Hey guys, I recently bought the AKAI Professional MPK Mini MK3 but I got some issues trying to figure something out and was wondering if anyone could help me out. How do I change the note of which the drum plays when I hit the pad. The notes change as I go from one pad to another but I want to pick a specific note and wasn't too sure how to do that.

DAW: FL Studio 20
