Note: See page 15 for how to save your settings to a regis-
tration memory.

Adding Reverb

The C-180 allows you to add reverberation to what
you play on the keyboard. The Reverb effect provides
a pleasant reverberation that gives the impression that
you are performing in a concert hall or similar space.
Note: In Orchestra mode (see page 13), the Reverb effect is
not applied to the BASS sound.
1. Press the [REVERB] button (indicator lights).
2. To cancel the Reverb effect, press the [REVERB]
button once again.
Its indicator goes dark.
Changing the Reverb level
If you like the Reverb effect but think it is too promi-
nent or too faint, here's how to change the Reverb
depth:
3. Press and hold the [REVERB] button until its indi-
cator starts flashing.
4. Use the [BASS] slider to set the desired Reverb
depth.

Selecting different tunings

Tuning the C-180
There may be times when you accompany acoustic
instruments that are difficult or impossible to tune. In
that case, use the [PITCH] control on the C-180's rear
panel to adapt the C-180's tuning to that of the
acoustic instrument.
Turn the [PITCH] control towards the " " to tune the
C-180 lower (so that the A4's frequency drops below
the default "440Hz" setting).
Turn it towards the "#" symbol to tune the C-180
higher.
Using different temperaments
Like all digital instruments, the C-180 relies on the
standard tuning system for western music, where the
distance (interval) is the same for all semitones of an
octave. This is called "equal temperament".
Not so long ago, however, other tunings were used for
performing classical western music. These tunings are
characterized by varying intervals between the semi-
tones of an octave. The C-180 allows you to select
from among five different tuning methods ("tempera-
ments"):
1. Hold down [CANCEL] while pressing one of the
following buttons:
Button combination
[CANCEL] + [M1]
[CANCEL] + [M2]
[CANCEL] + [M3]
[CANCEL] + [M4]
[CANCEL] + [SET]
See step 2 to specify the key of the selected tempera-
ment.
Mean Tone—A partial compromise of the Just Major
tuning (purer tuning than "Equal"), created to make
transposition possible. As the intervals between two
neighboring semitones depends on their pitch, this
temperament may sound out of tune to untrained
ears.
Pythagorean—Developed in ancient Greece as a
method of tuning that resolved the ambiguity of
fourths and fifths. As a result, melodies sound cleaner,
while triads may appear to be flat.
Kirnberger—This temperament is relatively tolerant
towards transposition, and can be used to play in all
keys.
Werckmeister—A combination of the Mean Tone
and Pythagorean tunings. This tuning can be used in
all keys.
Equal—With this tuning, the octave is divided into
twelve equal intervals. Regardless of the interval, very
little ambiguity is produced.
For the Mean Tone and Pythagorean temperaments,
you also need to specify the key in which you want to
play:
2. Hold down [CANCEL] and the selected [M] button
while pressing the key on the keyboard that corre-
sponds to the tonic of the desired key.
Note: When performing in ensemble with other instru-
ments, be aware that, depending on the key, there may be
some shifting of the pitch. Please tune to the other instru-
ments in the ensemble.
Note: When you play back your recorded song, it will use
the temperament that was selected at the time of recording.
This may be different from the currently selected tempera-
ment.

Using an expression pedal

In Organ mode (as well as in Orchestra mode, page
13), you can connect an optional EV-5 or FV-300L
expression pedal to the EXPRESSION PEDAL jack.
Doing so allows you to control the C-180's global vol-
ume by foot for swelling effects.
