Tutorial 6: The Make Curve Function
This tutorial will introduce you to the Make Curve function. The Make
Curve function gives you by far the most precise control over pitch accuracy
and inflection.
1. Setup to process the file “Crowd All” through Auto-Tune 4.
2. Select Graphical Mode.
3. Press the Track Pitch button.
4. Play the “Crowd All” file.
5. Select the Magnifying Glass Tool and drag out a box on the Pitch Graph
that encloses the red curve for the “-gether” part of the last word, “to-
gether.”...

7. Click the Make Curve button. Auto-Tune 4 will compute a new yellow
curve object from the existing pitch data. (The new curve may be
difficult to see at first because it will exactly overlay the red curve.)
Click the I-beam Tool on the background of the Pitch Graph to cancel
the area selection.
8. Both anchor points of the new curve will be selected. Select the Arrow
Tool and click precisely on the left end of the curve to select only the
left anchor point (you’ll know you’re over the anchor point...

3. Set the Retune Speed to 20 and play back the sound. Experiment with
other Retune Speeds to hear their effects.
Vibratos and other pitch gestures typically occur with related loudness
gestures. Specifically, with vibratos, some vocalists produce mostly pitch
variations and little loudness variations while others produce small pitch
variations and a lot of loudness variations (the latter is often called
tremolo). Nonetheless, almost all voices seem to produce a combination of
both pitch and related...

Tutorial 7: The Make Auto Function
The Make Auto function allows you to display and edit the pitch correc-
tions that would result from specific Automatic Mode settings.
1. Setup to process the file “Crowd All” through Auto-Tune 4.
2. Select Automatic Mode and set the Key and Scale to C Major and the
Retune Speed to the default of 20.
3. Select Graphical Mode.
4. Press the Track Pitch button.
5. Play the “Crowd All” file.
6. Select the Magnifying Glass Tool and drag out a box on the Pitch Graph
that...

8. Click the Make Auto button. Auto-Tune 4 will compute a new yellow
curve object from the existing pitch data:
Assuming that this entire phrase should be centered around E3, there are
several problem spots, indicated above, where the pitch is being incorrectly
adjusted towards neighboring tones.
9. To hear the pitch corrections that would be produced in Automatic
Mode, set the Graphical Mode Retune Slider to 0, (fast) and play back
the file.
10. Switch to the Automatic...

Note how the pitch errors from the previous curve have been removed.
Also, note the “raised pitch” indicated above. This occurs because the
Automatic Mode Retune slider value of 20 is slow compared to the
rapidly increasing pitch that is occurring at that point in time. But even
with the raised pitch, the average output pitch is centered on E3 and
the phrase sounds in tune.

Chapter 5:
New Feature Quick Start Guide
This chapter brings all of the new Auto-Tune 4 features together in one
place to help experienced Auto-Tune 3 users learn the new features
without having to slog through all of the stuff they already know.
With the exception of the seriously reworked graphical editing tools
(described in detail below), most of the new features in Auto-Tune 4 are
additions to the current Auto-Tune 3 functionality. In other words, pretty
much everything that isn’t a new feature...

62
ALTERNATE: The same background color as Classic, but with blue
detected pitch curves and bright green target pitch curves (selected
for readability by people with the most common types of Red/Green
color blindness).
BLACK AND WHITE: A white background with red detected pitch
curves and black target pitch curves. Not too pretty, but the ultimate
in high contrast (as in the original Auto-Tune).
KNOB CONTROLSelect how you want to control the “knobs” in the
Auto-Tune 4 interface:
VERTICAL: Position the...

DETAILS
OCTAVE AS PLAYED/ALL OCTAVESFor both of the MIDI functions
(Learn Scale from MIDI and Target Notes via MIDI), you can now choose
whether you want incoming MIDI notes to affect all octaves (that’s how
it worked in Auto-Tune 3) or just the notes in the specific octaves in
which they are played.
DUAL DETUNE DISPLAYThe Detune control now includes dual displays
that simultaneously show the amount of detuning in cents and in Hz.
relative to A440.

VIRTUAL KEYBOARDThe Virtual Keyboard displays Auto-Tune 4’s pitch
detection range and acts both as a display of the current Scale settings
and as a tool for setting target note behaviors.
NOTE: The keyboard is only active for the Major, Minor and Chromatic
scales.
KEY COLORS: The color of the keys of the Virtual Keyboard indicate
their current state as follows:
Blue: The currently detected input pitch
White or Black: Scale Note
Brown: Bypass
Invisible: Remove
