I don't think it was serato they were making fun of. They took a stab at Elliot and his AEM-100 AI Mixer with those buttons. I think their approach is sort of "Tim and Eric"ish and not supposed have meaning, other than "If you don't use our mixer, you are a crap DJ." Hey I've had that Xone02 mixer for 3 years, so I guess I ain't no "Crap DJ", haha. I also have that AEM-100 mixer so I guess I'm neutral.
