Undoing Edit Steps in the Sample Editor
Most Sample Editor functions are destructive, changing the files stored on your hard
drive. You can, of course, use the Undo feature if things do not go your way.
To compare (or undo) your edits with the original audio file
µ
Choose Edit > Undo (or use the corresponding key command, default
assignment: Command-Z).
To cancel a destructive edit that is taking place
µ
Press Command-Period.
The audio file will be retained in its original state, even if it appears that a portion of the
editing function has occurred.
You can configure the Sample Editor’s undo functionality in the Logic Pro > Preferences
> Audio > Sample Editor pane. For details, see
Audio Sample Editor Preferences .
Creating Manual Backups in the Sample Editor
Although the Undo History and standard Undo functions are available, it’s good working
practice to create backups before processing or editing. This provides a safety copy of
your precious audio recordings should something unexpected happen, due to a processing
error or other unforeseen event.
You can make manual backups of the file you’re editing, or replace it with a backup
version at any time—using a variety of functions.
To duplicate the audio file you’re working on
µ
Choose Audio File > Create Backup (or use the corresponding key command, default
assignment: Control-B).
This creates a copy of the audio file (with the extension .dup) in the same folder as the
source file.
To revert to a backup file
µ
Choose Audio File > “Revert to Backup” (or use the corresponding key command, default
assignment: Control-Option-Command-B).
This function completely replaces the current audio file with the backup (provided one
exists, of course).
Important: You cannot reverse this function with Undo.
To save a copy with a different name—to the location of your choice
1 Choose Audio File > Save A Copy As.
