Hahaa dubble wubble. I experiment with it a lot. Actually right this second I'm writing a dubstepish song that is doing it.
Wav 1: bass wub and sampled snare (saw)
Wav 2: wav kick and bass wub with an octave gate thing table (square)
Noi 1: fast hihat perc
Noi 2: openhat perc and snare
Pu does whatever it feels like. Double lead sometimes. Lots of crazy stuff cause it's dubby
