I saw this guy Paus on a swedish program once (think it was an "amazing artist" show called coloseum or something) and I couldn't believe my own eyes. He sounded like a god damn keyboard shifting notes without distinct keychanging. But I doubt that he could do 64th notes in 300 bpm.. I mean, I've been playing on speed for a while and I can barely play 32nd notes in 130-140 bpm. It's not human, it's no need to argue about it. =)
