I'm still confused. I'm not talking about changing presets at all. I'm talking about 1 preset, not changing to another one. The HD500X allowed you to set the minimum for the expression pedal, say 30%. Then, whenever you brought the expression pedal all the way to the back, it would hit 30% which you've set, not 0%. The Helix doesn't seem to let you do this, at all. Pretty disappointing!
