Some buttons dont light up

Not sure. I don't download mappings for that reason. If anything goes wrong i would not know how to go back to regular settings. I have traktor s2 not the s4 though.

im a bit confused. You do realise that if you use the DJTT mapping then you lose the use of the loop display so it won't show any reading.
