Aye, it's triggered to all hell so he barely has to hit it. He's sloppy as hell live, so it'd probably be a real struggle if he had to bash it with any power.
Strictly speaking blasts are unison or etxremely fast alternating kick and snare grooves. So at 180 odd bpm you'd be playing a snare on every semiquaver. I'd think it'd sound quite bizarre in stuff like Dragonforce. It's usually a black/death metal and grindcore thing, though it comes from crust punk, to start with really.
