3 BRILLIANCE control
This stider controls the brilliance, or clarity, of the sound.
Shifting it to the left produces a rich, mellow sound; shifting
it to the right, a bright, clear sound. The center position
corresponds to the instrument’s norma! tone.
4 TRANSPOSE control
Shifting the slider to the right raises the piano’s key {(C > C#
>D-> Eb €E - F); shifting it to the left lowers the key
(C>B7>BP>A~>Ab>+G-> FF). You can therefore play
the music as written — in C major, for example — and have the
instrument transpose the output to a higher or lower key to
match your voice.

lM Advanced Features
1) MIDI Interface
1 Introduction
The letters MiDI stand for Musical Instrument Digital Interface, an international standard for connecting synthersizers, drum
machines, and other electronic musical instruments so that they can exchange performance data. The P2500/P1000 feature three
MIDI jacks — IN, OUT, and THRU — that aliow it to both send and receive these kinds of data.
Note: The sending and receiving instruments must be assigned the same channel number before they can communicate.
2 Typical Applications
2.1 Ensemble playing with another keyboard instrument

The
only
differences
is
that
the

to
give it
more
depth.
Note: !f you reverse the MIDI IN and MIDI OUT connections, you can play the piano from the synthesizer just as easily.
2.2. Drum Machines

The above ijlustration shows how an external synthesizer module may be connected to the P2500/P1000 so that you can play two
or more instruments at once.
3 MIDI Implementation
The MIDI interface on your Kawai Electronic Piano allows you to:
(1) Receive and transmit keyboard data.
(2) Receive and transmit soft and damper pedal data (ON/OFF).
(3) Receive and transmit program numbers — codes for changing tone colors.
(4) Set MIDI channel numbers for sending and receiving to any number between 1 and 16.
(5) Turn LOCAL CONTROL on and off — either from the keyboard or another instrument.
(6) Receive volume data from an external source. (The MULTI TIMBRE mode permits independent recognition of volume data
on each channel.)

4 Operation
Ta issue commands to the MIDI interface or use the tuning capability, you must first switch the piano to a special “programming”
mode,
4.1 Entering the programming mode
1) Press the CHORUS switch.
2} Holding down the CHORUS switch, press the first three tone selector switches (PIANO 1, PIANO 2, and PIANO 3}.

Press simultaneously. Hold down.
3) The LEDs next to the CHORUS and PIANO 17 switches should then start flashing to indicate that the piano is in the program-
ming mode. In this mode, striking the keyboard produces no output.
4.2. Leaving the programming mode
1} Press the CHORUS switch.
2) The flashing will stop, and you will return to the tone color in effect when you entered the programming mode.
4.3. Sending a program number (tone color code)
The P2500/P1000 can send commands to other MIDI equipment to force program changes.
1) Make sure that the digital piano is in the programming mode. The flashing LED next to the PIANO 1 switch indicates that the
interface is ready to transmit a program number.

a Procedure
1) Make sure that the digital piano is in the programming mode. (See p. 6.4.1 “Entering the programming mode”’.)
2) Press the PIANO 2 switch to set the LED next to the PIANO 2 switch flashing.
3) Press the highest black key to turn the function off, the highest white one to turn it on.
4} Leave the programming mode. (See p. 6.4.2 ‘Leaving the programming mode”’.}
Note: When the power is first applied or reapplied after a short break, MULTI TIMBRE is off.
& Example
If the current MID{ channel is 3, the upper half of the keyboard sends on channel 3 and the lower half sends on channel 4. If the
current channel is 16, the lower half sends on channel 1.
4.6 Turning LOCAL CONTROL on and off
LOCAL CONTROL refers to the connection between the internal sound source and the keyboard, It is normally on. Turning it
off disconnects the keyboard; the instrument sounds only when it receives keyboard data through the MIDI interface. The key-
board can still control other MIDI devices connected to the P2500/P1000’s MID! OUT.
& Procedure
1) Make sure that the piano is in the programming mdoe. (See p. 6.4.1 ‘Entering the programming mode”.)

5) Leave the programming mode. (See p. 6.4.2 ‘‘Leaving the programming mode’’.)
Note: Momentarily turning off the power restores the original pitch.
3) Temperaments
Your Kawai digital piano offers not only equal temperament (the modern standard), but also immediate access
to those popular during the Renaissance and Baroque period.
& Procedure
1) Make sure that the piano is in the programming mode.
(See p. 6.4.1 “Entering the programming mode”’.)
2) Press the E, PIANO 2 switch so that it flashes to indicate
that the piano is waiting for a temperament specification.
3) Press one of the seven white keys at the lower end of the
keyboard to select one of these corresponding tempera-
ments.
. Equal temperament without the tuning curve
. Mersenne pure temperament
. Pythagorean temperament
. Meantone temperament
. Werck meister Il temperament
. Kirnberger fil temperament
. Equal temperament with the tuning curve
IOoh wh —
4) Leave the programming mode. (See p. 6.4.2 ““Leaving the
programming mode”’.)
Note: When the power is first applied or reapplied after
a short break, the piano returns to the modern
standard, equal temperament with the tuning
curve (#7}.
Key set function is also available at this point. As you know,
limitless modulation of the key became available only after
the inventation of Equal Temperament. When we use a
temperament except Equal Temperament, we must carefully
choose the key signature to play in.
To select the key signature setting, simply press one of the
keys marked on the front panel. For example, if the tune
you are going to play is written in D major, press D key to
set the key.
Please note that this will only change the “balance” of the
tuning, and the pitch of the keyboard will remain unchanged.
Use the Transpose function to change the pitch of the whole
keyboard.

s Temperament Characteristics
@ Equal temperament
This, by far the most popular piano temperament, divides the
scale into twelve equal semitones and has the advantage of
producing the same chords for al! transpositions.
@ Mersenne pure temperament
This temperament, which eliminates consonances for thirds
and fifths, is still popular for choral music.
® Pythagorean temperament
This temperament, which uses mathematica! ratios to elimi-
nate consonances for fifths, has problems with chords, but
produces a very beautiful melodic line.
®@ Meantone temperament
This temperament, which uses a mean between a major and
minor whole tone to eliminate consonances for thirds, was
devised to eliminate the lack of consonance experienced
with certain fifths for the Mersenne pure temperament. It
produces chords that are more beautiful than those with the
equal temperament.
© Werckmeister Il temperament, Kirnberger Ml temperament
For key signature with few accidentals, this temperament
produces
the
beautiful
chords
of
the
mean
tone,
but,
as
the
accidentals increase, the tension increases, and the tempera-
ment produces the beautiful melodies of the Pythagorean
temperament. It is used primarily for classical music written
to take advantage of these characteristics.
