Made the hats during the intro fade in gradually and synced the sub bass in the intro with each kick to make it sound better. I also made the transition from double time to normal in the second drop more fluid by introducing half of the dubstep beat before fully reintroducing it.

This is a piece of bass I made for a remix competition a couple of months ago. Enjoy! :D
