8. Tune Function
The TUNE function, which uses much smaller incre­
ments of pitch, called cents, provides the ability to
fine-tune the instrument to another instrument. The
range is 50 cents on either side of the standard pitch.
To raise the pitch
Hold down [TOUCH] switch and press
[RECORD] switch as many times as necessary.
Each press raises the pitch by about 1 cent.
TOUCH START/STOP RECORD
U
To lower the pitch
Hold down [TOUCH] switch and press [START/
STOP] switch as many times as necessary.
Each press drops the pitch by about 1 cent.
TOUCH START/STOP RECORD

Note: One step is approximately 1 cent. The value can be
changed over a range of ±50 cents. (1 cent is 1/100
of a semitone.)
To return to original tuning
Hold down [TOUCH] switch and press
[RECORD] switch and [START/STOP] switch at
the same time to return to the normal tuning
(A4=440Hz).

Note: The tuning remains in memory even after the power
has been switched off.
9. Changing Temperaments
In recent history, musical instruments have used a
tuning system, or temperament, that divides an oc­
tave (for example, C4 to C5) into 12 equal steps, called
half-steps or semitones. Before the 19th century, how­
ever, musical instruments made use of many differ­
ent temperaments that were based on scales with dif­
ferent sized semitones.
The C-350/C-150 voices can be assigned to an alter­
nate temperament for realistic performance of early
music. The two alternate temperaments are:
• Kirnberger
# Werckmeister
Selecting the temperament
Hold down [TOUCH] switch and press either
[ORGAN] or [STRINGS] switch.
TOUCH ORGAN STRINGS
“U
Werckmeister
Kirnberger
ORGAN Werckmeister While holding down the
[TOUCH] switch, [ORGAN]
lamp on.
STRINGS Kirnberger While holding down the
[TOUCH] switch, [ORGAN]
lamp on.
To return to equal temperament, hold down [TOUCH]
switch and press the same [voice selector] again (ei­
ther [ORGAN] or [STRINGS]) so that the lamp on the
selector goes off.
Note: The temperament setting remains in effect through
all subsequent use of the instrument until you
change it or turn it off. When the power is turned
on, the instrument begins with the Equal Tempera­
ment setting.
Note: To obtain a more realistic piano sound, equal tem­
perament in the PIANO voice is not exactly equal
— the lower ranges are slightly lowered in pitch,
and the higher ranges slightly raised. The effect ap-
proximates the "stretch tuning" technique used on
acoustic pianos.
