Right, so I just got me a second hand PadKontrol and it has a drum roll function, sort of like the note repeat on the MPC but you use a X-Y pad to control the roll. Problem is that when I do a roll, it doesn't come out smooth and linear but interupted and seems to have a rythm of its own. How do I set it do nice smooth rolls instead of interupted ones? I looked in the manual but I still don't know. Had the same problem with my MPD 18 too.
