Well i guess its more of experimentation in my opinion when I try and create lol. When I play to cd's I try and perfect my outside the pocket complex fills that I hear. Also when trying to come up with something new, I just substitute and switch around my kick, left and right hand around in common and favorite rolls that I use. It sounds different and fresh. Sometimes I even run into new things and I'm like wow Im gonna keep that one lol. Sometimes for the fun of it, I try and start and end my fills at times that aren't common and traditional. For example, instead of ending at the 1, i try and end up at the 2 or the 3. Or even more complex than that I try and come in on off time 8th notes. I dunno Maybe im on to somethin.....or not. lol
