I've created a drum mix based around the overheads mics. I'd like to produce another mix within the same project based around a couple of room mics we set so I can A/B the two mixes.
Is that possible?
You Can route your audio channels to multiple buses, so your main audio channels don't have an output, you don't do any mixing on those channels. So for example if you have 5 channels of audio, route them to buses 1 to 5, do your mix on the buses, send them directly to a sub-mix on bus 11 and from there to the master out. For your second mix route the original audio channels to buses 6 to 10, sub mix them to bus 12 then the master.
you can A/B the two mixes by switching between bus 11 and 12 with the solo button.
Alternatively you could record your mix data in the arrange. Mute the mix when you're finished and record the second take, then just mute/un-mute the data channels as you wish.
Conceptually, you could group your tracks together and then duplicate the group. Mute your first group, and make whatever changes you want on the duplicated tracks to make a new mix, and then solo/unmute the groups as a whole to A/B the two mixes.
I don't know how to do this in Logic specifically, but the basic idea is something that I imagine most DAW software such as Logic could handle.
Another way is to make folders.
From CH 13 of the manual:
Just put together some screen shots since I couldn't figure out how to carry over the formatting. Hope it helps! With Folders you can just copy the entire folder, mix differentl, mute/unmute. Easy =)
