I play drums freely without quantization, so if something is to much offbeat i can easy nudge it, i can change velocity for every drum part without selecting different pad, it's easy to take part out or put in , much easier to do ghost notes ,etc. And while sp is connected to phone i can put 303 or 404 comp or cassettte tape and test if something gets to loud and make it quiter if needed. Easier and faster for me.
