New RM 32 user. I need to record 22 channels at a live show. Not all of these inputs (bass guitar, horns) need to be in the FOH mix, but I need them on my recording. How do I set up in UC and Capture to assure good strong levels that I can go back and mix later in Studio One? Is this an aux routing issue? Forgive me if this is basic stuff, I am a newbie.
