Live from Toronto Mixette - Knxwledge

I have to admit that I'm fairly ignorant to a lot of the dub step stuff. I know about Flying Lotus, GLK, Ras G, and the rest, but I'm certainly no expert. With that said, can anybody tell me whether a mix like this one is done with turntables? Or, is this mix the product of some super scientifical mastery of a SP-303/404? Just curious. Either way, the mix is money.
