Scales

The heart of Automatic Mode pitch correction is the Scale. Auto-Tune 3

lets you choose from major, minor, chromatic or 26 historical, ethnic and

microtonal scales. Individual scale notes can be bypassed, resulting in no

pitch correction when the input is near those notes. Individual scale notes

can also be removed, allowing a wider range of pitch correction for

neighboring pitches. The scale can be de-tuned, allowing pitch correction

to any pitch center.

For added flexibility, you can also select the target pitches in real time via

MIDI from a MIDI keyboard or a pre-recorded sequencer track.

Retune Speed

Auto-Tune 3 also gives you control over how rapidly, in time, the pitch

adjustment is made toward the scale tone. This is set with the Retune

Speed control (see Chapter 3 for more details).

• Fast Speed settings are appropriate for short duration notes and for

mechanical instruments, like an oboe or clarinet, whose pitch typically

changes almost instantly. A fast enough setting will also minimize or

completely remove a vibrato, as well as produce the infamous “Cher

effect.”

• Slow Speed settings, on the other hand, are appropriate for longer

notes where you want expressive pitch gestures (like vibrato) to come

through at the output and for vocal and instrumental styles that are

typified by gradual slides (portamento) between pitches. An appropri-

ately selected slow setting can leave expressive gestures intact while

moving the average pitch to the correct tonal center.

Vibrato

Auto-Tune 3 can also apply a vibrato to the input sound. You can program

the vibrato depth, vibrato rate and the onset delay of the vibrato. You can

also choose the shape of the pitch variation in the vibrato (sine, square or

sawtooth). By combining a fast Retune Speed setting with Auto-Tune 3’s

Vibrato settings, you can even remove a performer’s own vibrato and

replace it with Auto-Tune 3’s programmed vibrato, all in real time. Also,

unusual combinations of Vibrato Waveform, Rate and Depth settings can

be used for some interesting special effects.
