**Add to 4Trak mapping. Help!**

Hi,

I have a Numark 4Trak running on Traktor pro 2.5. There are assignable buttons and knobs on the 4Trak that I would like some help in mapping to them.

I currently have the original mapping that came with the deck and would like to assign a loop function to the assignable knobs that are below the Key change knobs.

I’d like to turn the knob to select a loop length and push the knob in to activate the loop (much like on an S4).

Can someone help me add this function to my mapping?

Thanks

Mark

For loop lenght:

Add in \> Deck Common \> Loop \> Loop Size Selector \> enable learn \> twist knob \> disable learn  
-type of controller - encoder  
-interaction mode - relative

- adjust rotary sensitivity to your likings

For loop set:

Add in \> Deck Common \> Loop \> Loop set \> repeat learn process  
-type of controller - button  
-interaction mode - toggle
