A.Yes, you can. Record the output of the UA-101's direct monitor mixer via USB.
Note:
The UA-101's direct monitor mixer mixes the inputs from the UA-101's input jacks and the playback coming out of the computer via USB.
The mixed output is sent to the headphones and monitor output jacks, and can also be assigned to 1-8 output jacks and the digital output connector. It can also be recorded via USB on your computer.
