Pitch effects
Logic Pro Pitch effects overview
You can use the pitch effects to transpose or correct the pitch of audio signals. These
effects can also be used for creating unison or slightly thickened parts, or even for
creating harmony voices.
You can also define a scale to automatically correct some, but not all, sung notes in a vocal
performance, for example. This enables you to effectively perfect an imperfect vocal take.
You can also use pitch correction effects creatively, modifying all pitched notes in a
performance to a single pitch or a particular key.

Pitch Correction effect
Logic Pro Pitch Correction effect overview
You can use the Pitch Correction effect to fix the pitch of incoming audio signals.
Improper intonation is a common problem with vocal tracks, for example. The sonic
artifacts that can be introduced by the process are minimal and are almost silent when
making moderate corrections.
Pitch correction works by accelerating and slowing down the audio playback speed,
matching the input signal (sung vocal) with the correct note pitch. If you try to correct
larger intervals, you can create special effects. Natural articulations of the performance,
such as breath noises, are preserved.
Any scale can be defined as a pitch reference (technically speaking, this is known as a
pitch quantization grid). Improperly intonated notes are corrected in accordance with
this scale.
