WELCOME TO THE MP4

Thank you for purchasing the KAWAI MP4. The MP4 Stage Piano features
64 Internal Sounds of the highest quality. The MP4 can also be used as a
MIDI master controller. On stage, at home, or in the studio, the MP4 has
been designed to offer quick and easy access to many sophisticated features.

BASIC FEATURES of the MP4

4 ASSIGNABLE ZONES

The MP4 keyboard can be divided into 4 zones. Each zone can be set to
INT, EXT or BOTH individually. INT (Internal) is to play any of the 64
internal sounds. EXT (External) is to play external MIDI devices. BOTH is
to play internal sounds and external MIDI devices at the same time. Each
zone can be played individually, or multiple zones can be freely split, layered
and velocity switched to create stunning and personalized performances.

ACOUSTIC TOUCH KEYBOARD

The MP4’s Advanced Hammer Action IV keyboard provides excellent feel
and control like that found in an acoustic piano.

64 INTERNAL SOUNDS, 64 SETUPS

The MP4 offers not only acoustic piano and electric piano sounds, but also
other sounds such as organ, brass, pads and so on. All the settings of these
sounds, together with the settings to control the external devices, can be
stored into 64 setups.

REVERB AND EFFECTS

The MP4 offers 7 high quality REVERB types, and 20 different EFFECT
types to improve acoustical realism and enhance tonal quality.

CONTROL KNOBS

The MP4 has 4 multi-function CONTROL KNOBS, which offer real time
control of the EFFECTS, EQ, TONE MODIFY and MIDI-CONTROL
CHANGE messages.

2. Basic Operations

2.1 Getting Ready

Since the MP4 has no built-in speakers, you will need to connect a mixer,
keyboard amplifier or headphones in order to listen.

Turn the MP4 on, using the POWER SWITCH on the rear panel.
It is recommended to turn the MP4 on before turning on any amplifiers in
order to avoid switching noise.

What you need to know before starting:

Please read this part for a better understanding of the MP4 structure.

Basically there is no difference between SOUND and SETUP mode. The
main difference is that SETUP is used to recall your stored SETUPs.
You can edit and make changes in both modes freely. The same parameters
are available in both modes.
If you edit in SOUND mode, your settings get lost, after power off, if you
don’t store them as SETUP!
If you want to start from scratch use the SOUND mode and press PIANO
ONLY first.
If you want to modify a SETUP just select it and start editing and store later
it as SETUP.

2.2 Selecting a Sound

If you notice when you select a sound that it sounds strange it’s probably
because some of the parameters like knobs etc. were edited. To get back to
the default settings for any sound simply use the PIANO ONLY function
and reselect the sound.

The MP4 always starts up in SOUND mode when the power is turned ON.
The SOUND button will be lit to indicate SOUND mode is active.

The Sounds are organized in 8 categories with 8 sounds each (total 64 sounds).
To select a sound press any of the SOUND SELECT buttons in the upper
row to choose a sound category.

Use any of the SOUND SELECT buttons in the lower row to select one of
the internal sounds out of the selected category.

The display shows the currently selected sound name.

1 Concert Grand

12

Note:

Internal sounds or Setups can be also selected using the VALUE buttons.

You should also listen to the preprogrammed Setups.
Setups are organized in 8 Banks with 8 Numbers each (total 64 Setups).
Press the SETUP button to change to SETUP mode and select a Setup by
pressing one of the Bank buttons in the upper row followed by a Number
button in the lower row.
The display shows the currently selected Setup name.

In Sound mode, the “1” in the display indicates that the zone 1 is currently
selected. The default settings of the zones are as follows.

Zone 1 Internal On (Plays internal sound)
Zone 2 Internal Off (Muted)
Zone 3 External On (Plays external device) The default TX channel is 1.
Zone 4 External Off (Muted)

The zone mode for each zone is indicated by the INT/EXT LED beside the
faders. The zone status for each zone is indicated by the ZONE ON/OFF
buttons. If the ZONE buttons is red, this zone is assigned to the entire
keyrange of the MP4. If the button is green, the key range for that zone is
less than the entire key range. You can check the key range setting by holding
the SELECT button for the zone for 1 second.

2.3 Layer

2.4 Split

Let’s try layering another sound. Turn the zone 2 on by pressing the ZONE
ON/OFF button for zone 2. The ZONE SELECT button for zone 2 is
automatically selected and the display shows the sound name for zone 2.

Select the sound for zone 2 with the SOUND SELECT buttons as shown in
the previous section.

2 String Pad

Adjust the volume balance of zone 1 and 2 with the faders for each zone.

Now let’s split the keyboard and play different sounds in upper and lower
sections.

Press and hold the ZONE SELECT button for zone 1. The display shows
the key range for zone 1 as follows.

1Key IC-2 >G8

RangeEC-2 >G8

While still holding down the ZONE SELECT button for zone 1, press the
lowest note on the keyboard. The display changes as follows.

1KeyRange(Both)

=IA-1 > ----

13

While still holding down the ZONE SELECT button for zone 1, select the
highest note for zone 1, for example, B2 by pressing B2 key on the keyboard.

1KeyRange(Both)

=IA-1 > B2

Repeat the same procedure for zone 2 while holding down the ZONE
SELECT button for zone 2 and set the key range from C3 to C7.

2KeyRange(Both)

=IC3 > C7

Now the keyboard is split as follows.

2.5 Piano Only

2.6 Metronome

ZONE 1

B2 C3

Note:
In this method, the key ranges for internal and external zones always
change together. If you want individual settings, use the Key Range Hi/
Lo parameter in MENU (see page 31).

The Piano Only function lets you quickly return the MP4 sounds to the default
settings.

Press the PIANO button and the SOUND SELECT button 1 simultaneously.
All the current settings (except for SYSTEM settings) will go back to original
and only Concert Grand sound can be played on the whole keyboard.

Note:

You may use this function also as a kind of Panic or Reset button. Also it is
a good starting point to create Setups from scratch.

A metronome is available on the MP4.

ZONE 2

Press the STORE and SYSTEM buttons simulataneously to start the
metronome.

Press the STORE or SYSTEM button to stop the metronome.

Changing the Tempo/Volume

The display will show as follows.

METRONOME
VOL= 5 =120

Use the VALUE buttons to change the tempo.

14

2.7 Transpose

Use the MENU buttons to change the volume.

Note:
The metronome tempo is also used as MIDI clock tempo to control an
external sequencer. See page 20 for details.

When the Transpose function is “ON” the MP4’s key can be raised or lowered
in half steps. The available range of transposition is 24 semitones, either up
or down.

While holding down the TRANSPOSE button, press any key on the MP4
keyboard to select a new transposed key. Pressing the F key above middle C
for example will transpose the MP4 UP to the key of F (+5 half steps).

The transpose amount can also be set using the VALUE buttons.
While holding the TRANSPOSE button down, press the VALUE buttons to
change the transpose amount.
The display shows the current TRANSPOSE amount when the TRANSPOSE
button is held down. A value of “0” indicates no transposition.

2.8 Using the MP4 as a MIDI controller

The MP4 can control external devices via MIDI.

MIDI Connection

Connect the MIDI OUT on the MP4 to the MIDI IN on an external MIDI
device with a MIDI cable.

Selecting the MIDI Channel

The MIDI Transmit Channel of the MP4 must be matched with the Receive
Channel of any MIDI devices connected to the MP4.

Select zone 3 by pressing the ZONE SELECT button 3. (Zone 3 is set to
external as default setting.)

Press the MENU-UP button until “TX Channel” (Transmit Channel) appears
on the display.

3External
TX Channel = 1

Use the VALUE buttons to choose a MIDI Transmit Channel from 1 to 16.

15

To exit from MENU, press both MENU UP and DOWN buttons
simultaneously.

Any notes played on the keyboard or any movements of the Knobs, sliders,
etc. will be transmitted to any external MIDI devices connected to the MIDI
out of the MP4 on the selected MIDI channel.

Sending Program Change Number

The MP4 can send MIDI program change numbers from 1 to 64 in SOUND
mode. Simply press the SOUND SELECT buttons and the corresponding
program number will be transmitted. See the program number table below.

page 31 for details.

The MP4 offers 64 preset combinations of the panel settings called SETUPs.
To select a SETUP, press the SETUP button. Now the SOUND SELECT
buttons are used to select a SETUP. Use a combination of the numbers in
the upper row and bottom row to select a desired SETUP. The display will
show the selected SETUP name.
