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.

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.

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.

This section describes each of the parameters which can be assigned to the Knobs
(page 21).
z TABLA/TANPURA
Knob A adjusts the volume balance between the
sounds of Tabla 1 and 2, while Knob B adjusts the
volume balance between the sounds of Tabla and Tanpura.
x TABLA/TANPURA
Knob A adjusts the tempo of Tabla playback while the
Tanpura playback tempo is maintained. This follows
typical Indian music stylistic conventions. Knob B
raises or lowers the pitch of the Tabla/Tanpura sound
in semitones, with the exception of Tabla 1. This accurately simulates the characteristics of the Tabla, in
which the lower sound is not affected by the tuning.
Note that also the pitch of Tabla 2 may not be changed
depending on the Tabla/Tanpura pattern.
NOTE
• When Knob B is turned all the way left, only the pitch of the
Tabla 2 sound is raised abruptly by an octave. This is due to a
limitation in this instrument.
c FILTER
Filter effects shape the 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 synthesizerlike sounds.
NOTE
• These effects are applied only to the Main/Dual Voices played
on the keyboard.
• Filter effects can sometimes cause distortion in the bass frequencies.
Knob A: CUTOFF
Adjusts the filter’s cutoff frequency, and therefore the
brightness of the sound. Turning the Knob to the left
makes the sound more muffled or darker, while turning the Knob A to the right makes the sound brighter.
Knob B: RESONANCE
Adjusts the amount of Resonance applied at the filter’s cutoff frequency. Turning the Knob to the right
will increases the Resonance to emphasize the frequencies at the cutoff frequency, and thus “strengthens” the perceived effect of the filter.
v EFFECT
Knob A: REVERB
Reproduces the acoustic ambience of a concert hall or
club. Turning the Knob to the right will increase the
Reverb depth.
Knob B: CHORUS
Produces a layered “multi-instrument” effect. Turning
the Knob to the right will increase the Chorus depth.
NOTE
• These effects are applied only to the Main/Dual Voices played
on the keyboard.
b 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 best match the music you’re
playing.
Reference
Knob A: ATTACK
Adjusts the Attack Time (the amount of time it takes
the sound to reach maximum level when a key is
played). Turning the Knob to the right will increase
the Attack Time, thus slowing down the attack rate.

Knob B adjusts the volume balance between the sounds of the Tabla (assigned to
the [TABLA 1] and [TABLA 2] buttons) and Tanpura (assigned to the [TANPURA 1]–[TANPURA 4] buttons). Play with these Knobs as the patterns loop,
sing along if you wish, and create your own performance.
Knob A adjusts the tempo of Tabla/Tanpura playback. Setting to the minimum
left-most position results in half the default tempo, while setting to the maximum right-most position results in double the default tempo. The center position
corresponds to the default tempo. Note that the tempo cannot exceed the range
(11–280), and that the tempo of the Tanpura patterns will not change even if you
rotate Knob A. Knob B raises or lowers the pitch of the Tabla/Tanpura sound in
semitones. Regarding the Tabla, only the higher sound (assigned to the [2] button) will be transposed. Rotating the knob leftward lowers the pitch while rotating the knob rightward raises the pitch.
Use these knobs to set the desired tempo and key, sing along if you wish, and
create your own performance!
Select a synth-type lead or pad voice (see the Voice List; page 61). 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 67, Euro Trance. Turn accompaniment on and start style playback
(page 22). 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.

USB Flash Memory Operations
Precautions when using the [USB TO
DEVICE] terminal
This instrument features a built-in [USB TO
DEVICE] terminal. When connecting a USB
device to the terminal, be sure to handle the USB
device with care. Follow the important precautions
below.
Compatible USB devices
The instrument does not necessarily support all
commercially available USB devices. Yamaha cannot guarantee operation of USB devices that you
purchase. Before purchasing a USB device for use
with this instrument, check the following web
page:
http://download.yamaha.com/
Connecting USB flash memory
• When connecting a USB device to the [USB TO
DEVICE] terminal, make sure that the connector
on the device is appropriate and that it is connected in the proper direction.
• When connecting a USB cable, make sure that
the length is less than 3 meters.
• Though the instrument supports the USB 1.1
standard, you can connect and use a USB 2.0
storage device with the instrument. However,
note that the transfer speed is that of USB 1.1.
Using USB Flash Memory
By connecting the instrument to a USB flash memory, you can save data you’ve created to the connected device, as well as read data from the
connected device.
The number of USB flash memory to be used
Only one USB flash memory device can be connected to the [USB TO DEVICE] terminal.
Formatting USB flash memory
When a USB flash memory is connected, a message
may appear prompting you to format the device. If
so, execute the Format operation (page 53).
To protect your data (write-protect)
To prevent important data from being inadvertently
erased, apply the write-protect provided with the
particular USB flash memory. If you are saving
data to the USB flash memory, make sure to disable write-protect.
Connecting/removing USB storage device
Before removing the USB flash memory from the
[USB TO DEVICE] terminal, make sure that the
instrument is not accessing data (such as in the
Save and Delete operations).
• For more information about the handling of USB devices,
refer to the owner’s manual of the USB device.
• Other USB devices such as a computer keyboard or
mouse cannot be used.
• The format operation overwrites any previously existing
data. Make sure that the USB flash memory you are formatting does not contain important data.
• Avoid frequently connecting/disconnecting the USB
flash memory too often. Doing so may result in the
operation of the instrument “freezing” or hanging up.
While the instrument is accessing data (such as during
Save, Delete, Load and Format operations) or is mounting the USB storage device (shortly after the connection), do NOT unplug the USB flash memory, and do
NOT turn the power off. Doing so may corrupt the data
on either or both devices.
NOTICE
NOTICE
By connecting the USB flash memory device to the [USB TO DEVICE] terminal, you can
save the data created on this instrument, such as User Song and parameter settings.
The saved data can be recalled to this instrument again for the future use.
IMPORTANT
• It is recommended to use the Power Adaptor when executing USB flash memory operations, since battery power may
not be reliable enough to last through these crucial operations. When you try executing certain functions, the “Use
Adaptor” indication may appear and the selected function cannot be executed.

Troubleshooting
Appendix
When the instrument is turned on or off, a popping
sound is temporarily produced.
When using a mobile phone, noise is produced
The instrument is automatically turned off even if no
operation is done.
The volume is too soft.
The sound quality is poor.
The Style/Tabla/Song/Arpeggio stops unexpectedly or
will not play.
The recorded data of the song, etc. does not play correctly.
The LCD display suddenly goes dark, and all panel settings are reset.
No sound is produced even when the keyboard is
played, or a Song, Style, or Tabla/Tanpura is being
played back.
The footswitch (for sustain) seems to produce the opposite effect. For example, pressing the footswitch cuts off
the sound and releasing it sustains the sounds.
No sound is produced even when playing keys in the
right hand area of the keyboard, although chords played
in the left hand area are recognized.
Not all of the Voices seem to sound, or the sound seems
to be cut off, when playing the keyboard, Arpeggio, Style
or Tabla/Tanpura or Song.
The sound of the Voice changes from note to note.
The keyboard performance and playback of Style/Tabla/
Song produces an unexpected or inappropriate sound,
and cannot be restored to the normal status.
The Style, Tabla/Tanpura or Song does not start even
when the [START/STOP] button is pressed. The Arpeg-
Appendix
gio does not start even when the note is pressed with the
Arpeggio turned on.
The volume of the Style, Tabla/Tanpura or Song is too
low.
The chords played in the left hand area cannot be recognized even when the ACMP is turned on.
Style parts other than the Rhythm part produce no
sound.
The Styles numbered 194–206 produce no rhythm drum
sound even when the [START/STOP] button is pressed.
The ACMP indicator does not appear on the display
when the [ACMP ON/OFF] button is pressed.
ProblemPossible Cause and Solution
This is normal and indicates that the instrument is receiving electrical power.
Using a mobile phone in close proximity to the instrument may produce interference. To prevent this, turn off the mobile phone or use
it further away from the instrument
This is normal. This occurs due to the Auto Power Off function
(page 14).
The batteries are low or dead. Replace all six batteries with completely new ones or completely recharged ones, or use the AC
power adaptor.
Check whether a set of headphones or an audio cable is connected to the PHONES/OUTPUT, or not. When such a connection
is made, no sound is output from the speaker of this instrument.
Check the on/off status of the Local Control (page 49). Normally,
set this parameter to ON.
The polarity of the footswitch is reversed. Make sure that the footswitch plug is properly connected to the SUSTAIN jack before turning on the power.
Check whether or not the Dictionary function (page 45) is used.
When used, this is normal.
You have exceeded 32 simultaneous notes, which is the maximum
polyphony (the maximum amount of notes that can be played
simultaneously) of this instrument. If the Main, Dual, and Split
Voices are being used along with playback of Arpeggio, Style,
Tabla/Tanpura or Song, some notes/sounds may be omitted (or
“stolen”).
This is normal. The tone generation method uses multiple recordings (samples) of an instrument across the range of the keyboard;
thus, the actual sound of the Voice may be slightly different from
note to note.
Using the Knobs can produce dramatic changes in the sound, but
may also produce unexpected or undesired sounds. If you want to
restore the original, normal sound before being changed by the
Knobs, change the Voice, Style, Tabla/Tanpura or Song, or press
the [PORTABLE GRAND] button to reset the panel settings.
Check the on/off status of the External Clock (page 50). Normally,
set this parameter to OFF.
Check the volume setting in the Functions (pages 42 and 47).
Check the Split Point setting (page 43). Set this to the appropriate
value.
Check the on/off status of the ACMP (page 22). Make sure to turn
ACMP on.
This is normal. Style numbers 194–206 have no rhythm parts, so
no rhythm will play. When one of these Styles is selected, turn
ACMP on, then specify the chord in the left hand area to play Style
parts other than the Rhythm part.
Check the on/off status of the [STYLE] lamp. When using a Style,
press the [STYLE] button to turn on the [STYLE] lamp.

Voice List
Maximum Polyphony
The instrument has 32-note maximum polyphony. This means that it
can play a maximum of up to 32 notes at once, regardless of what
functions are used. Auto accompaniment uses a number of the available notes, so when auto accompaniment is used the total number of
available notes for playing on the keyboard is correspondingly
reduced. The same applies to the Split Voice and Song functions. If
the maximum polyphony is exceeded, earlier played notes will be cut
off and the most recent notes have priority (last note priority).
NOTE
• The Voice List includes MIDI program change numbers for each voice. Use
these program change numbers when playing the instrument via MIDI from
an external device.
• Program change numbers are often specified as numbers “0–127.” Since this
list uses a “1–128” numbering system, in such cases it is necessary to subtract 1 from the transmitted program change numbers to select the appropriate sound: e.g. to select No. 2 in the list, transmit program change number 1.
• Some voices may sound continuously or have a long decay after the notes
have been released while the sustain pedal (footswitch) is held.

• “ ” indicates that the drum sound is the same as “Standard Kit 1”.
• Each percussion voice uses one note.
• The MIDI Note is actually one or two octave(s) lower than keyboard Note (see Default Octave column). For example, in “222: Standard Kit 1”, the “Seq
Click H” (Note C1) corresponds to (Note C0: Note# 24).
• Key Off: Keys marked “O” stop sounding the instant they are released.
• Voices with the same Alternate Note Number (*1 ... 4) cannot be played simultaneously. (They are designed to be played alternately with each other.)
• Actual keyboard notes of 14 “Tabla” are one octave lower than the ones described in the list below. For example, the C4 sound in the following list is
actually played from C3.

Harmony types 01–05 are pitch-based and add one-, two- or three-note harmonies to the single-note
melody played in the right hand. These types sound when chords are played in the auto accompaniment range of the keyboard. These Harmony types will also work when playing songs that contain
chord data.

Types 6–26 are rhythm-based effects and add embellishments or delayed repeats in
time with the auto accompaniment. These types sound whether the auto accompaniment is on or not; however, the actual speed of the effect depends on the Tempo setting. The individual note values in each type let you synchronize the effect precisely to
the rhythm. Triplet settings are also available: 1/6 = quarter-note triplets, 1/12 = eighthnote triplets, 1/24 = sixteenth-note triplets.
• The Trill effect Types (06–12) create two-note trills (alternating notes) when two notes
are held.
• The Tremolo effect Types (13–19) repeat all held notes (up to four).
• The Echo effect Types (20–26) create delayed repeats of each note played.
