I've never really seen anyone fully rock it on Ableton, and I've seen loads of folk use it. Sets done on it always seem (at the best) un-dynamic, flat and predictable imo.

There's definitely a lot more could be done with it to make an interesting set. Though maybe it just comes down to the fact that I don't like a lot of middle of the road techno so therefore don't enjoy it being repeated ad nauseum ?
