Its samples loaded to the buttons of the pad. Hit them on time.. as u feel.. now this... then that.. First selection of the patterns, loops and scratches are important.. for this definately u need to have sense and good taste and choice... then practice hitting them on time.. mix and match .. but the finger drumming was good.. Deffinately the guy has good drumming sense and skill.. He didnt just play the samples... but also played.. good job
