NOTE: This function uses the same Stochastic Optimal Linear Estimation
Theory as the Auto Mode’s Improved Targeting function to attempt to
differentiate between vibrato and intended pitch changes. Therefore,
you can typically select a portion of your audio containing both vibrato
and intended pitch change and the Scale Vibrato function will scale the
vibrato while leaving the intended pitch changes alone. But again,
depending on the actual performance, sometimes this will work better
than others. If...

RETUNE SPEED
The Retune setting is used only during
the Correct Pitch process. It’s similar in
function but separate from the Retune
control in Automatic Mode.
In Graphical Mode, the target pitch is
not the scale tone nearest to the input,
but rather the yellow target pitch
curve. The Retune Speed control allows you to specify how quickly Auto-
Tune 4 will change the pitch of the input to that of the target pitch curve.
A value of zero will cause the output pitch to precisely track the target
pitch...

Chapter 4: Auto-Tune 4 Tutorial
This chapter introduces you to how Auto-Tune 4 works by guiding you
through a number of brief tutorials.
These tutorials make use of a number of audio and MIDI files. (We will
assume that you are familiar with loading audio and MIDI files into your
host application.)
If you purchased a packaged version of Auto-Tune 4, your will find the
required files in the “Tutorial Audio” folder on the installation CD ROM.
If you purchased your copy of Auto-Tune 4 via download, you...

1. In the Edit Scale Display, click the Remove buttons next to the notes B,
D, F# and G#.
2. Play “A2-A3-A2 sweep” again.
You will now hear an arpeggiated A Major triad because you have removed
all the other notes from the scale.
To continue:
1. In the Edit Scale Display, click the Bypass button next to E.
2. Play “A2-A3-A2 sweep” again.
You will now hear the effect of not correcting the E. During the time that
Auto-Tune 4 would normally be tuning the input to E, Auto-Tune 4 instead
enters bypass mode...

Tutorial 2: The Improved Targeting Function
This tutorial will demonstrate the purpose and use of the Automatic
Modes Improved Targeting function.
Begin the tutorial by doing the following:
1. Load or import “wide_vibrato” into a track of your host program. This
is a recording of a male voice singing a sustained G with a pro-
nounced vibrato. Play the track so that you are familiar with the
original audio. Despite the wide vibrato, you will notice that the
singers pitch drifts alternately sharp and...

A red curve will appear in the Pitch Graph. This is the pitch contour of
wide_vibrato.
7. Click the Make Auto button. A yellow curve will appear. This curve
represents the pitch correction that would result from processing the
audio with the current Automatic Mode settings. Note all the instances
in which Auto-Tune 4 identifies G# or F#as the target pitch.
8. Set Auto-Tune 4 back to Automatic Mode.
9. Set Improved Targeting to On.
10. Return once again to Graphical Mode.
11. Click Make Auto (there is...

8. Set the Retune control to 20 and play the audio track using this scale.
NOTE: You can also instantaneously define a scale by playing all of the
notes of the scale as a chord (i.e., all scale notes played on the same
beat) and recording that into a MIDI track. This is an ideal way to use
Auto-Tune 4 in music with many key (scale) changes.
With Target Notes Via MIDI, Auto-Tune 4 looks at its MIDI input in real time
to determine its current target note(s). Try the following with the provided
audio and...

5. Set Auto-Tune 4 to Graphical Mode.
6. Click the Track Pitch button.
7. Play the sweep signal through Auto-Tune 4.
8. Stop playback (depending on your host application, you may also have
to click the Track Pitch button again to stop the tracking function).
A red curve will appear in the Pitch Graph. This is the pitch contour of
the sweep signal.
To continue:
1. Select the Magnifying Glass tool and drag out a box on the Pitch Graph
that encloses the red curve. The result will be something like the...

To erase the last point entered, press  on the keyboard (you
can press  repeatedly to erase back to the first anchor point).
3. Set the Retune Speed to 0. Click the Correct Pitch button and play back
the sound to hear the effect.
4. Select the Curve tool and create a curve similar to the one shown
below. Click and hold the mouse button and drag to draw the curve.
When done, release the mouse button.
5. Press Correct Pitch and play back the sound to hear the effect.
6. Vary the Retune Speed between 0...

13. Select the Scissors Tool and click on an existing line or curve to break it
in two at that point. A stacked pair of anchor points will be created at
the point you click. Select the Arrow Tool again and use it to drag each
of the new end points in turn to new positions.
14. Select one or more objects and play with the Edit Buttons (Undo, Cut,
Copy, Paste, Select All).
This would also be a good time to see if the Edit Button keyboard equiva-
lents work in your host application:
