I have never really used sub-groups in my mixing. Part of that is I very rarely use more than 10 or 12 tracks. But, for instance, say I wanted to put all my guitars in a submix group. I would bus them all to say, 3-4, and then apply comp and eq to the group. But at that point, I'm hearing the auxilary track, and the real tracks, right? I can't mute the real tracks and only hear the submixed group, can I? do you guys normally print the submix to audio and then apply comp/eq, etc. Thanks. It's just a technique I don't use day to day, and would like to experiment. I know there's no right answer, but I'd love some ideas to try out. I usually record songwriting demos at home with drum loops, a little midi, my stuff is mainly guitar based. I have some stuff posted here, if you're interested. thanks!! bp
