Midi in Traktor is not as tight as HID. However certainly usable, if you adjust the rotary mapping settings. (Ok Steve Canueto the scratch tutor may disagree with me on this one. ) 😉
First you must be ok with mapping in Traktor.
Second take a backup of your settings.
For each of the scratch mappings there are Rotary sensitivity and Rotary acceleration.
The sensitivity is the main one you need. Play with the lower end of the setting and keep seeing what the response is like, sometimes even a 1% change makes a big difference. Keep moving the jog until you get the sort of response you want. It is never perfect, but worth a go if you already have a controller.
