Read about Chris Liebing's complicated DJ setup
/From an interview conducted by Lessthan3:
"I work with two computers that are linked via ethernet cable. One runs Traktor, which is the master clock, and one runs Ableton. I'm using an Allen & Heath Xone:92 with sends and returns, so I have four channels coming out of Traktor. I have Maschine running as a plugin in Ableton, and I control that with another controller. And I have the internal effects of Ableton running, as well as external effects via Traktor. It's all automatically synced, and some people try to give me sh*t about it, but it has to be for the way I play."
Who cares about beat matching when DJs have this at their disposal.
