**APC40 LED Question** When mapping the hotcue states to LEDs to reflect when a hotcue is present or empty: loop, grid, and load cues are showing the “empty” color i’ve mapped in Traktor. I’ve mapped it as such: -controller range: 0/1 -midi range: 3(red)/1(green) My understanding then (correct me if I’m wrong, please) is that Traktor uses 5 cue states: cue, empty, loop, load, grid. How can I map the LEDs to address all 5 of these so that it recognizes the loops, loads, and grids? I have a feeling it has to do with the controller range being 0-1. One other question: If I wanted to map LEDs to reflect which deck was in focus, how can I make sure that when I move a deck into focus that the other LEDs indicating deck focus turn off? ---
