It fades in through an LP, but how can you get those grinding highs? Plus it evolves, so I'm expecting there's some automation to do. Also, when the bass is LP'd, it sort of "moves" as if it's distorted, but listening through the whole thing, it doesn't change even when the LP is off. It can't be intended distortion, meaning he didn't slap an distortion effect on it. I'm guessing it's more of a certain wave-table thing.
Any tips/suggestions?
