I had my first go at 3 deck mixing on the weekend and i must say... HOW MUCH FRICKIN BETTER IS IT??? I actually found a new love for mixing n felt like a kid in a sweet shop as i was rippin vinyl out my box n doin mixes every 40 secs or whatever and using the filters on the djm900. It was good man. So yeah, gonna grab me a 3rd deck now n get stuck into it. If u aint already tried it, try it!!!
