Hi, Im having a problem loading a full kit on my Maschine Mikro MK3. I had it all set up before and recorded a few loops with a drum kit called "take it back kit" I changed the kit and tried to change it back, and now all of my midi notes in the piano roll have gone black instead of orange and only 2 pads are lit up. when I hit any other pads, there's no sound. how can I get the kit fully loaded back up on all pads so I can hear my loops?
