what i like to do is in a bar i split it in half so ive got 2 lots of 8 and i have the same sequence playing in both of these so it repeats itself after half a bar if that makes anysense, this is good for a hi energy feel but with a bit of funk still, if you want a real hard driving sound try one with just 2 notes repeating, for a funkier sound write a sequence that lasts the full bar instead of doing what i said about splitting the bar in half.
