Chapter 11 Pitch eects 222
Exclude notes from pitch correction
You can use the Pitch Correction eect’s onscreen keyboard to exclude notes from the pitch
quantization grid.
When you rst open the eect, all notes of the chromatic scale are selected. This means that
every incoming note is altered to t the next semitone step of the chromatic scale. If the
intonation of the singer is poor, this might lead to notes being incorrectly identied and
corrected to an unwanted pitch. For example, the singer may have intended to sing an E, but the
note is actually closer to a D#. If you do not want the D# in the song, the D# key can be disabled
on the keyboard. Because the original pitch was sung closer to an E than a D, it is corrected to an
E.
Note: The settings made with the Pitch Correction eect’s onscreen keyboard are valid for all
octave ranges. Individual settings for dierent octaves are not provided.
Bypass individual notes in a scale
m To exclude notes from correction, click the small bypass buttons (“byp”) above the green (black)
and below the blue (white) keys.
This is particularly useful for “blue” notes. Blue notes are notes that slide between pitches, making
the major and minor status of the keys dicult to identify. As you may know, one of the major
dierences between C minor and C major is the Eb (E at) and Bb (B at), instead of the E and B.
Blues singers glide between these notes, creating an uncertainty or tension between the scales.
Use of the bypass buttons allows you to exclude particular keys from changes, leaving them as
they were.
Tip: You will often nd that it’s best to correct only the notes with the most harmonic gravity. For
example, choose “sus4” from the Scale pop-up menu, and set the Root note to match the project
key. This limits correction to the root note, the fourth, and the fth of the key scale. Turn on the
bypass buttons for all other notes and only the most important and sensitive notes are corrected,
while all other singing remains untouched.
Bypass all pitch correction
Not all audio material can be eectively pitch corrected. In some cases, you may need to
use Logic Pro’s pitch manipulation and automation features to process a portion of an
audio performance.
m Click the bypass all button, to pass the input signal through unprocessed and uncorrected.
This is useful for spot corrections to pitch through use of automation. Bypass all is optimized for
near-instant, seamless operation in all situations.
