Reply to Traktor Hotcue States and APC40 Clip Launch Grid

Hello all,

I'm currently using a VCI-100 as my primary interface but I decided to mess around with the APC40 that I have to tinker with using the clip launch grid for Hotcue launching. However, I'm running into some confusion regarding the LED outputs and I was hoping someone could help me understand things better.

What I am ultimately hoping for is to have the APC40 clip launch rows 1-4 buttons 1-8 map to Traktor Pro decks A-D Hotcues 1-8 respectively. Now, making the actual launch trigger work is trivial however, it's a bit of a confusing bundle of buttons when none of them are lit. I figured the LEDs on the APC40 would be ideal since they have multiple colors.

Imagine the buttons....
- dimmed out when there is no mapped cue
- lit up yellow for each cue point
- lit green for each loop
- lit red for fade in/out cue points
- each of the above blinking when it's the active cue

Having access to all the hotcues for all 4 decks at once could be a lot of fun.

In Traktor Pro when you set a midi assignment for Hotcue State the controller range defaults as -1 to 5. I believe (sorta guessing) that maps to
-1 - no mapping
0 - Grid
1 - Cue Point
2 - Load
3 - Fade In
4 - Fade Out
5 - Loop

On the APC40 each clip launch has the following state numbers
0=off
1=green
2=green blink
3=red
4=red blink
5=yellow
6=yellow blink
7-127=green

Now when I load a track with regular Cue points saved as Hotcues 1-8 and I use a midi mapping for Hotcue 1 State (controller range = -1, 5 and midi-range 1,1) then the clip launch button correctly turns green when I load. Awesome! If I change the midi-range to 2,2 then it blinks green when I load the track. So on and so on.

Ok so that seems fine but the issue comes in when I "use" the hotcues. As soon as I press the button mapped to Hotcue 1 the light goes out and wont come back until I reload the track into the deck. Press it again and poof the light is gone.

It seems like something or other causes Traktor to reset the state of the LED output to off as soon as you use the cue... doesn't seem to make any sense and that's why I am stuck with it.

I've also tried mapping where the controller range was set as -1,5 and midi range 0,7. when this is the case then each hotcue type correctly gets one of the different color patterns. This still doesn't change the LED from going out after the first time you press the button.

Is there something about "Hotcue # State" that changes when you trigger it which would cause LED Output lights to cease to function when mapped accordingly?

Thanks for any tips or ideas on fixing this!
