Mapping Numark DJ2GO as Native Instruments Kontrol F1 for Traktor S4
Is it possible to map remix decks to Numark DJ2GO? I don’t have Kontrol F1 and I want to map DJ2GO on my Traktor S4. There are 8+8 buttons on DJ2GO, so I thought maybe I can map but don’t know how. Thank you 
That’s totally possible Flatten.
First thing you want to to is to add new Generic MIDI Device to your already existing S4 mapping.
And from there it is only adding remix deck related commands and using midi learn to assign them to your controller. I suggest watching this video tutorial made by Ean.
He will teach you all the mapping basics and if you still need more help or have any specific questions please feel free to post questions here in your thread.

I dont have the controller but I downloaded it only to review all mapped commands and it looks like it packs some of remix deck controls
Thank you so much Stewe, I will check video. big thanks
