Hi guys,
Recently bought a K3 to use for traktor effects only. After hours of reading and watching videos as was my 1st time mapping I have successfully achieved what I want each button to do.
My next objective is to map the LEDs…
I figured it out, and was successful in making the button turn green when said effect is on.
This seems to work fine when I do deck a&b but unsuccessful on c&d?? When I press “invert” the button lights up green so it is working one way but not another 
I have followed the correct notes and numbers
This has baffled me to be honest.
Ive stuck with just deck a&b for now but would like to carry on my mapping to all 4 channels.
Any help would be appreciated
