I'm currently trying to map my APC 40 as my Traktor controller. I used to have a S4 controller with the loop rotary right and the search/seek trough track rotary based on the loop size. But I can't find the right way to map the search/seek rotary to one on my APC. I've searched on internet and found some possibilities on this forum but I couldn't get it to work. Can someone please help me?
