Reply to QUESTION...1 VCI-100 but 2 vers. of Traktor

Ok. I have a dilemma. I have a VCI-100 w/1.3 firmware update, and the original overlay from djtt. in black (I was strictly using Traktor 3.)

I am now considering either Traktor Pro or Traktor Scratch Pro. Does this mean that I need a NEW overlay (and obviously download the new midi mappings) for my vci-100?

What if I want/need to use both programs? In the words of South Park, what would Brian Boitano do? a blank one???

I can't afford another vci....no way. Do I really need to choose between version 3 and Pro??
