The Key and Scale allows you to set the notes your audio will be tuned to. For the best results, set them to match the actual key and scale of your music.
The Keyboard is automatically updated to show which notes are active for the current Key and Scale selection. You can also use the keyboard to turn individual notes on and off.
If you’re not sure what key your music is in, you can use the Auto-Key (available for USD $2.49/month) to automatically detect it and send that information to Auto-Tune Access.
