S&K-Final Boss Loop (Rain Mix) What. Just, what.
Alright, first off, this is a midi, which you most likely stole from somewhere else. I'm not entirely sure about this, though, you might be the author of the midi, but the chances of that are very slim.
Also, the second part sounds like you've just played 3 versions of the track (all with different pitches) at the same time.
