I have 3 output channels in my current configuration. I typically just use the Main outs (ch. 1 & 2) as my mix bus as the channel I bounce my mixes down on; but the other 2 channels I don't understand their application.
Just like my mix bus I can add chain bus FX, Group settings and also have the ability to bounce them as well. but there are no sends or outputs available on these tracks. When I first began using Logic I noted them but since I only required 1 mix channel to bounce my mixes I more or less just disregarded them but since I've become a bit more familiar and comfortable using the DAW I figured now would be a good time to find out what their purpose is and how I might extend the capabilities of my mixes with them.
Is there a way to add the output of these channels to blend into my main mix and bounce it down? If so, how would I do that since each of them have their own individual bounce option and if not, what's the purpose or use case for bouncing them at all?
One other question is that I do my mix down and main volume fades on my Master Chain bus so what's the purpose of the "Master" channel which has no option but to control the volume? Could it be I'm not properly using Logic for my mixdowns in the way it was intended???
