Sort of like scaling the entire motion path of keys in = one or all directions, but tying that to a slider, so that when the = slider is at 0, there is no motion. ie it clamps all values to = 0.

There is probably an easier way to do this but I was wondering if = this it was possible like this. = Thanks,
