About the backup battery
This product contains a backup battery that prevents the
contents of internal memory from being lost when the
power is turned off. If the [TOUCH] switch indicator
blinks when the power is turned on, the battery must be
replaced. Please contact a nearby Korg dealer or a Korg
service center.
❍ When you press the [TOUCH] switch, it will stop
blinking.
About Recorder data
Since it is possible for the contents of memory to be
accidentally lost, you should save important data on an
external data filer (storage device) etc. (ꢀp.21).
Korg will accept no responsibility for any damages that
may result from loss of data.

Main features
Parts of the C-4500 and their function
A wide variety of sounds
(ꢀp.11)
Six different expressive and high-quality sounds,
including a concert grand piano, are produced by
Korg's proprietary HI (Hyper Integrated) synthesis
system. You can use the Layer or Split functions to play
two sounds simultaneously.
Effects
(ꢀp.11)
The C-4500 provides built-in digital effects that can
simulate the reverberation of a concert hall or add rich
spaciousness.
Pedal effects
(ꢀp.12)
1
C
The C-4500 has the same three pedals as on an acoustic
piano: damper, sostenuto, and soft. The damper pedal
of the C-4500 also simulates the resonances that occur
in the strings of an acoustic piano. The damper pedal
and soft pedal allow half-pedaling techniques, where
the amount of effect can be adjusted by the depth with
which you press the pedal.

Metronome function
(ꢀp.13)
The built-in metronome allows you to adjust the time
signature, tempo, and volume, and even use a bell
sound as the accent.
Recorder function
(ꢀp.17)
The built-in recorder lets you record and play back your
performance as easily as when using a tape recorder.

1 [POWER] switch
This switch turns the power on or off. Each time you
press it, the power will be turned on or off. (ꢀp.7)
You can choose from three different settings to adjust
how the sound will respond to your keyboard playing
dynamics.
2 [MASTER VOLUME] slider
This slider controls the volume that is output from the
speakers, headphones, and outputs. (ꢀp.7)
Temperaments
(ꢀp.15)
In addition to equal temperament, the C-4500 allows
you to select two classical temperaments (Kirnberger
and Werckmeister) for historically accurate perfor-
mance of classical music.
3 [BRILLIANCE] switch
This switch sets the brightness of the sound. (ꢀp.11)
4 [REVERB] switch
This switch applies reverberation to the sound (ꢀp.11).
Adjustable pitch
(ꢀp.15)
5 [CHORUS] switch
This switch adds spaciousness to the sound (ꢀp.10).
The Transpose function lets you change the pitch of the
piano, and the Pitch Control function allows you to
make fine adjustments in the tuning.
6 [TRANSPOSE/FUNCTION] switch
This switch is used to make MIDI-related settings
(ꢀp.20), and to transpose the pitch (ꢀp.14). It is also
used to make various other settings.
MIDI capability
(ꢀp.19)
The C-4500 supports MIDI, the standard that allows
musical data to be transferred between musical instru-
ments and computers. MIDI allows two or more
devices to control or be controlled by each other, and
also allows you to use the C-4500 as a 16-part multi-
timbral tone generator.

4. Adjust the volume.
Preparations for playing
Use the [MASTER VOLUME] slider to control the
volume that is output from the built-in speakers,
the headphone jack, and the rear panel [OUTPUT]
jacks.
Before you begin playing
1. Plug in the power cable.
Plug the power cable into an outlet.
Make sure that the AC outlet is the correct
voltage for your piano.
Raise the [MASTER VOLUME] slider to the
middle position. The volume will increase as you
move the slider toward the right, and will decrease
as you move it toward the left. At the “0” position,
there will be no sound.
2. Open the keyboard cover.
Lightly lift the center of the front edge, and
support it as you slide the cover gently away from
yourself.
While playing the instrument, adjust the volume to
an appropriate level.
When using headphones
Insert the plug (1/4" phone plug) of your stereo
headphones into the headphone jack located at the left
side of the bottom panel of the instrument.
If headphones are plugged in, no sound will be output
from the built-in speakers.
Use headphones when you do not wish to be heard by
those around you, such as when playing at night.
Since two headphone jacks are provided, you can
enjoy playing together with another person.
To close the keyboard cover, lightly lift the center
of the front edge, and slide it toward yourself.
Be careful not to pinch your fingers or hands when
opening or closing the keyboard cover.
The cover may be damaged if you apply excessive
force or open it roughly.
When opening the keyboard cover, make sure that
no objects such as papers or coins are resting on top
of the keyboard cover. Such objects may fall into the
instrument.
3. Turn on the power.
Press the [POWER] switch to turn on the power.
When using headphones, protect your hearing by
avoiding extended listening at high volumes.
If your headphones have a mini ¡ phone jack
conversion plug, grasp the conversion plug when
plugging in or unplugging the headphones.
When using the music stand
Raise the music stand, and use the two stoppers
located at the back to prevent it from falling over.
When the power is turned on, the power indicator
located at the left side of the piano will light.
To turn off the power, press the [POWER] switch
once again.
When the power is turned off, the power indicator
located at the left side of the piano will go dark.

light to indicate the current brilliance setting.
Playing two sounds together (the Layer
function)
Adding reverberation
You can add reverberation and depth to the sound
currently selected by the [Sound selector] switches, to
create a sense of presence as though you playing in a
concert hall. This is called the reverb effect.
The reverb effect can be set independently for each
sound. This setting is remembered for each sound until
you change it.
You can cause two sounds (for example [PIANO 1]
and [STRINGS]) to be heard simultaneously when
you play a note. This is called the Layer function.
1. Simultaneously press two [Sound selector]
switches.
The indicators of the two [Sound selector] switches
you pressed will light. Up to 32 notes can be
played simultaneously. (Up to 21 notes if PIANO 1
is selected.)
1. Hold down the [REVERB] switch, and press
either the [PIANO 1/L], [PIANO 2/M], or
[E.PIANO/H] sound selector switch to select the
depth of reverb.
2. To turn off the Layer function, press a single
[Sound selector] switch.
Adjusting the volume balance of the two sounds
PIANO 1/L
PIANO 2/M
E.PIANO/H
Shallow reverb will applied.
Moderate reverb will be applied.
Deep reverb will be applied.
❍ While holding down the [Sound selector] switch
for the instrument you wish to reduce the
volume of, repeatedly press the [Sound selector]
switch for the instrument you wish to increase
the volume of.
2. To check the currently selected reverb depth,
hold down the [REVERB] switch.
The indicator of either the [PIANO 1/L], [PIANO
2/M], or [E.PIANO/H] sound selector switch will
light to indicate the current reverb depth.
When you have set the desired balance, use the
[MASTER VOLUME] slider to adjust the volume.
3. If you do not want to apply reverb, press the
[REVERB] switch.
Reverb will be turned off, and the [REVERB]
switch indicator will go dark.
The volume balance is remembered even after the Layer
function is cancelled, and after the power is turned off.
MeMO
Since the [PIANO 1] and [PIANO 2] sounds simulate the
string resonance of an acoustic piano, a small amount of
reverb will remain even if reverb is turned off.
