Auto-Tune Pro AAX Native PC Notes Installation The Auto-Tune Pro installer will automatically install the plug-in in the correct location, and no reboot of the computer will be necessary. Authorization Auto-Tune Pro 9.1.0 now supports machine authorization using the Antares Central app, and does not require an iLok dongle. Each license may be activated on up to two computers at a time. If you’re updating from a previous version, which used iLok, you will need to re-authorize using Antares Central. For authorization instructions, please see the “Authorizing Auto-Tune Pro” document included with the installer, or view video instructions h ere. Pro Tools Compatibility Auto-Tune Pro requires Pro Tools 11.3.1 or later. Backwards Compatibility Auto-Tune Pro 9.1.0 can load previously saved settings from Auto-Tune Pro 9.0.x and 8.1.x, but not earlier versions of Auto-Tune. Forwards Compatibility Forwards compatibility from earlier versions is not supported. If you save a session with version 9.1.0 you will not be able to load its settings with any previous version of Auto-Tune. For this reason, we recommend NOT updating to this new version if you're in the middle of a project or exchanging session files with others using earlier versions of Auto-Tune Pro.
