Varispeed can transpose the Key/Scale parameter of all AutoTune plugins in your project.

The supported plugins are:
- Antares Auto-Tune (Access, Artist,Pro)
- Waves Tune Real-Time
- Nectar (3, 4, and the Pitch plugin)
- MetaTune
- Melda MAutoPitch
- Melodyne
- AutoTuna
- Xpitch
And of course the built in AutoShift works too without enabling anything. : )

Some notes for specific AutoTune plugins:
- Antares Auto-Tune (Access, Artist, Pro):

- Waves Tune Real-Time:
The AU, and VST/VST3 versions are built differently and require different methods to transpose them. Choose your format from the list.
- Izotope Nectar (3, 4, and Pitch):
The AU, and VST/VST3 versions are built differently and require different methods to transpose them. Choose your format from the list.
- Melodyne:
Since there’s no ARA implementation in Live 11 and 12 (yet), when you change your project’s tempo, Melodyne can’t follow it correctly, and it’ll play the audio from its timeline in the wrong position.
To prevent that when you enable Melodyne transposition the Tempo circuit of Varispeed will be automatically disabled.
Note: Varispeed can only transpose these plugins if their Key parameter is visible in Live.
Check the Serato section to see how to configure them.
