Antares Auto-Key 2  From Antares

Effortlessly synchronize all the Auto-Tune plug-ins in your track with the Auto-Key 2 software plug-in from Antares. Auto-Key 2 will analyze your lead vocal track, determine the key, and lock all the other instances of Auto-Tune to the same key, making it easy to ensure all your tracks are perfectly in tune. You can also adjust the pitch reference based on the deviation from the standard A440 using the pitch reference display and the Detune control. In addition, the software detects the key and scale of a track outside of your session in seconds, a terrific tool for a DJ looking for tracks in the same key. Auto-Key 2 runs on Mac and Windows computers on the AAX native, AU, and VST3 platforms.

How Does It Work?

If on your project you have multiple Auto-Tune plug-ins opened on separate tracks, you'll see they're all set to the standard C chromatic key. Add Auto-Key to the original vocal track to find the correct scale and key. After playing the track for a few seconds, Auto-Key will display the key. The final step is to click on Send to Auto-Tune to update all the instances of Auto-Tune in use. Auto-Key uses TONART V3 by zplane.development as an automatic key detection engine.
