Pitch Correction effect parameters in Logic Pro for iPad

Pitch Correction parameters

•  Root Note pop-up menu: Choose the root note of the scale.

•  Scale/Chord pop-up menu: Choose a pitch quantization grid.

• Show Pitch buttons: Show the pitch of the input or output signal, respectively, on the notes of the keyboard.

• Edit Scale and Bypass Notes buttons: Choose a mode that allows you to change the scale and/or exclude notes from pitch correction.

• Bypass All button: Quickly compare the corrected and original signals or audition automation changes.

• Keyboard: Tap a key to exclude the corresponding note from pitch quantization grids. This effectively removes this key from the scale, resulting in note corrections that are forced to the nearest available pitch (key). See Exclude notes from Pitch Correction.

• Correction display: Indicates the amount of pitch change. The marker indicates the average correction amount over a longer time period. You can use the display when discussing (and optimizing) the vocal intonation with a singer during a recording session.

• Neural Pitch Detection button: Turn on pitch detection to automatically detect the Pitch Range. You can turn it off to set the pitch range manually in the Pitch Range pop-up menu.

• Pitch Range pop-up menu and field: Choose a low or normal pitch range that is scanned (for notes that need correction). See Pitch Correction effect quantization.

  Note: When Neural Pitch Detection is turned on, it is not necessary to set Pitch Range manually.

•  Response knob and field: Determine how quickly the voice reaches the corrected destination pitch.

  Singers use portamenti and other gliding techniques. If you choose a Response value that’s too low, seamless portamenti turn into semitone-stepped glissandi, but the intonation is perfect. If the Response value is too high, the pitch of the output signal won’t change quickly enough. The optimum setting for this parameter depends on the singing style, tempo, vibrato, and accuracy of the original performance.

• Tolerance knob and field: Set a zone around the core frequency where no correction takes place. A low value results in more extreme or faster corrections, and higher values allow for more pitch variation (for example, vibrato) to happen before any correction is applied.

• Global Tuning button: Turn on to use project Tuning settings for the pitch correction process. Turn off to manually set tuning with the Reference parameter. See Use Pitch Correction reference tuning.

• Reference pop-up menu: Set the reference tuning in cents (relative to the root).

• Detune knob and field: Detune the output signal by the set value.
