I’m not exactly sure yet so this is just a question to see if others have found similar.
I have been mixing a project in 13, opened it in 14 and started finding some levels on my dialogue mix were coning back a few of dB hot. Went back to N13 and all sounds good. The panning laws are the same in both as is the max fader level (+12).
All my plugins appear to be engaged.
Not sure how to create the issue yet, just wanting to see if I’m the only one.
Is automation working as expected?
Perhaps the new ‘event volume’ could be of influence here?
Yep. Automation seemed to be doing its thing. I suspect you may be correct re event volume but it’s just been impossible to recreate since it happened.
I’ll keep trying.
Gotta say though, I do really like 14!
Sure all the audio stuff is great, but 4k video, what a treat! 
I found immediate level changes between 13 and 14 but got zero response to my post.
Yep, opened your session. Exactly as you describe.
Well after testing my session for a while I have found I can definitely open a project in 13 and have it play back ok and open the same project in 14 and get a different level.
It doesn’t happen every time so it’s easy to get lulled into a false sense of security.
Now to try to find out why!
