Phase problems after Processing SD2 file with TComp/EXP

Hi!
I was "mastering" a Horn band album a few hours ago and then I faced this problem..
My client, the conductor, felt he conducted with a too low bpm.. yes, after almost 6 months of recording/editing/ production's day 01.

Ok, I could do the TC exp to every single track..OH My God...

Hi everyone, I want to make a stereo bus of my drums so i can compress it to hell and blend it with the original kit.

Is Phase a problem in a situation like this? :D
