**Numark Mixtrack Pro LED Mapping** Hi, I’ll get my Numark Mixtrack Pro in 2 weeks but I have a few questions; • How can I blink play/pause button while song isn’t playing ? • How can I blink a led if loop is active ? Best Regards ---

Hey Deniz, you cant use beat phase command to make LED blinking because it require deck to be playing. However you could use loop recorder position to create same effect but you’ll be giving up for loop rec functionality or to sacrifice one deck that’ll be always on play to provide state for other decks. https://www.youtube.com/embed/qcA-KMnwal0?feature=oembed&wmode=opaque ---

Can we handle blink action with some controller range min/max values?
