I’ve been using Steinberg UR44 for a year now. Never had any problems with it, as I only used USB Port, Main Output and Mic. Line. This week I decided to connect my Traktor MkII by Native Instruments via the two TRS line inputs. My controller shows that the sound is working, but UR44 doesn’t receive it. I think that there’s a problem with the input itself, but decided to ask you guys, just in case. Maybe I’m doing something wrong.
