Forty different and expressive high-quality sounds, including
a Stereo Concert Grand Piano. You can use the Layer and Split
functions to simultaneously play a combination of two
sounds. Sounds and sound combinations can be freely modified.
Performances
Sound combination can also be saved into performances, giving you an additional set of 30 timbres (3 banks of 10 performances). Performances also store a custom split point, for
custom combinations of sounds over the keyboard.
Four zones keyboard
The new high-quality, realistic Korg RH3 keyboard features
four zones with different weights. This gives you the same realism and feeling as a grand piano keyboard.
Touch control
You can choose from nine different settings to adjust how the
sound will respond to your keyboard playing dynamics.
Pedal effects
The C-720 provides the same three pedals as a grand piano,
controlling the soft, sostenuto, and damper functions respectively. The damper pedal simulates the natural string resonances and noises of an acoustic piano, by means of the
innovative Korg EPx (Piano eXperience) technology. Both the
damper and soft pedals let you vary the amount of the effect by
how far you press down on them (“half-pedal” function). In
addition, pedals can be freely assigned to other functions, like
starting the recorder or changing the speed of the rotary speaker.
Piano eXperience (or EPx) effects are particularly evident in
sounds like GrandPiano, BriteGrand and MelloPiano.
One-hundred eighty-five songs
The C-720 includes a huge library of songs, based on famous
pieces and lesson books. These songs are perfectly suitable for
piano lessons, being recorded into two separate parts (left
hand on Part 1, right hand on Part 2) that you can easily turn
off and play on the keyboard. In addition, you can change the
metronome’s tempo and let a defined passage play in cycle.
SongBook included
The SongBook album is also included as a printed music book
– a great resource for practicing and playing along with your
preferred tunes.
Onboard recorder
A multi-track, easy-to-use onboard recorder, lets you record
your own songs, or read Standard MIDI Files that you can
transfer via the integrated USB port from an external computer.
Metronome
The built-in metronome allows you to select the time signature, tempo, and volume, and use a bell sound as the accent. It
can even give you a drum accompaniment in a musical style of
your choice (drum patterns).
Data transfer via USB
When connected to a personal computer via the USB port, the
C-720’s internal memory can be seen as a USB disk. This way,
you can backup your data, or transfer files between the C-720
and the personal computer.
Piano eXperience
While existing piano sampling techniques have resembled an
audio snapshot, our new “Piano eXperience” technology is
more of a hologram, accurately reproducing every dimensional detail of the sound. All piano sampling for the C-720 is done
in stereo to preserve the natural imaging of the sound. Different dynamic levels are captured to extend the instrument's expressive vocabulary.
Going even further, the C-720 uses the sound of the key being
released and the hammer returning, as well as the sympathetic
damper resonance of the strings to create all of the subtle shadings that create a superior instrument sound. This attention to
detail defines the sound of the new C-720, providing an instrument that can interpret every nuance of touch into a meaningful musical gesture.
4
MIDI capabilities
The C-720 supports the MIDI protocol, the standard that allows music data to be transferred between musical instruments and computers. MIDI allows two or more devices to
control or be controlled by each other, and also allows you to
use the C-720 as a 16-part multitimbral tone generator.
MIDI over USB
The USB port also carries MIDI data, so that you can connect
the C-720 directly to your personal computer with a single cable and without the need of a dedicated MIDI interface. A dedicated KORG USB MIDI Driver is freely available for full use
of the C-720’s MIDI features.
Introduction
> Main features
Temperaments
In addition to the Equal temperament, the C-720 allows you to
select nine alternative temperaments, for historically accurate
performance of classical music, or experimenting. When selecting an acoustic piano sound, the typical Stretched Tuning
is automatically selected.
Adjustable pitch
The Transpose function lets you change the pitch of the piano,
and the Master Tuning function allows you to make fine tune
adjustments.
Effects
The C-720 provides built-in digital effects that can simulate
the natural ambience of a concert hall (reverb) and add richness to the sound (chorus). In addition, each sound includes
an insert effect (delay, phaser, equalizer, rotary speaker,
etc…), that is specially suited to each particular sound.
Powerful integrated amplification
The C-720 includes a powerful, 2 × 35 Watt, plus 2 × 12 Watt
double stereo amplifier, with two woofers in closed box and
two dome tweeters. This gives the most authentic sound reproduction, together with enough volume to deliver the full
power of an acoustic piano.
Two sets of headphones
You can connect two stereo headphones, to play with your
teacher or another musician. Connecting a headphone set automatically disconnects the speakers, so there is no risk to disturb others when practicing by night.

The C-720 has three assignable pedals, usually acting as damper, sostenuto, and soft. However, you can assign the pedals different functions (see page 44 for sound-level assignment, or
page 49 for global programming).
With the default settings, you can use these pedals to add expression to your playing, as on a traditional piano.

Soft
Sostenuto
Damper
(1) Damper pedal
The damper pedal simulates the natural string resonances of
an acoustic piano. Pressing this pedal will sustain the sound,
Transposing
producing a richly resonant decay. You can control the damper’s depth by how far down you press on the pedal (“half-pedaling”).
Sounds like GrandPiano, BriteGrand and MelloGrand also
trigger EPx effects while in Single and Split mode. However,
these effects are not available when you are in Layer mode.
(2) Sostenuto pedal
Pressing this pedal will apply the damper effect only to the
notes that are already being held down on the keyboard, and
will sustain only those notes. The damper effect will not be applied to any additional notes that you play while holding down
the Sostenuto pedal (apart for the notes already held).
(3) Soft pedal
Pressing this pedal will make the tone softer. You can control
the soft effect depth by how far down you press on the pedal
(“half-pedaling”)
In some cases, a song may be written in a difficult key (e.g.,
many black keys), or you may wish to shift the pitch to match
another instrument or vocalist. In such cases, you can transpose (shift the pitch) so that you can use an easier fingering, or
use the same familiar fingering to play at a different pitch. This
is called the Transpose function.
16
For example if you transpose upward by one semitone, playing
the notes shown at the lower left will produce the pitches
shown at the right.
Basic functions > Changing the brilliance
Note: When the instrument is turned on, transposing is reset.
1. Press the TRANSPOSE button to show the Transpose dis-
play:

If you do no changes, just wait some seconds for the page
to automatically disappear. Otherwise, you can exit from
this page by pressing the EXIT button.
Changing the brilliance
Brilliance is the sound’s brightness, that may be affected by the
sound of the room the piano is placed into. For example, a
heavy carpeted room sounds duller than a room containing
less carpeting or furniture. You can set an overall increase or
decrease of brilliance for all sounds.
This is the same parameter you can change in the Brilliance
page of the Global mode (see page 48). However, contrary to
the changes you can make in the Global mode, the changes
made with this button cannot be memorized, and are reset
when turning the instrument off.
Note: When the instrument is turned on, brilliance set in this
page is reset. (Brilliance may have permanently been set in Global mode, see page 48).
1. Press the BRILLIANCE button to show the Brilliance dis-
play:
2. Use the +/YES and -/NO buttons to change the transpose
value in steps of one semitone, within a range of ±11 semitones. When a transposition is active, the indicator turns
on.
3. Press the EXIT button to exit from this page.
4. Press the TRANSPOSE button again to turn transposition
off. The indicator will turn off.
5. Press the TRANSPOSE button if you want to turn transpo-
sition on again, with the last value selected. The indicator
will turn on again. Wait some seconds for the page to disappear, or press the EXIT button to exit immediately.
If you do no changes, just wait some seconds for the page
to automatically disappear. Otherwise, you can exit from

Turning the effects on/off
The C-720 has two global effects (reverb and chorus), in addition to an insert effect for each sound (see diagram on
page 41). The reverb simulates the sound reverberation in a
room, while the chorus simulates a modulating effect that
makes the sounds richer.
The insert effect is part of the sound itself, and should remain
on to avoid a dramatic change in timbre. On the contrary, you
can turn the reverb and chorus on/off as you like, by using the
REVERB and CHORUS buttons on the control panel.
However, selecting a different sound will reset the status of the
buttons, since it is saved with the sound itself. To permanently
change the effect’s status, edit the sound by keeping one of
these buttons pressed for a couple seconds. See page 41 for
more details.

Using performances
Performances are registrations of sound combinations. Instead of selecting single sounds, or a combination of sounds,
you simply select a performance. A performance then recalls
one or two sounds, each one with their own settings, plus the
memorized split point (if the sounds are in Split mode).
There are 30 performances (10 groups
× 3 banks each). Each
group corresponds to one of the numbered sound select buttons (1 ~ 10). You can then choose one of the three banks inside the selected group by using the VARIATION button
(more details are on page 70).

** Note: Performance 30 (PnoExpDEMO) is designed to demonstrate our “Piano eXperience” technology, by exaggerating the
amount of key-off/hammer return portion of the Grand Piano
sound; it is not intended to be a play-able timbre. Normally,
these additional Piano eXperience sounds are not perceived as
separate elements, but together with the other sample layers,
they are a vital part of the realism and the authentic piano tone.
Here is how to choose a performance.
Note: While in Performance mode, you cannot switch between
Single, Layer and Split modes. However, if you select a performance with two sounds in Split, the SPLIT indicator will turn on.

Drum patterns
Instead of an ordinary time signature (4/4, 3/4, etc…), a drum
pattern can be assigned to the metronome. This will give you
the sense you are playing together with a real drum player. You
can also record a drum pattern into a song.
Note: Contrary to ordinary metronome “clicks”, drum pattern
notes can also be recorded by the internal recorder. They can
also be transmitted via MIDI, so you can record them on an external sequencer, or make them play with an external instrument (see “MIDI” on page 56).
Drum patterns are in the second half of the time signature list.
While the list is selected, either scroll to it, or press both the +/
YES and -/NO buttons together, to quick jump to the drum
patterns. Press these buttons together again to quick jump to
the ordinary time signatures (4/4 selected).

Playing back a song
Playing back a song > Accessing the Song Play mode
The C-720 incorporates a multitrack recorder, with which you
can record and play back songs. Since you can turn off a single
part (say, the left hand), and leave another part playing (say,
the right hand), this can be very useful for practicing.
Together with the C-720 come a huge number of classical
songs (185), with which you can play along for practicing or
for enjoying your preferred tunes. Songs are organized in “albums”, that include famous lesson books (Beyer, Burgmüller),
a collection of famous songs, and all the pieces included in the
supplied SongBook.
The recorder can also read 16-track songs in the Standard
MIDI Files (SMF) format, that can be created on a computer
or easily found on the market or in the public domain. Please
note that, while the C-720 complies with General MIDI (GM)
sound mapping, it does not include all GM sounds. For a detailed list of sounds, see page 68.
