The Behringer arrived today and it seems to be working! I had a slight complication when I first connected it because my DAW recognised one "USB Codec" device, but it was output only. No inputs at all. I went into my Mac's Audio/MIDI settings and there were two separate hardware devices detected, one for input and one for output. I created an aggregate device for both, restarted the DAW, selected the aggregate device as its sound card, and it works. This is slightly annoying as it adds about 6ms of latency to the input (for a total of 7ms). Any advice on that would be appreciated, if there is a way around it. I'm assuming this latency is because the audio is having to be routed through the software aggregate device which adds processing time..
