I have the impression, that you should move the complete documents folder to your data disc. That can be done easily, see e.g.:

The faders have a resolution of 10bits = 1024 steps, the encoder just send relativ signals (I can't remember, maybe only +1 and -1). In the action mode a single step can trigger an action multiple times, that's the speed parameter for the action mode. But it's not possible to ignore some signals, but this is what you would need.
