Chapter 3: Auto-Tune 4 Controls
This chapter is a reference for all of the controls used in the Auto-Tune 4
interface. How these controls are used together for intonation correction is
demonstrated in Chapter 4, Auto-Tune 4 Tutorial.
If you are upgrading from Auto-Tune 3, you can probably skip ahead to
Chapter 5, New Feature Quick Start Guide.
Common Controls
The following controls and displays are visible regardless of which
operating mode is selected. Their settings affect both Automatic and...

INPUT TYPE
As a result of Antares research into the unique
characteristics of various types of audio
signals, Auto-Tune 4 offers a selection of
optimized processing algorithms for the most
commonly pitch-corrected inputs. Choices
include Soprano Voice, Alto/Tenor Voice, Low Male Voice, Instrument, and
Bass Instrument. Matching the appropriate algorithm to the input results in
even faster and more accurate pitch detection and correction.
To select the desired Input Type, click on the Input Type pop-up...

ANOTHER NOTE: Auto-Tune 4 will only pitch correct true stereo tracks.
If the second track (i.e., the track not selected as a pitch reference) is
simply an independent unrelated track, unpredictable (and potentially
unpleasant) sounds may result. On the other hand, something interest-
ing might happen. You never know.
When Auto-Tune 4 is instantiated on a mono track, this control is inactive
(grayed out).
BYPASS
Auto-Tune 4 does not include a dedicated Bypass control as that function is
typically...

16
ANOTHER NOTE: Some host applications allow Auto-Tune 4 to display
all tracked pitch information at their correct times within the track. If
your application supports this capability, setting the buffer to the
length of the entire song and tracking the pitch in one pass will allow
you to quickly and easily move to each section of audio to be corrected
as necessary.
GRAPHICAL MODE COLOR SCHEMEThis setting lets you select one of
three color scheme options for the Graphical Mode Pitch and Envelope...

17
NUMBER OF UNDOS Auto-Tune 4 provides multiple Undo/Redo
capability in Graphical Mode. Select the maximum allowable number
here (up to 20). Choosing a higher number allocates more memory for
saving intermediate states.
Automatic Mode Controls
KNOBS
All of Auto-Tune 4’s continuous parameters are represented as
knobs. Depending on your preference, you can control knobs
by vertical, horizontal or radial mouse movement. Set your
preference in the Options dialog described above.

THE SCALES
Auto-Tune 4 comes with 29 preprogrammed scales. The first three scales are
equal tempered. These are the ubiquitous scales typically found in Western
tonal music. The other scales are historical, ethnic, and microtonal scales.
An in-depth discussion of these scales and their history is beyond the scope
of this manual. The interested reader will find more information in Tuning
In — Microtonality In Electronic Music by Scott R. Wilkinson, published by
Hal Leonard Books.
The following is a...

ETHNIC TUNINGS:
•Indian: This 22 tone scale is used in India to perform ragas.
•Slendro: This five-tone Indonesian scale is played by ensembles
called gamelans.
•Pelog: This seven-tone Indonesian scale is more interesting than
Slendro and is now the primary scale in Balinese music.
•Arabic 1: This 17 tone scale is the original Arabic scale adopted from
the Pythagorean scale.
•Arabic 2 (chromatic): This twelve-tone scale is the modern version of
the Arabic scale popular in Arabic music today....

20
•Carlos Gamma: This scale achieves perfect purity of the primary
intervals 3/2, 4/3 and 5/4. This scale divides the octave into 34.188
steps forming intervals of 35.1 cents.
•Harmonic (chromatic): This twelve-tone scale is created in the
partials in the fifth octave of the harmonic series. The scale degrees
that correspond to the classic just intervals are the major second,
major third, perfect fifth and major seventh.
THE EDIT SCALE DISPLAY
The Edit Scale Display is used to create custom scales or to...

21
If the scale selected in the Scale popup contains exactly 12 notes (e.g.,
Chromatic, Pythagorean, Meantone Chromatic, Just, etc.), the Virtual
Keyboard (see below) will be active and any edits to the scale notes made
in the Edit Scale Display will also be reflected on the Virtual Keyboard.
NOTE: Although Auto-Tune 4 allows setting scale note behaviors in
individual octaves, any edits made via the Edit Scale Display will affect
all octaves. To edit notes in individual octaves, use the Virtual Key-...

This phrase is in D Major and, if all
the pitch errors were no greater
than about 49 cents, would work
fine with a standard D Major scale
(D, E, F#, G, A, B, C# ). However,
the pitch error of three semitones
at the end of the last note is so
large that with B and C # present
in the Scale, as the pitch fell, Auto-
Tune 4 would see first C# and then
B as the target pitch and therefore
allow the error to remain. With C#
and B removed from the Scale,
Auto-Tune 4 continues to see D as
the target pitch for...
