I appreciate all the suggestions.
I'm not against using Audacity, as I am broke and prefer a free program at this time. The thing is, I haven't yet figured out how to do it.
Editing a stereo (2-track) recording is easy. I do what I need to and end up with a 2-track stereo recording, just as I started. Now that I'm doing 3 and 4 tracks, I need to "blend" the tracks. In the case where I record 3 tracks, the third is a mic used for audience/ambiance and needs to be added to both the right an left tracks from the soundboard. In the case of the 4 tracks, they are mostly 2 from the board and 2 mics on stage...and I need to mix the rights and the lefts, etc. I'm new to recording more than 2 channels, which is why I'm asking for help.
