If, on the other hand, your signal is noisy or not
well-isolated (as might be more common in a
live performance situation) or you are dealing
with a particularly breathy or guttural voice,
it may be necessary to allow more signal
variation (higher Tracking numbers). However,
under these circumstances tracking is not
guaranteed and a too “relaxed” setting may
introduce distortion and popping.
NOTE: The improved pitch detection
technology in Auto-Tune 7 (in
combination with the Input Type
selection described above) results in noticeably
more reliable pitch detection compared to
previous versions of Auto-Tune. If you have
used older versions of Auto-Tune, you may find
that situations that previously required constant
modifications of the Tracking control now track
perfectly at the default setting.
Select Pitch
Reference
Auto-Tune 7 provides
the ability to pitch
correct stereo tracks
while maintaining the tracks’ phase coherence.
(Refer to your host application’s manual for
instructions on assigning a plug-in to a stereo
track.) Click the appropriate button to select
which of the two stereo tracks (left or right)
Auto-Tune 7 will use as a pitch reference.
NOTE: If there is a marked difference
in the two tracks, pick the cleanest,
most isolated track. For example, if
one track is a close mic’d vocal while the other
is mic’d from farther away for ambience, or is
heavily processed, select the close mic’d track.
ANOTHER NOTE: Auto-Tune 7 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 interesting might
happen. You never know.
When Auto-Tune 7 is instantiated on a mono
track, this control is inactive (grayed out).
Key Selection
This control lets you select the
key of the track you plan to
process.
To select the desired key, click
on the Key pop-up and then select the desired
note from the pop-up list. This determines the
pitch of the first note of the scale according to
the standard A3 = 440 Hertz.
Scale Selection
This control is used in
combination with the Key
selection above to define
the scale of the track you
plan to process.
To select a scale, click on the Scale pop up and
then select the desired scale from the pop-up
list.
NOTE: To avoid having to deal with
scales containing those annoying
double flats, double sharps and
notes like Cb, E#, Fb and B#, Auto-Tune 7
will automatically choose the simpler of two
enharmonically equivalent scales. For example,
if you select Db Major, the Edit Scale Display
will duly display the Db Major scale. However,
if you then go to the Scale selection pop-up
and select Minor, the Key will automatically be
changed to C# and the Edit Scale Display will, in
fact, display the much friendlier C# Minor scale.
This will be reflected on both the Auto Mode
Scale Edit display and the Pitch Graph Display in
the Graphical Mode.
Auto-Tune 7 comes with 29 preprogrammed
scales. The first three equal-tempered scales,
chromatic, major, and minor, are the ubiquitous
scales typically found in Western tonal music.
The other scales are historical, ethnic, and
micro-tonal 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 —
Micro-tonality In Electronic Music by Scott R.
Wilkinson, published by Hal Leonard Books.
A brief description of each scale can be found
in Chapter 6, The Auto-Tune 7 Scales.
