One thing I NEVER do is to use the EXPORT feature.
I rather use the "BOUNCE TO TRACK" function, from this, I bounce a Entire mix,
so there I can compare my actual tracks along with my bounced mix.
Make sure to route that track directly to your hardware outs (bypassing the mixer),
then you could even try phase flipping the track to cancel with your mix.
Comparing the 2 tracks cannot get easier than this,
So when I'm done comparing, I just drag+drop the mix track into my file explorer and rename.
Voila. I hope this helps !
Cheers !
