To Mac: Yes, I read the manual, all of it... over and over, but it's not sinking in. Somewhat complicated to my little brain. My RealTrack tracks don't seem to coincide with their Mix tracks, probably because of the way BIAB uses the first 9 tracks, but at this point I'm not sure what I don't even know. What I do know, is when I get this figured out, it is going to be something because the sound that I'm getting with this product is amazing! Everything appears to be working, I just can't hear it until after the fact, thereby contributing to the recorded vocals to be flat.
