• Graphic tuning display: Indicates the pitch of the note in the semicircular area around
the Keynote/Octave displays. 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.
The numbers around the edge of the display show the variance, in cents, from the
target pitch. The range is marked in single semitone steps for the first 6 semitones
(sharp or flat). Thereafter, larger increments are shown.
• Keynote/Octave displays: The upper, Keynote display shows the target pitch of the note
being played (the closest tuned pitch). The lower, Octave display indicates the octave
that the incoming note falls into. This matches the MIDI octave scale, with the C above
middle C displayed as C4, and middle C displayed as C3.
• Tuning Adjustment slider and field: Sets the pitch of the note used as the basis for tuning.
By default, the Tuner is set to the project’s Tuning parameter value. Drag the knob to
the left to lower the pitch corresponding to A. Drag the knob to the right to raise the
pitch corresponding to A. The current value is displayed in the field.
To use the Tuner
1 Insert the Tuner into an audio channel strip.
2 Play a single note on the instrument and watch the display. If the note is flat or sharp (of
the Keynote), the segments to the left or right of center are illuminated, indicating how
far in cents the note is off pitch.
3 Adjust the tuning of your instrument until the indicator is centered in the graphic tuning
display.
