Reply to Setup my Kontrol S4 with CDJ:s?

Hey guys!

Me and a friend wan't to setup our stations together. My S4 and his CDJ:s. How can we do that, so that we get it as optimized as possible? I do have the Traktor Scratch Pro 2 Upgrade kit, but where should I install it? And does anybody know how many computers I can install my Traktor Pro 2 on?

Please help me, I'm a beginner.
