Reply to VSI-100 mapping to controll pan

Hey everyone ive just done my first 2 evening s in a club and loving the vci-100

I was wondering if anyone had a step by step guide to change the mapping so the Gain Knobs changed the Pan instead
as i always use auto Gain it seems like a waste of knobs on the vci

Ive never changed any of the mapping so hope someone could help
or maybe someone has done it already

Also i couldnt use traktor in full screen mode without it freezing every now and again that maybe my laptop though it is getting on abit
