This above-referenced package plays perfectly within BIAB; however, what I want to do is mute the guitar and just have the bass/drums/organ playing in the background.

When I mute the guitar and audio in the Mixer, I have just the drums and bass but not the organ. I know it can be done, because I've inadvertently done it, and I wasn't paying attention to how I did it.

And then, if I can do that, do I just hit Record to record the session? Where is the recording stored?
