Welcome Matt!

    Great to have you here and joining in! Yes, the track count is a little much. Took a lot folders to organize the session.

    You should be able to handle the tracks pretty well without flipping the phase. Certainly if you're dealing with mids where the phase is less of an factor than in the lows. I suggest playing with different Q settings to effect the slope of the high/low passes to tame what frequencies you can. Everything fell together pretty well, about from maybe the bass - which was more stubborn.

    But we've all faced the same issues. The guitars took a little work to settle down and sit well in the mix. No one expects a perfect mix or anything like. We're all here to test ourselves and learn. I'd work within the limitations of the rules and see what you come up with. And have fun with it.
