If you load the ARA version of Auto-Tune® Pro onto duplicate (identical) audio events, pitch and time corrections you make in one instance of Auto-Tune Pro will be immediately applied to all other instances of Auto-Tune Pro that are loaded on copies of the same audio event.

If you wish to apply different pitch and time corrections with Auto-Tune Pro to identical audio events, you must either create a duplicate (copy) of the original audio file and import the duplicate file into the Studio One project as a separate audio file, or bounce the audio event as a new independent audio file and then load Auto-Tune Pro as an Event FX insert on it after.
