I am a beginner so please pardon my ignorance. I have an using Audient evo 4. I installed Studio One 5 Prime. In my project, I assign Mic 1 to track 1, Mic 2 to Track 2 and I want to assign Loop-back 1 (L) and Loop-back 2 (R) to Track 3. That way I can record voices from 2 microphones and computer audio together and create a single audio file. When I make changes in Audio I/O Setup, I am unable to save the Loop-back assignments? What am I doing wrong? Please help.
