current Preset. The Preset LED will flash momentarily to let you know that the new
settings are being stored. The state of the BYPASS switch is also saved with the pre-
set information so any preset can be recalled in bypass mode.
The PRESET switch and 5 Preset LEDs are designed to enhance live operation. Mo-
mentarily pushing the switch cycles through the 5 presets. Whatever Auto-Tune set-
tings were indicated when you last saved a particular preset are recalled the next time
that you go to that preset. While you are on a preset, if you change any of the Auto-
Tune settings, the change happens right away, and if you then press the STORE but-
ton the change will be remembered for the next time the preset is chosen.
Now that you know how the controls work, perhaps some explanation of what Auto-
Tune processing is doing to the audio will help.
What does it do?
The Antares Auto-Tune processing in the Auto-Tune Pre lets you choose between
real-time pitch correction and two different flavors of the Auto-Tune Vocal Effect.
Pitch Correction
Auto-Tune pitch correction works by continuously tracking the pitch of your vocal and
comparing it to the notes in the (user-customizable) scale of your song. The scale note
closest to the input pitch is identified as the target note. If the vocal’s pitch exactly
matches the target note, no correction is applied. If the vocal’s pitch varies from the
target note, either sharp or flat, the output pitch is smoothly corrected to the target
note.
Auto-Tune Vocal Effect
The Auto-Tune Vocal Effect is what is technically known as “pitch quantization”. That
is, instead of allowing all of the small variations in pitch and the gradual transitions
between notes that are a normal part of singing (and speaking, for that matter), the
Auto-Tune Vocal Effect limits each note to an exact pitch, stripping out any variation,
as well as forcing instantaneous transitions between notes.
The process of choosing the pitches to quantize to is the same as described above for
pitch correction. The difference is that, for pitch correction, the correction is done
smoothly in order to make the process as transparent as possible. For the Auto-Tune
Vocal Effect, the correction is instantaneous.
