I think I’m having the same issue as everyone else. My kick is playing fine but the trigs I laid down on the snare and claps aren’t registering. Checked to make sure mutes weren’t on. Removed the trigs and laid them down again. Nothing. The corresponding pads are making sounds fine when I tap them, no issue there – just nothing playing in the sequencer. Other tracks seem to trigger fine, so far it’s just the two not playing. I’m using samples, machines are disabled (kick is a combo sample/machine and playing just fine; samples loaded on other tracks working fine).

Man, this is extremely disconcerting! I just switched over to the MK2 (Black) and this is one of the first things I discover. Latest firmware loaded. WTF?? I never experienced anything like this on my MK1 and now I’m really missing it…
