Midi value  
0=on  
1, 7-127=green  
2=green blinking  
3=red  
4=red blinking  
5=amber  
6=amber blinking

To change the way the LED’s on the knobs act.

1=Single,  
2=Volume Style,  
3=Pan Style,  
4-127=Single

@photojojo i really appreciate the response but could you please clarify where i put these values and how?? i see that in the output i can mess with modifier, value, controller range (which is currently off), and midi range.

thanks again!

sounds like u need to play with the controller range as well as the midi range. i.e: what values in traktor (controller range) cause what midi to get sent out to change colours (midi range)

great! okay i have 8 cue points assigned to three decks…  
before i made the red and amber colors show the cue points would light if there was a cue assigned to it and now the just light regardless…  
for midi range i have 3-3 red, 5-5 for amber, and 1-127 for green…  
for controller range i have -1-5 on all cause i have no idea what that is…  
also do i need to do anything with invert or blend??

thanks!
