Taffy!
I really don't get the point of 400 bpm. Can the brain even interpret sound that fast? I know that the fastest a human can take in visualy per second is 24 frames, it wouldn't suprise me if there is a similar cap on sound. And for the most part, I can't really hear the benefit of speed core. Though the speakers I have hooked up at the moment SUCK. For some reason my good ones stopped wortking.
Despite the 400 bpm thing, I actually liked what I could hear through my muzzled speakers. The hard rhythem was really neat. It was hard to predict, and the background instruments didn't over power the rhythem at all. The synth melody was really earie and cool. Really, you did a good job here. I can't say i've heared too much like it. I wish my speakers didn't suck so much. I gave you the benefit of the doubt for clarity. I also gave you a 10 for effort seeing as how you worked at...well...400 bpm.
