Not all changes made to a Pro Tools session can be undone or redone using the Undo History window or undo/redo key commands.
Use "Revert to Saved" if you need to undo changes that are no longer or never were available in the undo history.
- Left click "File" on the Pro Tools menu bar then "Revert to Saved" to reverse changes you made and restore the session to how it was the last time it was saved.
