Range
The Normal/Low parameter determines the pitch range that you wish to search for
notes that need correction. Simply select Normal or Low for the track. Normal is the
default range, and works for most audio material. Low should only be used for audio
material that contains extremely low frequencies (below 100 Hz) which may cause the
pitch dectection to work incorrectly. The parameter does not affect the sound. It is desi-
gned to optimize tracking in the target pitch range.
Keyboard
The central element of the plug-in is the 12-note Keyboard. The Keyboard is used to
exclude notes from the pitch quantization grid. When you first open the plug-in, all
notes of the chromatic scale are selected. This means that every incoming note will be
altered to fit the next semitone step of the chromatic scale. If the intonation of the
singer is poor, this might lead to notes being incorrectly identified, and corrected. As an
example, the singer might have intended to sing an e, but the note is actually closer to
a d#. If you don’t want the d# in the song, the d# key can be disabled on the Keyboard.
Given that the original pitch was sung closer to an e than to a d, it will be corrected so
that it becomes an e.
Note: The settings are valid for all octave ranges. Individual settings for different octa-
ves aren’t provided.
Show Input/Output
These two buttons below the Keyboard will display the pitch of the input or output
signal, respectively, on the notes of the keyboard. This provides a real time, at-a-glance
overview of either the original or corrected signal.
Programmable Scales (Root and Scale)
Clicking the Scale field allows you to select different pitch quantization grids. The scale
that is set manually (with the Keyboard) is called the User Scale. The default setting is
the Chromatic scale. The other scale names are self-explanatory. If you’re unsure of the
intervals used in any given scale, simply select it in the Scale field and check out the
values shown in the Keyboard grid. You can alter any note in the scale by clicking on
the Keyboard keys. Any such adjustments will overwrite the existing User Scale settings.
Note: There is only one User Scale per song. You can, however, create multiple User Sca-
les, and save them as Pitch Correction plug-in Settings files.
The Drone scale uses a fifth as a quantization grid, the Single scale defines a single note.
Both of these scales aren’t meant to result in realistic singing voices, so if you’re after
interesting effects, you should give both of them a try.
Root allows you to select the root note of the scale (with the exception of the User and
Chromatic Scale, where there is no root note (none)). You may freely transpose the
major and minor scales as well as the scales named after chords.
