Tried my new Perform-VK live this weekend, and noticed that it on several occasions stopped following incoming MIDI. It kinda just stuck to a random key. Could this be due to the room sense mic, which I guess is always on (for beaming)? Or does it come in too much "crap" through my singing mic that it confuses the VK? Or is it something else? I've had this issue with my VoiceLive Rack as well. Thanks in advance!
