC11:Expression   I bought the M-Audio EX-P expression pedal. Calibrated and assigned it to CC 11 controller so I could control volume with my foot. I returned it back because it seemed to be causing a very noticeable volume jump just as the layer fades in. I was expecting the expression pedal to increase the volume smoothly, just like when you use the keyboard's master volume knob, but that's not what
