Hi Everyone 

I'm working on a movie, and I have a problem with all audio Clip. I need to apply -6db on all of them. 
The way to change gain for multiple clip is relatively easy and I made it. But I had already made sequences for each scene of the film (more than 100). The new gain doesn't apply on old sequences and to my knowledge it's impossible to refresh it. 
So I'm searching a way to apply gain on this 100 sequences which I have put in a same bin.

I'm working on Avid 2020 for Mac 

Thx for the help and have a nice day 

Any luck?

The only way i found, was to manually set -6db on each sequences.
