Here’s a quick tip that may save you time and a headache. Most of the time when I am arranging in Ableton Live I create a large amount of volume automation. When I get to the final mixdown stage I watch the mixer in Session View to see if any channel is too loud or soft. Often a channel that needs an overall adjustment contains large amounts of volume automation envelope breakpoints. Instead of selecting all the automation envelope breakpoints and lowering them I add the Utility plug-in at the end of the channels device chain and lower the gain a few db.

Utility is found in the Live Device Browser in the Audio Effects folder. It can also help you with Phase issues, add or remove Stereo imaging and apply DC offset filter.
