question
So how does it work if U show up to a club with ur traktor scratch set up. and they already have serato runnin into there system?? And everybody else is using serato?
screwed? Or what
Laugh at them, then plug your rig into the mixer 
is there a way to daisy chain serato and traktor?
Like using the Thru outputs or something?
Most sound guys at the club are not going to like you disconnecting anything or hooking anything up. Just download serato and start using it. Not every club is going to be traktor scratch ready. If you a Guest DJ, respect the system. If you a headliner, its a different story. Its better to know how to use different DVS’s and CDs cuz you never know.
This is what I have installed and ready to go on my Mac’s: Traktor 3.4/Traktor Scratch/Serato and CDs or Vinyl (if I have to)
I wish Serato would allow midi mapping without having the box connected
