Special Features
Creating New Sounds
Page 21
By adjusting just two knobs you can add varying degrees of distortion, “sweet-
ness,” or other characteristics to a sound to change it subtly or drastically. Param-
eters that can be assigned to the knobs include effect, filter, envelope generator
and more. You can create new sounds in real time!
Arpeggio Function
Page 20
Similar to the arpeggio functions provided on some synthesizers, this function
automatically produces arpeggios (broken chords) when you simply play the
appropriate notes on the keyboard. A variety of arpeggios can be produced by
changing your fingering or the arpeggio type.
Play a Variety of Instrument Voices
Page 16
The instrument voice that sounds when you play the keyboard can be changed to
violin, flute, harp, or any of an extensive range of voices. You can change the
mood of a song written for piano, for example, by using violin to play it instead.
Experience a whole new world of musical variety.
Play Along with Styles
Page 22
Want to play with full accompaniment? Try the auto-accompaniment Styles.
The accompaniment styles provide the equivalent of a full backing band cover-
ing a wide variety of styles from waltzes to 8-beat to euro-trance ... and much
more. Select a style that matches the music you want to play, or experiment with
new styles to expand your musical horizons.
Try playing the Tabla/Tanpura feature!
Page 23
This special feature lets you play Indian phrase patterns via the Tabla and Tan-
pura sounds, as if you were using the Tabla machine and Tanpura machine. Let’s
enjoy the conventional Indian music via the panel buttons and Knobs.

PRECAUTIONS
PLEASE READ CAREFULLY BEFORE PROCEEDING
Please keep this manual in a safe and handy place for future reference.
WARNING
Always follow the basic precautions listed below to avoid the possibility of serious injury or even death from electrical
shock, short-circuiting, damages, fire or other hazards. These precautions include, but are not limited to, the
following:
• Do not place the power cord near heat sources such as heaters or radiators. Also,
do not excessively bend or otherwise damage the cord, or place heavy objects on
it.
• Only use the voltage specified as correct for the instrument. The required voltage
is printed on the name plate of the instrument.
• Use the specified adaptor (page 81) only. Using the wrong adaptor can result in
damage to the instrument or overheating.
• Check the electric plug periodically and remove any dirt or dust which may have
accumulated on it.
• This instrument contains no user-serviceable parts. Do not open the instrument
or attempt to disassemble or modify the internal components in any way. If it
should appear to be malfunctioning, discontinue use immediately and have it
inspected by qualified Yamaha service personnel.
• Do not expose the instrument to rain, use it near water or in damp or wet
conditions, place on it any containers (such as vases, bottles or glasses)
containing liquids which might spill into any openings. If any liquid such as
water seeps into the instrument, turn off the power immediately and unplug the
power cord from the AC outlet. Then have the instrument inspected by qualified
Yamaha service personnel.
• Never insert or remove an electric plug with wet hands.
• Do not put burning items, such as candles, on the unit. A burning item may fall
over and cause a fire.
• Follow the precautions below. Failure to do so might result in explosion, fire,
overheating or battery fluid leakage.
- Do not tamper with or disassemble batteries.
- Do not dispose of batteries in fire.
- Do not attempt to recharge batteries that are not designed to be charged.
- Keep the batteries separate from metallic objects such as necklaces, hairpins,
coins, and keys.
- Use the specified battery type (page 12) only.
- Use new batteries, all of which are the same type, same model, and made by
the same manufacturer.
- Always make sure all batteries are inserted in conformity with the +/- polarity
markings.
- When the batteries run out, or if the instrument is not to be used for a long
time, remove the batteries from the instrument.

CAUTION
Always follow the basic precautions listed below to avoid the possibility of physical injury to you or others, or damage
to the instrument or other property. These precautions include, but are not limited to, the following:
• Do not connect the instrument to an electrical outlet using a multiple-connector.
Doing so can result in lower sound quality, or possibly cause overheating in the
outlet.
• When removing the electric plug from the instrument or an outlet, always hold
the plug itself and not the cord. Pulling by the cord can damage it.
• Remove the electric plug from the outlet when the instrument is not to be used for
extended periods of time, or during electrical storms.
• Do not place the instrument in an unstable position where it might accidentally
fall over.
• Before moving the instrument, remove all connected cables, to prevent damage
to the cables or injury to anyone who might trip over them.
• When setting up the product, make sure that the AC outlet you are using is easily
accessible. If some trouble or malfunction occurs, immediately turn off the power

Power Requirements
Although the instrument will run either from an
optional AC adaptor or batteries, Yamaha recom-
mends use of an AC adaptor whenever possible. An
AC adaptor is more environmentally friendly than bat-
teries and does not deplete resources.
Using an AC Power Adaptor
1 Make sure that the power of the instrument is off
(display is blank, except for notation staff).
2 Connect the AC adaptor to the power supply jack.
3 Plug the AC adaptor into an AC outlet.
Using Batteries
This instrument requires six “AA” size, Alkaline
(LR6)/Manganese (R6) batteries, or rechargeable
nickel-metal hydride batteries (rechargeable Ni-MH
batteries). The Alkaline batteries or rechargeable Ni-
MH batteries are recommended for this instrument,
since other types may result in poorer battery perfor-
mance.
Installing the batteries
1 Make sure that the power of the instrument is off
(display is blank, except for notation staff).
2 Open the battery compartment cover located on the
instrument’s bottom panel.
3 Insert the six new batteries, being careful to follow
the polarity markings on the inside of the compart-
ment.
4 Replace the compartment cover, making sure that it
locks firmly in place.
When battery power becomes too low for proper oper-
ation, the volume may be reduced, the sound may be
distorted, and other problems may occur. When this
happens, make sure to replace all batteries with new
ones or already-recharged ones.
Setting the battery type
After installing the new batteries then turning the
power on, make sure to set the Battery Type to
Rechargeable type or not. For details, refer to page 50.
• Use the specified adaptor (page 81) only. Using the
wrong adaptor can result in damage to the instrument
or overheating.
• When setting up the product, make sure that the AC
outlet you are using is easily accessible. If some trou-
ble or malfunction occurs, immediately turn off the
power switch and disconnect the plug from the outlet.
Even when the power switch is turned off, electricity is
still flowing to the product at the minimum level. When
you are not using the product for a long time, make
sure to unplug the power cord from the wall AC outlet.
• When using Ni-MH batteries, follow the instructions that
came with the batteries. Use only the specified charger
device when charging.

Checking the power status on the
display
Power source on the display
You can confirm the power source at the left corner of
the display.
When is shown, the power is supplied from the
AC power adaptor. When is shown, the power is
supplied from the batteries. When the AC power adap-
tor is connected with the batteries installed, the power
is supplied from the AC power adaptor and the
indication is shown.
Remaining battery power indication
You can confirm the approximate amount of remain-
ing battery power at the top left of the display.
Connecting Headphones or
External Audio Equipment
Any pair of stereo headphones with a 1/4” stereo
phone plug can be plugged in here for convenient
monitoring. The speakers are automatically shut off
when a plug is inserted into this jack.
The PHONES/OUTPUT jack also functions as an
external output. You can connect the PHONES/OUT-
PUT jack to a keyboard amplifier, stereo system,
mixer, tape recorder, or other line-level audio device
to send the instrument’s output signal to that device.
Connecting a Footswitch to the
SUSTAIN jack
You can produce a natural sustain as you play by
pressing an optional footswitch plugged into the
[SUSTAIN] jack. Although the footswitch works as
the Sustain pedal for most Voices, it features other
functions such as Sostenuto and Arpeggio Hold (for
Voices 242–287). One of these functions can be
assigned to the footswitch on the Function display
(page 50).
Indicates that the power will be turned off
immediately. When rechargeable batteries are
used, this icon flashes before the power is
turned off.
Indicates that remaining power is insufficient
for operation. Before the power runs out,
replace all the batteries with new ones, or fully
recharged ones (when using rechargeable
types). Note that the instrument may not work
properly, including unusually soft volume and
poor sound quality when remaining power
becomes low.
Indicates that the remaining power is suffi-
cient.
Only one of these is shown.
Harmnum1
• Do not use the instrument/device or headphones for a long
period of time at a high or uncomfortable volume level,
since this can cause permanent hearing loss. If you experi-
ence any hearing loss or ringing in the ears, consult a phy-
sician.
• Before connecting the instrument to other electronic com-
ponents, set all volume levels to the minimum, then turn
off the power for all components.
• When the instrument’s sound is output to an external
device, first turn on the power to the instrument, then to
the external device. Reverse this order when you turn the
power off.
• When Split is on, the sustain function does not affect the cur-
rent Split Voice (page 17) while sostenuto and Arpeggio Hold
(page 39) affect only the current Split Voice.
• Make sure that the footswitch plug is properly connected to
the SUSTAIN jack before turning on the power.
• Do not press the footswitch while turning the power on. Doing
this changes the recognized polarity of the footswitch, result-
ing in reversed footswitch operation.

Quick Guide
Creating Arpeggios
The Arpeggio function lets you create arpeggios (broken chords) by simply pressing
the notes of the chord. For example, you could play the notes of a triad—the root, third,
and fifth—to trigger interesting phrases. This feature can be used for music production
as well as performance.
1
Press the [ARPEGGIO] button to turn on
the Arpeggio function.
2
Press a note or notes to trigger Arpeg-
gio.
The Arpeggio phrase differs depending on the
number of pressed notes and the area of the key-
board.
When Split is on, Arpeggio is applied only to the
Split Voice. When Split is off, Arpeggio is applied
to the Main and Dual Voices. Arpeggio cannot be
applied to the Split and Main/Dual Voices simulta-
neously.
3
To turn off the Arpeggio, press the
[ARPEGGIO] button again.
The most suitable Arpeggio Type is automatically
selected when you select a Main Voice, but you can
easily select any other Arpeggio Type.
1
Hold down the ARPEGGIO [TYPE] but-
ton for longer than a second.
In the display, “ARP Type” appears for a few sec-
onds, followed by the current Arpeggio Type
appears.
2
Rotate the dial to select the desired
Arpeggio type
For a list of the Arpeggio List, see page 77.
Triggering the Arpeggio
• Selecting a Voice number between 242 and 287 will turn
on Arpeggio automatically.
• When you select one of the Main Voices 272–281, Split
as well as Arpeggio is automatically turned on. This
allows you to immediately trigger an Arpeggio by press-
ing a key to the left of the Split Point after selecting one
of these Voices.
• When the Pedal Function is set to “Arp Hold” or
“Hold+Sus” (page 50), pressing the footswitch con-
nected to the SUSTAIN jack will cause Arpeggio play-
back continue even after the note is released.

Changing the Arpeggio Type
• When any of Voices 242–287 are selected, it is a good
idea to set the Pedal Function to “Arp Hold” or
“Hold+Sus” (page 50). This setting allows you to use a
footswitch (press and hold) to have Arpeggio playback
continue even after the note is released.
Hold for longer
than a second.
