I appreciate all the feedback!
After a full day messing around with AudioSuite and RTAS I think what i need to do is use the Compressor/Limiter through the AudioSuite. Just seems to work better and being clip based instead of affecting the entire track you have more control over it. RTAS as someone else mentioned seems to be sketchy.
It still seems like the FCP compressor sounds better but i’m still getting to know AudioSuite so perhaps i will figure out all of the nuances.
thanks again!
