I found some little preset Riff music sample under simsynth called "radiosynth" and decided to play around with it to see if i could make something cool..

This is what I came up with x3

This is set at 114Bpm
and took me about 20mins to throw together =P

the base riff is the few seconds in the beginning.. everything else I added and composed by ear..

ok ok so maybe the drumloop is also a preset loop Dx
