It’s the dspMixFx; it has no routing possibilities, unless you are on cubase where you can adjust your sends to the stereo out. I have the UR44C while I like the 0 latency for the headphones and the portability, I wish I had more control over the mixes and the back end. I just switched form a 10 year old sound card, an EMU 1616, where you could send what ever you wanted to wherever you needed, and choose which asio chanel the daw would run on.
