Pitch Control; The Pitch Display - Yamaha PDP-400 Owner's Manual

Pitch Control

16
Pitch control makes it possible to tune the PDP-400 over a 50-cent range (approximate) in
approximately 1.2-cent or 1-hertz intervals. A hundred "cents" equals one semitone, so the tuning
range provided allows fine tuning of overall pitch over a range of approximately a semitone. Pitch
control is useful for tuning the PDP-400 to match other instruments or recorded music.

To tune up (raise pitch), hold the A-1 and B-1 keys simultaneously (A-1 and B-
C B
3 3
1 are the two lowest white keys on the keyboard) and press any key between C3
and B3. Each time a key in this range is pressed the pitch is raised by approxi-
mately 1.2 cents, up to a maximum of about 50 cents above standard pitch. To
raise the pitch in 1-hertz increments press the TEMPO [ ] button instead of
the C3-B3 keys. The TEMPO [ ] button can also be used to tune down while
the A-1 and B-1 keys are held.
X
Release the A-1 and B-1 keys.
Z
To tune down (lower pitch), hold the A-1 and A#-1 keys simultaneously and
press any key between C3 and B3. Each time a key in this range is pressed the
C B
3 3
pitch is lowered by approximately 1.2 cents, up to a maximum of about 50 cents
below standard pitch. To lower the pitch in 1-hertz increments press the
TEMPO [ ] button instead of the C3-B3 keys. The TEMPO [ ] button can
also be used to tune up while the A-1 and A#-1 keys are held.
X
Release the A-1 and A#-1 keys.
Z
To restore standard pitch (A3 = 440 Hz), hold the A-1, A#-1, and B-1 keys si-

multaneously and press any key between C3 and B3, or simultaneously press
the TEMPO [ ] and [ ] buttons.
X
Release the A-1, A#-1, and B-1 keys.
* Standard pitch (A3 = 440 Hz) is automatically set whenever the POWER
switch is initially turned on.
NOTES
The approximate pitch of A3 is shown on the TEMPO display in Hertz while
the pitch control function is in operation. The total display range is from
approximately 427 hertz (-50 cents) to 453 hertz (+50 cents).
The dots to the right of each figure in the display are used to provide a general
idea of fractional pitches.
• The PITCH function does not affect the DRUMS sound.
• The TEMPO [ ] and [ ] buttons allow two-speed scrolling: press lightly to scroll
through the values slowly, or press firmly to scroll rapidly.
