There are few things that strike so much fear or disdain for Logic users than the word gain staging.
I am a firm believer in gain staging. I did it a lot setting up for recording live from a Mackie mixer. The band thought the proper way to control volume was to adjust the trim pots, never mind the faders on the board. I tried to do it every time, but that wasn’t always easy. It was the same room almost always, so the pictures I took of the mixer helped a lot.
Did the sound change when properly gain-staged? Absolutely.
