Logic Pro Tuner utility and plug-in
You can tune instruments connected to your system with the Tuner utility or plug-in. This
ensures that external instrument recordings are in tune with any software instruments,
samples, or existing recordings in your projects.
Tuner parameters
• Graphic Tuning display: Indicates the pitch of the note in cents. At the centered (12
o’clock) position, the note is correctly tuned. If the indicator moves to the left of center,
the note is flat. If the indicator moves to the right of center, the note is sharp. Color is
also used to indicate tuning accuracy, with green denoting a tuned signal, and orange
indicating a detuned signal.
• Reference Tuning field: Drag vertically to set the pitch of the note used as the basis for
tuning. The default is for note A at 440 Hz and can be set in a range from 410 to 470 in
0.1 Hz steps.
• Keynote display: Shows the target pitch of the note being played (the closest
tuned pitch).
• Tune Deviation display: Shows the tuning deviation in cents.
• Mute button: Silence the active channel.
• View pop-up menu: Choose a Horizontal or Vertical display and set a size.
Note: You can also set a size by dragging the lower corners of the plug-in window.
Use the Tuner utility

3. Adjust the tuning of your instrument until the indicator is centered in the Graphic Tuning
display and the Tune Deviation field shows zero (0 cents).
