I got a used Kontrol 49. By toying with live settings, everything is working, except that the drum pads don't transit velocity information.
When I navigate to the pads settings, it says velos and not "constant". Still, when I click a drum rack, the pads will automatically map to the 16 displayed samples, but only with maximum velocity.
When I first got the controller it had bizarro problems, but the pads were velocity sensitive. I reset it and now it works but not the velocity.
