I wanna map my RMX and APC40 for Traktor. Can I use the same .tsi file?
I haven’t finnished planning it out yet, but I’m thinking if I want to control an LED on my APC40 by pressing a button on my RMX, the only way to do that is to use 1 .tsi right? Am I mistaken? If I use the same TSI, is there a chance i will run into signal conflicts? Can I just run them on separate MIDI channels? 
Get my drift? Thanks.
