PRECAUTIONS
PLEASE READ CAREFULLY BEFORE PROCEEDING
* Please keep this manual in a safe 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:
Power supply/AC power adaptor
• 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 (PA-3C, or an equivalent recommended by Yamaha)
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.
• Do not place the AC adaptor cord near heat sources such as heaters or radiators,
and do not excessively bend or otherwise damage the cord, place heavy objects
on it, or place it in a position where anyone could walk on, trip over, or roll
anything over it.
Do not open
• Do not open the instrument or attempt to disassemble the internal parts or
modify them in any way. The instrument contains no user-serviceable parts. If it
should appear to be malfunctioning, discontinue use immediately and have it
inspected by qualified Yamaha service personnel.
Water warning
• Do not expose the instrument to rain, use it near water or in damp or wet
conditions, or place containers on it 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.
Fire warning
• Do not put burning items, such as candles, on the unit.
A burning item may fall over and cause a fire.
If you notice any abnormality
• If the AC adaptor cord or plug becomes frayed or damaged, or if there is a
sudden loss of sound during use of the instrument, or if any unusual smells or
smoke should appear to be caused by it, immediately turn off the power switch,
disconnect the adaptor plug from the outlet, and have the instrument inspected
by qualified Yamaha service personnel.
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:
Power supply/AC power adaptor
• When removing the electric plug from the instrument or an outlet, always hold
the plug itself and not the cord.
• Unplug the AC power adaptor when not using the instrument, or during
electrical storms.
• 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.
Battery
• Always make sure all batteries are inserted in conformity with the +/- polarity
markings. Failure to do so might result in overheating, fire, or battery fluid
leakage.
• Always replace all batteries at the same time. Do not use new batteries together
with old ones. Also, do not mix battery types, such as alkaline batteries with
manganese batteries, or batteries from different makers, or different types of
batteries from the same maker, since this can cause overheating, fire, or battery
fluid leakage.
• Do not dispose of batteries in fire.
• Do not attempt to recharge batteries that are not intended to be charged.
• When the batteries run out, or if the instrument is not to be used for a long time,
remove the batteries from the instrument to prevent possible leakage of the
battery fluid.
• Keep batteries away from children.
• If the batteries do leak, avoid contact with the leaked fluid. If the battery fluid
should come in contact with your eyes, mouth, or skin, wash immediately with
water and consult a doctor. Battery fluid is corrosive and may possibly cause
loss of sight or chemical burns.
Location
• Do not expose the instrument to excessive dust or vibrations, or extreme cold or
heat (such as in direct sunlight, near a heater, or in a car during the day) to
prevent the possibility of panel disfiguration or damage to the internal
components.
• Do not use the instrument in the vicinity of a TV, radio, stereo equipment, mobile
phone, or other electric devices. Otherwise, the instrument, TV, or radio may
generate noise.
• Do not place the instrument in an unstable position where it might accidentally
fall over.
(4)-12 1/2
4 PSR-I425 Owner’s Manual
• Before moving the instrument, remove all connected adaptor and other cables.
• 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

power for all components. Before turning the power on or off for all
components, set all volume levels to minimum. Also, 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 desired listening level.
Maintenance
• When cleaning the instrument, use a soft, dry cloth. Do not use paint thinners,
solvents, cleaning fluids, or chemical-impregnated wiping cloths.
Handling caution
• Do not insert a finger or hand in any gaps on the instrument.
• Never insert or drop paper, metallic, or other objects into the gaps on the panel
or keyboard. If this happens, turn off the power immediately and unplug the
power cord from the AC outlet. Then have the instrument inspected by qualified
Yamaha service personnel.
• Do not place vinyl, plastic or rubber objects on the instrument, since this might
discolor the panel or keyboard.
• 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.

Special Features of the PSR-I425
■ Creating New Sounds Page 18
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 14
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.
■ Performance assistant technology Page 23
Play along with a song on the instrument’s keyboard and produce a perfect
performance every time ... even if you play wrong notes! All you have to do
is play on the keyboard—alternately on the left- and right-hand ranges of the
keyboard, for example—and you’ll sound like a pro as long as you play in
time with the music.
■ Play a Variety of Instrument Voices Page 28
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 33
Want to play with full accompaniment? Try the auto-accompaniment Styles.
The accompaniment styles provide the equivalent of a full backing band covering 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.

Setting Up
• Use only manganese or alkaline batteries for this instrument.
Other types of batteries (including rechargeable batteries) may
exhibit a sudden drop in power when the batteries are low, possibly resulting in a loss of flash memory data.
• Be sure to install the batteries in the same direction, maintaining
the correct polarity (as shown). Incorrect battery installation may
result in heat, fire and/or leaking of corrosive chemicals.
• When the batteries run down, replace them with a complete set of
six new batteries. NEVER mix old and new batteries. Do not use
different kinds of batteries (e.g. alkaline and manganese) at the
same time.
• If the instrument will not be used for an extended period of time,
remove the batteries to prevent possible fluid leakage.
• Please use the power adaptor when transferring data to flash
memory. Batteries (including rechargeable types) can be drained
rapidly by this type of operation. If the batteries do become
drained during a data transfer, both the data being transferred and
the data currently in the transfer destination will be lost.
Be sure to do the following operations BEFORE turning on the power.
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
Make sure that the [STANDBY/ON] switch of the
instrument is set to STANDBY.
WARNING
• Use the specified adaptor (PA-3C, or an equivalent recommended by Yamaha) only. The use of other adaptors may
result in irreparable damage to both the adaptor and the
instrument.
Connect the AC power adaptor to the power supply
jack.
Plug the AC adaptor into an AC outlet.
CAUTION
• Unplug the AC Power Adaptor when not using the instrument,
or during electrical storms.
Adaptor
AC outlet
■ Using Batteries
Open the battery compartment cover located on the
instrument’s bottom panel.
Insert the six new batteries, being careful to follow
the polarity markings on the inside of the compartment.
Replace the compartment cover, making sure that it
locks firmly in place.
NOTE
• Connecting the AC power adaptor automatically supplies power from
the adaptor and overrides battery power, even when batteries are
installed.
10 PSR-I425 Owner’s Manual
For battery operation the instrument requires six 1.5V
“D” size, R20P (LR20) or equivalent batteries. (Alkaline
batteries are recommended.) When battery power
becomes too low for proper operation, make sure to
replace all batteries, following the precautions listed
below.
If necessary, also make sure to save all important User
data (see page 56), since custom panel settings are
lost when the batteries are removed.
CAUTION
Make all necessary connections below BEFORE turning the power on.
• Even when the switch is in the “STANDBY” position, 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
AC power adaptor from the wall AC outlet, and/or remove the batteries from the instrument.
•Never attempt to turn the power off when a “WRITING!” message
is shown in the display. Doing so can damage the flash memory
and result in data loss.
Setting Up
Connecting Headphones (PHONES/OUTPUT Jack)
The PSR-I425 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/OUTPUT
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.
WARNING
•Avoid listening with the headphones at high volume for long periods of time; doing so may not only result in ear fatigue, it may be
damaging to your hearing.
CAUTION
•To prevent damage to the speakers, set the volume of the external
devices at the minimum setting before connecting them. Failure to
observe these cautions may result in electric shock or equipment
damage. Also, be sure to set the volumes of all devices at their
minimum levels and gradually raise the volume controls while
playing the instrument to set the desired listening level.
Connecting to a Computer (USB Terminal)
Connect the instrument’s USB terminal to the USB terminal of a computer, and you can transfer performance
data and song files between the two (page 86). To use
the USB data-transfer features you’ll need to do the following:
• First, make sure the POWER switch on the instrument is set to OFF, then use a USB cable to connect the instrument to the computer. After making
the connections, turn on the power of the instrument.
• Install the USB MIDI driver on your computer.
Installation of the USB MIDI driver is described on
page 94.
NOTE
• Make sure to purchase a quality USB cable at a musical instrument
store, computer store or electrical appliance store.
Connecting a Footswitch (SUSTAIN Jack)
The sustain function lets you produce a natural sustain
as you play by pressing a footswitch. Plug the Yamaha
FC4 or FC5 footswitch into this jack and use it to switch
sustain on and off.
NOTE
• 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.
Turning the Power On
Turn down the volume by turning the [MASTER VOLUME] control to the left and press the [STANDBY/ON]
switch to turn on the power. Press the [STANDBY/ON]
switch again to turn the power OFF.
Backup data in the flash memory is loaded to the instrument when the power is turned on. If no backup data
exists on flash memory, all instrument settings are
restored to the initial factory defaults when the power is
turned on.

Creating Arpeggios
Quick Guide
The arpeggio function lets you create arpeggios (broken chords) by
simply playing the required notes on the keyboard. For example, you
could play the notes of a triad—the root, third, and fifth—and the arpeggio function will automatically create a variety of interesting arpeggiotype phrases. By changing the arpeggio type and the notes you play it
is possible to create a wide range of patterns and phrases that can be
used for music production as well as performance.
Press the [ARPEGGIO ON/OFF] button to turn the arpeggio function on.

You can play a style and specify the style chords with your left hand while playing arpeggios with your
right hand to create interesting sonic textures and backgrounds.

For this example we’ll use a grand piano voice, so press the [PORTABLE GRAND]
button. This convenient voice selection method lets you instantly select a voice with a
single button press.
2 After turning the arpeggio function on, select an arpeggio type (steps 1
and 2 on the preceding page).
For this example select “02 DownOct1”.
That completes preparation to use the arpeggio function.
3 Select the style you want to play along with the arpeggio function.
A “style” is an automatic accompaniment pattern.
Press the [STYLE] button and the name of the currently selected style will appear in the
display. Rotate the dial to select the desired style. For this example we’ll use the “001

The accompaniment will change accordingly each time you play a new left-hand chord.
Of course you can also change your right-hand fingering to produce interesting changes.
If you’re not comfortable with right-hand playing yet, you could use the performance
assistant technology feature described on page 23. When the performance assistant feature
is on, playing any right-hand key will always produce musically appropriate notes!
Split point
Whenever you’re playing a style as well as a right-hand part, be sure that your left hand
plays only to the left of the split point and your right hand plays only to the right of the
split point. (page 30)

Create Original Sounds
The two knobs located in the lower left area of the panel can be used to
add variations to the sound being played, transforming the sound in a
variety of musical ways. Filter, envelope generator, and other effects
can be assigned to the two knobs as required. In this section we’ll
explain how effects can be assigned to the knobs, and provide a few
tips for their use.

z Filter
Filter effects shape sound by allowing only a specified range of frequencies
to pass and/or by producing a resonance peak at the filter’s “cutoff” frequency. Filter effects can be used to create a range of synthesizer-like
sounds.
* Filter effects can sometimes cause distortion in the bass frequencies.
Some hints for using the filter effects are provided on page 22.

Knob A adjusts the filter’s cutoff frequency, and therefore the brightness of

c EG (Envelope Generator)
Envelope Generator effects determine how the level of the sound varies over
time. You can make the attack faster for a more percussive sound or slower
for a violin-like sound, for example. Or you can lengthen or shorten the sustain to most ideally match the music.
Knob A adjusts attack time (the amount of time it takes the sound to reach
maximum level when a key is played).
Knob B adjusts release time (the amount of time it takes for the sound to
decay to silence after a key is released).

If you select a different keyboard voice the knobs will be reset and the
ideal settings for the selected voice will be automatically recalled. In the
same way, if the “v STYLE FILTER” effect is selected, the knobs will
be reset if a different style is selected. If you create an original setting
you like, it might be a good idea to save it in the instrument’s Registration Memory (page 80) so you can recall the same settings again at any
time. You can also record performances using original sounds you’ve
created (page 52).
The chart below lists some interesting ways to use the various effects
that can be assigned to the knobs.
Changing the knob settings does not immediately change the sound. Newly
assigned effects will only change the sound when the knobs are first
operated after the new effect has been selected.

Select a synth-type lead or pad voice (page 107). Turn Knob B all the way up and operate Knob A
while playing for some spacey, floating 1980’s effects.
Select a voice that sounds as though it already has reverb and chorus effects applied, and turn
Knob A and Knob B all the way down to hear the “direct” sound of the voice. You can then turn the
Knob A and Knob B settings up to add extra impact and richness to the voice.
Select a piano voice, and turn Knob B all the way up and Knob A to about the 3 o’clock position.
This should give you a majestic, organ-like sound. The attack time is quite long so play the keys
and hold them to let the sound come in fully. Ideal for slow pieces.
Select style 31, Euro Trance. Turn accompaniment on and start style playback (page 34). Set
Knob B to about 3 o’clock, and Knob A to about 8 o’clock. The overall sound of the style should be
a bit muffled, with the drums emphasized for solid rhythmic impact.
