Reply to Filter 0% mapping for a knob

Hi,

I know I just saw some reference to this issue somewhere recently but I cant for the life of me find it. Hoping somebody can help..

I have a knob that I use for traktors internal filter. The problem is that when I put it to 12 o'clock, it sometimes stays on 2% or so (+ its hard to tell in traktor if its only slightly off center).

I was believeing that I could adjust the mapping so that the knob basically turns the little circled light (in traktor right next to the filter knob on the screen) off when I reach 0% and then turns it back on when I go +/- 1% or more.

Can anybody guide me in the right direction here?

Can I do this all via a single command for filter ON or do I need multiple commands?
