Take an audio track.
Double-click on the track to open the Editor
Click on Pitch & Warp
Now, let’s say you decide to lower a peak somewhere
You loose all the Pitch & Warp that was done and have to start over.

Also, If you change the overall “volume” of the track from within the editor or outside the editor, you loos again all the Pitch & Warp

It used to worked perfectly in 7.5. Actually, I kept that version when I need to work on Vari-Audio.
