Special Features
Creating New Sounds
Page 21
By adjusting just two knobs you can add varying degrees of distortion, “sweetness,” or other characteristics to a sound to change it subtly or drastically. Parameters 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.

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

Handling 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
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.
• Use only the stand specified for the instrument. When attaching the stand or rack,
use the provided screws only. Failure to do so could cause damage to the internal
components or result in the instrument falling over.
• Before connecting the instrument to other electronic components, turn off the
power for all components. Before turning the power on or off for all components,
set all volume levels to minimum.
• Be sure to set the volumes of all components at their minimum levels and
gradually raise the volume controls while playing the instrument to set the

instrument or other property, or operational failure.
• Do not rest your weight on, or place heavy objects on the instrument, and do not
use excessive force on the buttons, switches or connectors.
• 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 experience any hearing loss or ringing in the ears, consult a
physician.
Yamaha cannot be held responsible for damage caused by improper use or modifications to the instrument, or data that is lost or
destroyed.
Always turn the power off when the instrument is not in use.
Even when the [ ] (Standby/On) switch is in standby status (display is off), electricity is still flowing to the instrument at the minimum level.
When you are not using the instrument for a long time, make sure you unplug the power cord from the wall AC outlet.

Power Requirements
Although the instrument will run either from an
optional AC adaptor or batteries, Yamaha recommends use of an AC adaptor whenever possible. An
AC adaptor is more environmentally friendly than batteries 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).
• Use the specified adaptor (page 81) only. Using the
wrong adaptor can result in damage to the instrument
or overheating.
2 Connect the AC adaptor to the power supply jack.
3 Plug the AC adaptor into an AC outlet.
• 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 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.
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 compartment.
4 Replace the compartment cover, making sure that it
locks firmly in place.
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 NiMH batteries are recommended for this instrument,
since other types may result in poorer battery performance.
• When using Ni-MH batteries, follow the instructions that
came with the batteries. Use only the specified charger
device when charging.
PSR-I455 Owner’s Manual
12
• Connecting or disconnecting the power adaptor with batteries installed may turn the power off, resulting in loss of
data being recorded or transferred at the time.
When battery power becomes too low for proper operation, 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.
NOTE
• This instrument cannot charge the batteries. Use only the
specified charger device when charging.
• Power will be automatically drawn from the AC adaptor if an
AC adaptor is connected while batteries are installed in the
instrument.
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.
• Failure to set the Battery Type may shorten the amount of
the battery life. Make sure to set the Battery Type correctly.
Setting Up
Only one of these is shown.
CAUTION
NOTICE
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.
Harmnum1
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 adaptor 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 remaining battery power at the top left of the display.
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 sufficient.
Connecting Headphones or External Audio Equipment
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.
• 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 experience any hearing loss or ringing in the ears, consult a physician.
• Before connecting the instrument to other electronic components, 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.
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).
NOTE
• When Split is on, the sustain function does not affect the current 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, resulting in reversed footswitch operation.
Setting Up
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.
