7. Click the Make Curve button. Auto-Tune
Evo will compute a new blue curve object
from the existing pitch data as well as a
green output curve that reflects the default
Curve Retune Speed. (The new curves
may be difficult to see at first because they
may exactly overlay the red curve.) Click the
I-Beam Tool on the background of the Pitch
Graph to cancel the area selection.
8. 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 when the cursor changes
to the up-and-down arrow cursor). Drag
this straight up, stretching the curve so it is
centered around the D3 graph line.
9. Drag the Arrow tool across all of the visible
curves to select them. Then move the
Arrow Tool over the body of a correction
curve so that the cursor changes to the
horizontal bar. Click and drag the curves
straight down so they centered on the C3
graph line. The Pitch Graph should now
appear as follows:
10. Set the Retune Speed to 0 and play back
the sound. Note that the errant note is now
in tune.
To continue, here is an alternative approach to
the same pitch problem using the Line Tool.
1. Click “Select All” and then click “Cut” to
delete the curves you created in the steps
above.
2. Make sure Snap To Note is engaged and
use the Line Tool to draw a horizontal line at
C3 as shown below:
3. Set the Retune Speed to 20 and play back
the sound. Experiment with other Retune
Speeds to see their effect on the green
correction curve and to hear their effects.
Some notes:
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 loudness variations.
Therefore, trying to take an existing vibrato
and change it (say speed it up) often sounds
unnatural because the new pitch variation does
not correspond to the original (and still present)
loudness variation.
These considerations are also important when
correcting pitch. It’s rarely effective to draw in
a new pitch gesture at the desired pitch, even
though that gesture may have worked well in
another performance.
As this tutorial has demonstrated, the following
two techniques provide successful approaches
to Graphical Mode pitch correction:
•
The first technique uses the Make Curve
button to create a curve of the existing pitch,
allowing you to drag that curve up or down,
