A Retune Speed control lets you match the retune rate to virtually any performance style. For most common pitch problems, Auto-Tune Evo's Automatic Mode instantaneously detects the pitch of the input, identifies the closest pitch in a user-specified scale (including minor, major, chromatic and 26 historical and microtonal scales), and corrects the input pitch to match the scale pitch. All with a user-interface that is a model of clarity, speed and ease-of-use.
