Tuning: Fine Pitch Control
Pitch control makes it possible to tune the
PSR-48 over a ±50–cent range in
approximately 3-cent 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 PSR-48 to match other
instruments or recorded music.
Press the PITCH button to tune up,
or the PITCH button to tune down. The
selected degree of tuning will be displayed
on the VOICE/ PITCH/ TRANSPOSE/
VOLUME display while the PITCH or
button is pressed, and for
approximately 3 seconds after either
PITCH button is released.
The tuning range is from –16 to 16, with
–16 corresponding to downward tuning
by
approximately
50
cents (one quarter tone),
and 16 corresponding to upward tuning by
approximately 50 cents.
0 is the "normal" pitch value, at which the
A3 key (the A above middle C) produces
"concert pitch": 440 Hertz. The normal
pitch value (0) can be recalled at any time
by pressing both the PITCH
and
buttons at the same time (the pitch value
is automatically set to 0 whenever the
power switch is turned ON).
