DJ Duo Setup Question

Hey guys,


so I am rly considering Djing with a friend of mine and by googling on the topic, I stumbled across this thread by Ean:
http://www.djtechtools.com/2012/09/0...-your-friends/

There he mentions the "Method 2: Modern 2X4", where you can play with 2 different DJ controllers on the same computer apparently.

quote; "In terms of gear, I personally have found VCI-100s or Kontrol S2s work really well for this in terms of balancing portability and feature set, with both controllers connected to a single common computer. "

I find this really interesting, but heres the question: How do I set up this whole thing?
I mean, me and my friend have different Dj controllers (S2 and Reloop Jockey 3). So can traktor (we both are used to traktor) handle both controllers if we just plug them in or what? :D

Im rly new to this topic, so Im rly thankful for every answer!! :)
