I don't consider the apc control to be a problem, more of a matter of preference. If the apc main control is moved, simply move it back to maximum while the next style is loading. Set your apc levels for each particular pattern/style with the screen control, and save it to sd/disk so it will always be where you want it and leave secondary volume to the main slide control. Sort of a fine-tuning adjustment. I seldom adjust the apc, since there are other ways to control the volume of individual voices. But, since I do like to feel the music as well as hear it, I generally keep the volume high. Still, if you favor certain styles when you play, simply save your favorite settings in memory banks. Instant recall.
