There's a thing in Logic... for over 10 years I still don't understand this... if I double-click on an audio file, it opens in the edit audio window, and then you can view Track(for Flex) & "File". But in the "File" view, if I want to remove 3-4 db in the Fonctions settings, sometimes it's grayed out and I can't do it. I thought it was the Flex, then I remove all Flex on that track but I'm still unable to edit that audio file in the Audio window... it's grayed out. So I don't know anymore and I cry.
