THANKYOU FOR PURCHASING A KAWAI DIGITAL PIANO!  
This KAWAI digital piano is a revolutionary new keyboard instrument, combining the latest in electronic advances with  
traditional craftsmanship inherited from KAWAI’s many years of experience building fine pianos. The CN31 keyboard  
provides the touch response and full dynamic range required for a superb performance of piano, harpsichord, organ, and  
other instruments. The CN31’s Lesson function helps performers to practice the piano with a collection of etudes from  
Czerny and Burgmüller, or songs from Alfred’s Basic Piano Library and Alfred’s Premiere Piano Course lesson books (USA,  
Canada, Australia and UK only).  
In addition, the CN piano is equipped with reverb and digital effects processors, providing an unrivalled richness of sound.  
Industry standard MIDI (Musical Instrument Digital Interface) jacks are included, allowing a number of other electronic  
instruments to be controlled and played simultaneously, creating a range of musical possibilities.  
This Owner's Manual contains valuable information to help performers make full use of the instrument's many capabilities.  
Please read all sections carefully and keep this manual handy for future reference.

5) EFFECTS/REVERB  
When selecting some preset sounds, the LED indicator for the EFFECTS or REVERB buttons may turn on  
automatically. This is because certain preset sounds are prepared with an effect enabled as their default setting.

Delay is an effect that adds echoes to the sound. There are three types of delay available (delay 1, delay 2 and  
delay 3), each with a different length of delay between the echoes.  
¡ TREMOLO  
This is a vibrato type effect.  
¡ ROTARY

7) TRANSPOSING THE PIANO  
The transpose function allows the piano’s keys to be raised or lowered in half steps. This is particularly useful  
when accompanying instruments with different tones, or when a song learned in one key must be played in  
another key. The transpose feature allows the song to be played in the original key, but heard in another key.  
Step1  
Press and hold the TRANSPOSE button. While holding the TRANSPOSE button, use the VALUE buttons  
or the keyboard keys from C2 to C4 to specify the transposition amount.  
2
Hold down the button.  
The display will show a number indicating how many half steps up or down the piano has been transposed.  
‘-5’, for example, represents a transposition that is 5 half steps lower.  
‘0’ indicates no transposition.  
Each time the VALUE S button is pressed, the transpose value is increased by one half step, while each time  
the VALUE T button is pressed, the transpose value is decreased by one half step.  
The piano can be transposed by up to 12 half steps higher or 12 half steps lower.  
The ‘C’ key at the middle of  
the keyboard corresponds to the  
value 0.  
Hold down the button.  
-12  
0
+12  
C
Pressing the TRANSPOSE button again turns the TRANSPOSE function off.  
The TRANSPOSE function remembers the current setting as long as the power is on.  
Transpose is active when the LED indicator is on, and the notes are transposed according to the set transpose value.  
For example if the setting is ‘-3’ and the LED indicator for the TRANSPOSE button is on, the notes will be transposed  
3 half steps lower. When the LED indicator for the TRANSPOSE button is turned OFF, the transpose setting will  
automatically return to ‘0’ (no transposition) with one touch.  
When the value is set to ‘0’, the LED indicator will not turn on.  
The CN31 piano’s transpose setting defaults to ‘0’ each time the power is turned on.

8) PLAYING WITH CONCERT MAGIC  
The great German composer Johann Sebastian Bach once said "Playing the keyboard is simple. Just strike  
the right keys at the right time". Many pianists wish it were quite that straightforward. Fortunately, KAWAI have  
devised a method of playing the keyboard that is very simple, without even needing to strike the right keys.  
With CONCERT MAGIC, absolutely anyone can sit at the CN piano and make real music - even complete  
beginners who have never taken a piano lesson in their life. To enjoy performing with Concert Magic, simply  
select a favorite piece from the 88 pre-programmed songs and tap any key with a steady rhythm and tempo.  
Concert Magic will provide the correct melody and accompaniment notes, regardless of which keys are pressed.  
With Concert Magic anybody, young or old, can enjoy playing music from the moment they sit down at the CN  
piano.  
2
SELECTING A SONG  
The 88 Concert Magic songs are assigned to each of the 88 keys, and classified by song category into eight  
groups, such as Children's Songs, American Classics, Christmas Songs etc. Please refer to the separate

PERFORMING A SONG  
Step1  
Tap out the rhythm of the selected song on any one of the piano’s 88 black or white keys.  
Concert Magic songs will respond to changes in playing style. As the keys are tapped harder, the music will  
grow louder; if the keys are tapped more softly, the music will become quieter. Tapping faster will cause the  
music to speed up, while tapping slower will make the music slow down accordingly. Using Concert Magic, even  
inexperienced pianists can sound like they have been playing for years, simply by pressing one key with one  
finger.  
2
Concert Magic is a perfect method for small children to learn music, especially when developing a sense of  
rhythm. For older people who may believe it is too late to learn the piano, Concert Magic offers an enjoyable first  
step. With Concert Magic, the CN piano can be enjoyed by everyone in the family, even those who have never  
touched a musical instrument in their life.  
CONCERT MAGIC PART VOLUME BALANCE  
When used with Concert Magic, the BALANCE slider adjusts the volume balance of the melody part and the  
accompaniment.  
Step1  
Move the balance slider to the right or left to adjust the volume balance.

CONCERT MAGIC SONG ARRANGEMENT TYPES  
After playing with Concert Magic for a while, performers may feel that such playing is too easy and that there is  
very little to learn. While it is true that some of the songs are very easy to play, even for beginners, there are also  
some songs which will prove challenging, and require practice to play proficiently.  
Each of the 88 Concert Magic songs fall into one of three different arrangement types, depending on the skill  
level required to perform them.  
EASY BEAT  
These are the easiest songs to play. To perform them, simply tap out a constant steady beat on any key on the keyboard.  
Look at the following example, ‘Für Elise’. Press the key with a steady sixteenth note rhythm.

When performing fast songs with Concert Magic, it is sometimes easier to tap two different keys with two  
alternating fingers in order to play at greater speed.  
SKILLFUL  
These songs range in difficulty from moderately difficult to difficult. To perform them, tap out the rhythm of both the  
melody and the accompaniment notes on any key on the keyboard, such as ‘Waltz of the Flowers’ shown below.

4. RECORDER  
The RECORDER function records performances in a similar way to that of a tape recorder. However, the CN  
piano records songs as digital data, instead of audio data - storing the music inside the instrument. Because  
each song is stored digitally, it is possible to modify various aspects during playback, such as adjusting the  
tempo without changing the pitch, or selecting different sound types and effects settings. Once fully understood,  
the recorder function provides an easy to use tool for both practicing and playing the piano.  
1) RECORDING (REC BUTTON)  
The CN31 allows up to three different songs to be recorded, stored in memory, and played back at the touch of  
a button. Each song has two separate tracks called ‘Parts’ that can be recorded independently. This allows the  
left-hand part to be recorded first on one track, then the right-hand part to be recorded later on the other track,  
while listening to the first part.  
When recording or playing back a song, each part (track) can be re-recorded or played back freely. Attempting  
to re-record a part will automatically erase all previously recorded performance information for that part,  
therefore when recording parts separately, it is most important to select the correct part carefully, in order to  
prevent accidentally overwriting a previously recorded part.  
The REC button is used for recording.  
4
The SONG buttons and PART buttons correspond to the SOUND SELECT buttons.  
STEP1  
Press and hold the REC button, then select a SONG (1, 2 or 3) and PART number (1 or 2).

indicating the song and the part to be recorded.  
During this time, the SONG and PART to be recorded can be changed freely by pressing the desired  
SONG or PART button.  
If no PART is selected PART1 will be selected automatically.  
When the REC button is released, the LED indicators for the selected SONG and PART buttons will stop flashing  
and the LED indicator for the REC button will turn on. This is the Standby state for recording. Furthermore, the  
LED indicator for the SOUND SELECT button will also turn on, allowing the sound for recording to be changed.

2) TEMPERAMENT  
The CN piano offers immediate access to a variety of musical temperaments popular during the Renaissance  
and Baroque periods. It may prove interesting and educational to experiment with different temperaments, other  
than the modern ‘equal temperament’ standard this is dominant in music today.  
BRIEF EXPLANATION OF TEMPERAMENTS  
EQUAL TEMPERAMENT  
(PIANO ONLY)  
This is the default temperament. If a piano sound is selected the tuning is  
stretched like an acoustic piano (EQUAL TEMPERAMENT). If any other type  
of sound is selected the tuning will be EQUAL (FLAT). An explanation of  
EQUAL TEMPERAMENT and EQUAL TEMPERAMENT (FLAT) is provided  
later in this section.  
If a piano sound is used in a layer with any other sound, then both sounds will  
use the EQUAL TEMPERAMENT (stretched) tuning.  
MERSENNE PURE TEMPERAMENT  
(MAJOR)  
This temperament, which eliminates dissonances for thirds and fifths, is still  
popular for choral music because of its perfect harmony.  
Performers must be aware which key they are playing in when using this  
temperament.  
MERSENNE PURE TEMPERAMENT  
(MINOR)  
Any key modulation will result in dissonances. When playing music in a  
particular key, the key of the temperament must also be correctly matched.  
When playing in a major key select Pure (Major) and when playing in a minor  
key select Pure (minor).  
PYTHAGOREAN TEMPERAMENT  
MEANTONE TEMPERAMENT  
This temperament, which uses mathematical ratios to eliminate dissonance  
for fifths, is very limited for use with chords, but it produces very characteristic  
melodic lines.  
This temperament, which uses a mean between a major and minor whole  
tone to eliminate dissonance for thirds, was devised to eliminate the lack  
of consonances experienced with certain fifths for the Mersenne pure  
temperament. It produces chords that are more beautiful than those with the  
equal temperament.  
WERCKMEISTER III TEMPERAMENT  
KIRNBERGER III TEMPERAMENT  
These two temperaments are placed in between Meantone and Pythagorean.  
For music with few accidentals, this temperament produces the beautiful  
chords of the mean tone, but as accidentals increase, the temperament  
produces the characteristic melodies of the Pythagorean temperament. It  
is used primarily for classical music written in the Baroque era to revive the  
original characteristics.  
5
EQUAL TEMPERAMENT (FLAT)  
EQUAL TEMPERAMENT  
This is an ‘unstretched’ equal temperament that divides the scale into twelve  
equal semitones. This produces the same chordal intervals in all twelve keys,  
and has the advantage of limitless modulation of the key. However the tonality  
of each key becomes less characteristic and no chord is in pure consonance.  
This is the most popular piano temperament. The hearing ability of a human is  
uneven and is not as accurate with high frequency and low frequency as it is  
with the middle range. This temperament's tuning is stretched to compensate  
for this so the sound will be heard naturally to the ears. This ‘stretched’ equal  
temperament is a practical variation of the ‘unstretched’ equal temperament  
which was invented on a mathematical basis.  
Step1  
Hold down the TOUCH and TRANSPOSE buttons and press the PIANO 2 button.  
2
1
Hold down both buttons.  
The display will alternate between showing ‘tMP’ (Temperament) and a symbol to indicate which type of  
temperament is in use.

Page  
39  
Step2  
Use the VALUE buttons to change the type of temperament.  
Temperament  
Equal (Piano)  
Pure (Major)  
Pure (Minor)  
Equal (Flat)  
Pythagorean  
Meantone  
Equal  
Kirnberger III  
Werckmeister III  
When the power is turned off, the temperament will reset to the factory default ‘equal temperament (piano only)’  
type.  
If a piano sound is selected when using the factory default ‘equal temperament (piano only)’ type, the tuning is  
stretched like an acoustic piano (EQUAL TEMPERAMENT). If any other type of sound is selected, the tuning will  
be EQUAL (FLAT).  
After selecting the desired temperament, please read the following section on selecting a key signature for the  
temperament before continuing.  
KEY SIGNATURE OF TEMPERAMENT  
Limitless modulation of the key became available only after the invention of equal temperament. When using  
a temperament other than equal temperament, care must be taken to choose the key signature to play in. For  
example, if the song to be played is written in D major, ‘D’ would be chosen as the temperament key.  
Step1  
5
Press one of the 88 piano keys to select the key signature of the temperament.  
The note name of the key pressed will be shown in the display and chosen as the key of the temperament.  
Changing the key of the temperament will only change the ‘balance’ of the tuning, the pitch of the keyboard will remain  
unchanged. Use the TUNING or TRANSPOSE functions to change the pitch of the whole keyboard.  
The key of the temperament function will have no effect when equal temperament is selected.

MIDI OVERVIEW  
The term MIDI is an acronym for Musical Instrument Digital Interface, an international standard for  
connecting synthesizers, sequencers (MIDI recorders) and other electronic instruments so that they can  
exchange performance data.  
The CN31 is equipped with two MIDI jacks for exchanging data: MIDI IN and MIDI OUT. Each uses a  
special cable with a DIN connector.  
MIDI IN : For receiving note, program change and other data.  
MIDI OUT : For sending note, program change and other data.  
MIDI uses channels to exchange data back and forth between MIDI devices. There are receive (MIDI IN)  
and transmit (MIDI OUT) channels. Most musical instruments or devices with MIDI functions are equipped  
with both MIDI IN and OUT jacks and are capable of transmitting and receiving data via MIDI.  
The receive channels are used to receive data from another MIDI device and the transmit channels are  
used to transmit data to another MIDI device.  
Connection to an external sequencer  
When connected as shown in the illustration below, songs played on the CN31 can be recorded using  
a MIDI recorder, with preset sounds (such as piano, harpsichord and vibraphone, etc.) controlled by the  
CN31’s MULTITIMBRAL MODE function to create a multi-layer MIDI recording.

LINE OUT JACKS  
These jacks provide stereo output of the CN31 piano’s sound to amplifiers, tape recorders or similar equipment.  
The audio signal coming through the LINE IN jacks is also routed to these jacks. The CN31 piano’s sound is  
mixed with the LINE IN signals.  
6
The CN31 piano’s VOLUME slider controls the output level of its own sound without affecting the level of the  
LINE IN signal.  
LINE IN JACKS

3
These jacks are used to connect a pair of stereo outputs from other audio equipment or electronic instruments  
to the CN31 piano’s speakers. The audio signal coming through these jacks bypasses the CN31 piano’s volume  
control. To adjust the volume level, use the output control of the external device.  
MIDI JACKS  
These jacks are used to connect external MIDI devices with the CN piano. There are two terminals: MIDI IN and  
MIDI OUT.  
PEDAL JACK

Connect the pedal cord from the pedal board to this jack.  
HEADPHONE JACKS  
There are two headphone jacks located on the left underside of the piano.  
The piano's sound and any audio signal that is connected to the LINE IN jacks will be heard through the  
headphones.
