The the treadle on the WH-4, idk if its just mine or if it's universal, but when shifting pitches, about 75% of the way pushed down and nothing is shifted, it does the entire shift in the last 25% of room it has left. Any way to fix this? Surely theres something wrong with it otherwise that a hell of a lot of wasted and worthless room. It's near impossible to shift it up steadily over time, it's virtually instant. I tried calibrating it, and even though it is aware of it shifting during the first 75%, the note doesn't do anything.
