universal dj traktor mapping

hi, i have a universal dj controller, and im using traktor 3.20 

i downloaded the dj_uni_tp2_v271 file and most of the controller works, except the gain knob and the "loop" buttons... how can i solve this? is there a tsi file somewhere with the updated mapping?

thanks a lot in advance

Hello,

Sorry but during the confinement I have no access to a Universal DJ. 

No worries thanks anyway!

If someone else knows how to do it? 
Thanks so much 
Joan
