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 53) 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.

• When one of the following problems occur, immediately turn off the power switch and

disconnect the electric plug from the outlet. Then have the device inspected by Yamaha service

personnel.

- The power cord or plug becomes frayed or damaged.

- It emits unusual smells or smoke.

- Some object has been dropped into the instrument.

- There is a sudden loss of sound during use of 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 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 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 desired listening level.

• 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.

This could cause physical injury to you or others, damage to 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.

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.

P-255 Owner’s Manual

Main Features

Exquisite sound of a concert grand piano faithfully reproduced by the Pure CF Sound Engine

In order to give the P-255 the best possible piano sound, we started by selecting the one Yamaha

concert grand piano with the highest quality tone and acoustic properties. Expert tuners then pains-

takingly ensured that the selected piano was perfectly pitched, and finally, our Pure CF Sound

Engine technology was employed to meticulously sample the full lifespan of every single note.

Graded Hammer keyboard with synthetic ivory keytops for an authentic feel

Developed with the aim of reproducing the sensation of playing a real grand piano, the Graded

Hammer (GH) keyboard features naturally weighted keys, with those in the low range feeling

heavier than those in the high range. As a result, the keyboard feels perfectly balanced over its

complete length. What’s more, the synthetic ivory finish applied to the white keys has excellent

moisture absorption characteristics, meaning that you can play in comfort for as long as you want

without fear of the keys becoming slippery.

Ten different rhythm tracks built in

Playing the keyboard along with one of the ten basic rhythm tracks built into your P-255 is a great

way to add spice to your performances, and as such, these automatic rhythms make playing more

fun. Featuring a range of different patterns from jazz, popular music, and the like, the digital

piano’s rhythm tracks are sure to include what you are looking for.

Live Music Toolbox for performing on-stage

Collectively known as the Live Music Toolbox, the P-255 features a number of functions that

come in handy when performing on stage. For example, you can use Sound Boost to make the

instrument sound louder and enhance its presence (page 18), and the Panel Lock function deacti-

vates buttons on the control panel so you won’t have to worry about pressing them by mistake

while playing (page 18). Meanwhile, you can also turn off the built-in speakers when alternatives

are provided on-stage (page 44). With these tools at your disposal, it is easier to set up your digital

piano on-stage and performing becomes much more enjoyable.

Operate the instrument using P-255 Controller on your iPad, iPhone, or iPod

With the specially developed app P-255 Controller running on your iPad, iPhone, or iPod, you can

remotely control your digital piano for even more convenience and flexibility. By presenting vari-

ous parameters on-screen, this app allows you to make settings in a visual, more intuitive manner.

Setting Up

Plug the appliance end of the AC power cord into

the bundled power adaptor as shown in the figure.

Plug the power adaptor’s DC cable into the [DC IN]

jack on the rear panel.

Plug the power adaptor’s AC power cord into a

domestic-use, AC wall socket.

Press the [ ] Standby/On switch.

The digital piano will turn on and the display at

the center of the control panel will light up.

To turn off the instrument, press the [ ] Standby/

On switch once again.

The Auto Power-Off function automatically turns off

your digital piano after a set period of inactivity in order

to save power. By default, it will turn off the instrument

after 30 minutes if it is not operated in any way.

Disabling the Auto Power-Off function

To disable the Auto Power-Off function, either set the

corresponding Function parameter to “Off” or turn on

the instrument while holding down the left-most key

on the keyboard. When disabled in this way, the

instrument will not turn off automatically.

Changing the Auto Power-Off time

Press the [FUNCTION] button to access the Func-

tion parameters.

Press the [FUNCTION] button repeatedly until Func-

tion parameter

F8.8

is shown. Then, press the [-/NO]

or [+/YES] button to select that Function parameter.

Set the desired Auto Power-Off time using the [-/NO]

and [+/YES] buttons.

• Available settings: OFF, 5, 10, 15, 30, 60, and 120 minutes

• Default setting: 30 minutes

Press the [FUNCTION] button to return to the previ-

ous screen.

Turning on the instrument

• Be sure to use only the correct power adaptor (page

53). Other adaptors may damage the instrument, cause

it to overheat, or create a fire hazard.

• Be sure to use a power supply at the correct voltage.

• Be sure to unplug the power adaptor from the AC wall

socket during electrical storms or if the instrument is

not to be used for an extended period of time.

• The digital piano remains charged and draws a small

amount of power even when turned off. Be sure, therefore,

to unplug the power adaptor from the AC wall socket if it

is not to be used for an extended period of time.

• Carry out the above procedure in reverse when disconnecting the power adaptor.

If you are going to use your instrument in a live

music situation such as on-stage, please read

the section Performing Live (page 36).

NOTE

Auto Power-Off

• Before the Auto Power-Off function turns off the instrument, unsaved data

will be automatically backed up. See page 46 for details of the data backed

up at this time.

• In certain modes of operation, the Auto Power-Off func-

tion will not turn off the digital piano when the set time

has elapsed. We recommend, therefore, that you

always turn off the instrument manually when you are

finished using it.

• If your digital piano is connected to other equipment

such as amplifiers, speakers, or a computer but you do

not intend to use it for some time, we recommend that

you turn off all devices as described in their owner’s

manuals. Doing so eliminates the risk of damage to the

other equipment. If you do not want the instrument to

turn off automatically when connected to other equip-

ment, disable the Auto Power-Off function.

If you are going to use your instrument in a live music

situation such as on-stage, we recommend that you

disable the Auto Power-Off function. (See page 37, 39.)

To adjust the volume, use the [MASTER VOLUME]

slider at the left of the control panel while playing the

keyboard to check the setting.

To set up the music rest, insert it into the groove at the

back of the control panel.

Your digital piano features two [PHONES] jacks,

allowing two sets of headphones to be connected at

the same time. If you wish to connect only one set,

either of the jacks can be used. No sound will be out-

put from the instrument’s speakers when headphones

are connected to either or both of the jacks.

When plugged into the [SUSTAIN PEDAL] jack, the

FC4 Foot Switch that came with your digital piano

functions in the same way as the damper pedal of an

acoustic piano—that is, it allows notes played while it

is operated to sustain for longer than normal after you

release the corresponding keys. You can also connect

either an FC3 Foot Pedal or an FC5 Foot Switch (sold

separately). The FC3 supports half-damper playing.

Half-damper playing

Your digital piano can adjust the length of sustain in

response to how much the pedal is operated. In spe-

cific terms, the more the pedal is operated, the longer

the notes sustain. If, for example, too much sustain is

applied when you operate the pedal, reduce the level

(and make the sound clearer) by allowing the pedal to

return slightly.

NOTE

Setting Up

P-255 Owner’s Manual

An LP-255 Pedal Unit (sold separately) can be con-

nected if you wish to play the digital piano using a full

set of three pedals. In such a case, please set up the

instrument and pedal unit on an L-255 Keyboard

Stand (sold separately).

Damper pedal

Located at the right of the pedal unit, the damper

pedal allows notes played while it is operated to sus-

tain for longer than normal after you release the corre-

sponding keys. This pedal supports half-damper

playing—the more you operate it, the longer the notes

sustain.

Damper-pedal resonance

Yo ur digital piano’s damper resonance function recreates the

effect of resonance between individual piano strings when

the damper pedal is operated. The depth of this resonance

can be set using the corresponding Function parameter

(page 40).

Sostenuto pedal

The pedal located at the middle of the pedal unit is

known as the sostenuto pedal. If you play a note or

chord on the keyboard and operate this pedal before

releasing the keys, the corresponding notes will sus-

tain until you allow the pedal to return. Notes played

while the pedal is operated are not affected, meaning

that you can play a staccato melody over a sustained

chord.

Soft pedal

Located at the left of the pedal unit, the soft pedal

slightly lowers the volume and softens the timbre of

notes played while it is being operated. This effect

lasts until the pedal is released. Because the soft pedal

has no effect on notes already playing, you should

operate it just before playing the notes to be softened.

Using pedals for Play and Stop operations

Yo u can configure either the center or left pedal to operate in

the same way as the control panel’s [PLAY/STOP] button

using the corresponding Function parameter (page 40).

Using an optional pedal unit

• Be sure to turn off the digital piano before connecting or disconnecting a pedal

unit.

Main Operations

Selecting & Playing Voices

P-255 Owner’s Manual

Using Dual mode as described below, you can layer

two Voices on the keyboard and play them together.

By combining Voices of different types in this way,

you can create a composite Voice of greater richness

and texture.

Select the two Voices you wish to layer

using the corresponding Voice buttons.

Your digital piano will get the selected Voices

ready for playing.

For details on selecting voices, see page 13.

Activate Dual mode.

Press the Voice buttons for the two selected Voices

together and verify that they both light up.

Voice 1 and Voice 2

Of the two Voices selected for layering, the one

selected using the Voice button closer to the left

will be designated Voice 1; the other, Voice 2.

When you activate Dual mode, the Voices’ octave

settings and volume balance in addition to their

reverb and effect types and depths will be auto-

matically optimized. If necessary, however, you

can change these settings using the corresponding

Playing Songs

Your digital piano can play built-in Preset Songs, User Songs that you have recorded, and commercially available

songs. These songs can be in one of two different formats—MIDI or audio.

Song Category list

*: Shown only when a USB flash drive has been plugged into the instrument.

**: Shown

only when the USB flash drive contains data of the corresponding format.

User Songs and Import Songs

The term User Song is used to refer to songs recorded using

the instrument itself; those created in any other way are

referred to as Import Songs. Songs contained within a folder

named USER FILES on a USB flash drive are designated as

User Songs and handled in the same way. Songs located

outside this folder are handled as Import Songs. If the USB

flash drive plugged into the instrument contains no USER

FILES folder, one will be created automatically when you

record a song to that drive. The recorded User Song will

then be saved in that folder.

Supported song data formats

Standard MIDI File formats 0 and 1

Standard MIDI File (SMF) formats are the most commonly

used MIDI formats for storing sequence data. SMF format 0

is used for MIDI songs recorded using this instrument.

Waveform Audio File format

Identified by a .wav file extension, Waveform Audio File For-

mat (WAV) is one of the most common formats used by

computers to record audio data. Your digital piano supports

the playback and recording of 44.1-kHz, 16-bit, stereo .wav

files.

Select the correct song category using

the [SELECT] button.

You can cycle through the available categories

(Aud, Sng, USr, and PrE) with each press of

the button; however, Aud and Sng are shown

only when a USB flash drive has been plugged

into the instrument. If you wish to play an Import

Song (001 to 999), be sure to choose the corre-

sponding category.

Use the [-/NO] and [+/YES] buttons to

select a song number, “rnd” (random),

or “ALL”.

If necessary, press the [-/NO] and [+/YES] buttons

together to show Import Songs (001 to 999).

MIDI and audio songs

MIDI songs contain data created by recording the actions of playing and releasing keys—in other words, they do not con-

tain actual audio. This data is similar to sheet music in that it indicates the keys that should be played, as well as when and

how hard they should be played, in order to reproduce a specific piece of music. Using this data, your digital piano’s tone

generator can recreate the sound of the recorded performance. MIDI songs are smaller than audio songs because they

contain less data; in addition, they also allow you to change the Voice used for playback and a number of other parameters.

In contrast, audio songs contain actual recordings of the sound of a performance, and they store audio data in much the

same way as a cassette tape or digital voice recorder. Audio songs can be played back on portable music players and

many other types of device, making it easy for you to let others hear what you have played.

Automatic start when you play any key

Using your digital piano’s Auto Start function, you

can have it start playback as soon as you play a key.

To activate this function, press and hold the [PLAY/

STOP] button for at least one second. The [PLAY/

STOP] button will begin to flash at the current tempo

to indicate that the instrument is on standby for a key

to be played. (If you wish to deactivate the Auto Start

function, again press and hold the [PLAY/STOP] but-

ton for at least one second.) The current song will start

automatically as soon as you play a key.

Starting and stopping using a pedal

If you have connected a pedal unit* (see page 12) to

your digital piano, you can configure either the center

or left pedal to operate in the same way as the control

panel’s [PLAY/STOP] button using the corresponding

Function parameter (page 40). This can be very useful

if you wish to start or stop playback without removing

your hands from the keyboard. (*: Sold separately.)

P-255 Owner’s Manual

Recording Keyboard Performances

Your digital piano features the following two different methods for recording your keyboard performances. These

methods can be used as described below depending on your requirements.

MIDI recording

When you record a performance using MIDI, it will be saved on the instrument or a USB flash drive as a MIDI

song (SMF format 0). This method allows you to record two parts separately, meaning that you could, for exam-

ple, create a song by recording the left-hand part and then recording the right-hand part. Alternatively, you could

combine the two parts of a duet to form a song. What’s more, you can also re-record one of the parts if necessary

and even change Voices and tempo. Up to ten MIDI recordings can be stored on the instrument itself.

Audio recording

Performances recorded in audio format are saved on a USB flash drive in the form of an audio song. This method

does not support the recording of individual parts. Audio recordings created using your digital piano are saved in

44.1-kHz, 16-bit, stereo .wav format, which is the same as standard CD-quality audio. For this reason, you can

easily move them to a portable music player for playback using a computer. The total available duration of record-

ing depends on the size of the USB flash drive being used. The instrument itself supports individual recordings of

up to 80 minutes in length.

If necessary, plug a USB flash drive into

the [USB TO DEVICE] terminal.

Songs in MIDI format can be recorded either on

the instrument itself or on a USB flash drive.

Audio songs must be recorded on a USB flash

drive. Be sure to read the section “Working with

USB flash drives” (page 30) before recording on a

USB flash drive.

Select the recording method.

 To record in MIDI format:

Press the [SELECT] button as many times as nec-

essary to show “USr” if you wish to record on the

instrument itself or “Sng” to record on a USB

flash drive.

 To record in audio format:

Press the [SELECT] button as many times as nec-

essary to show “Aud” (for saving your recording

on a USB flash drive).

Select a song number for the recording

using the [-/NO] and [+/YES] buttons.

• U.00 to U.09 .... MIDI-format User Songs stored

on the instrument itself

• S.00 to S.99 .... MIDI-format User Songs stored

on a USB flash drive

• A.00 to A.99 .... Audio-format User Songs

stored on a USB flash drive

If you activate Record mode without selecting a

song number, your performance will be recorded

to the currently selected song. If, however, the cur-

rent song is an audio-format Import Song, an A-

type song number will be selected; alternatively, a

U-type song number will be selected in the case of

an MIDI-format Import Song. Meanwhile, if a

Preset Song is currently selected, a U-type song

number will be selected for recording. If the corre-

sponding song already contains data, it will be

overwritten.

tant precautions below.

For more information about the handling of USB

devices, refer to the owner’s manual of the USB device.

 Compatible USB devices

• USB flash memory

Other USB devices such as a computer keyboard or

mouse cannot be used.

The instrument does not necessarily support all com-

mercially available USB devices. Yamaha cannot guar-

antee operation of USB devices that you purchase.

Although USB devices 1.1 to 3.0 can be used on this

instrument, the amount of time for saving to or loading

from the USB device may differ depending on the type

of data or the status of the instrument.

Before purchasing a USB device for use with this

instrument, please visit the following web page:

http://download.yamaha.com/

 Connecting a USB device

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 con-

nected in the proper direction.

Using USB Flash Memory

By connecting the instrument to a USB flash memory,

you can save data you’ve created to the connected USB

flash memory, as well as read data from the connected

USB flash memory.



Number of USB flash memories that can be used

Only one USB flash memory device can be connected

to the [USB TO DEVICE] terminal.

 Formatting USB flash memory

You should format the USB storage device only with

this instrument (page 33). A USB storage device for-

matted on another device may not operate properly.

 To protect your data (write-protect)

To prevent important data from being inadvertently

erased, apply the write-protect provided with each USB

flash memory. If you are saving data to the USB flash

memory, make sure to disable write-protect.

 Turning off the instrument

When turning off the instrument, make sure that the

instrument is NOT accessing the USB flash memory by

playback/recording or file management (such as during

Save, Copy, Delete and Format operations). Failure to

do so may corrupt the USB flash memory and the data.

• The rating of the [USB TO DEVICE] terminal is a maximum

of 5V/500mA. Do not connect USB devices having a rating

above this, since this can cause damage to the instrument

itself.

• Avoid connecting or disconnecting the USB device while

executing playback/recording and file management opera-

tions (such as Save, Copy, Delete and Format), or when

accessing the USB device. Failure to do so may result in

“freezing” of the operation of the instrument or corruption

of the USB device and the data.

• When connecting then disconnecting the USB device

(and vice versa), make sure to wait a few seconds between

the two operations.

• When connecting a USB cable, make sure that the length is less than 3 meters.

NOTICE

NOTE

• The Format operation overwrites any previously existing

data. Make sure that the USB flash memory you are for-

matting does not contain important data.

NOTICE

form live. In order to provide a practical description of the connections and settings required in this type of situa-

tion, we will focus on the following two typical modes of use.

• Performing on-stage as part of a band

• Singing and playing on your own

The following description covers performances

together with other musicians on-stage at a live music

club, performing arts venue, or the like.

Stage setup and signal flow

The sound from your digital piano will be sent to a PA

mixer in order that its volume can be balanced with

that of the other instruments. From there, the mixed

sound is amplified and sent to the front-of-house

speakers so that the audience can hear it. Monitor

speakers will be placed on the floor in front of the

musicians so that they can more clearly hear their own

sound and that of the other instruments.

 Connect your foot switch or pedal.

When plugged into the [SUSTAIN PEDAL] jack, the

bundled foot switch can be used to turn on and off sus-

tain. (See page 11.)



Connect the instrument’s output to the PA mixer.

In order to be heard, your instrument will need to be con-

nected to the PA mixer’s inputs. Normally, this connec-

tion is made via a DI box (direct box) located on-stage.

As described in the note on the left, you should ensure

that your digital piano is turned off and check with the

PA operator before connecting to a DI box. When you get

his or her OK, connect the [L/L+R] and [R] AUX OUT

jacks on the instrument’s rear panel to the DI box inputs

using standard mono audio cables (sold separately).

If DI boxes are not being used, connect the [L/L+R] and

[R] AUX OUT jacks on the instrument’s rear panel to the

Performing on-stage as part of a band

Please read the following before setting up.

• Ensure that the instrument is turned off before making any

connections. In addition, you should always check with the

PA operator and wait for his or her OK before connecting or

disconnecting cables. Connection or disconnection when

the operator is not ready can damage the PA system.

• Do not turn on your digital piano as soon as you have made

all of the required connections. You should always set the

[MASTER VOLUME] slider to the MIN position and get the

OK of the PA operator before turning on or off the instru-

ment. Turning your digital piano on or off when the operator

is not ready can damage the PA system.

Sound setup

Once all of the instruments and microphones have been con-

nected, the PA operator will ask each musician in turn to

play his or her instrument. You should get ready as follows.

 Turn on your digital piano.

As described in the note on the previous page, first set

the [MASTER VOLUME] slider to the MIN position

and then check with the PA operator whether you can

turn on the instrument. When you get the OK, press

the [ ] Standby/On switch to turn it on.

 Check your settings.

Once turned on, ensure that your digital piano is set up

as follows.

•Tuned to match the other instruments (page 41).

•Auto Power-Off function disabled (page 10).

• Foot switch operating correctly as a sustain pedal (page 11).

•Reverb turned off (the PA operator will normally add the right

amount of reverb using the PA mixer).

•Sound Boost function turned on if you are finding it difficult to

make your digital piano heard within the overall mix: This func-

tion has been designed to enhance the presence of your

instrument when played in a band without making it sound any

less natural or expressive. You can choose from three different

types of sound boost. (See page 18.)

•Built-in speakers turned off if necessary: There will be no

need to use these speakers if you can hear your own sound

from an on-stage monitor speaker. (See page 44.)

 Determine the best digital-piano volumes.

When asked by the PA operator to output a sound,

play the digital piano as you would when performing

and determine the best settings for the following.

•Volume when you are playing accompaniment

•Volume when you are playing loudest, such as during a key-

board solo

•Volume of each Voice to be used

Roughly speaking, the [MASTER VOLUME] slider

should be set between 5 and 7 for playing accompani-

ment and to 8 or 9 when you need to play louder. If set

too high, your sound may become distorted; if too

low, any background noise will be more noticeable.

When the volume needs to be finely adjusted for dif-

ferent Voices or raised in order to play a solo, you

should do this yourself using the [MASTER VOL-

UME] slider. Similarly, you should use the [EQ] slid-

ers to keep the tone well balanced.

 Balance the overall sound of the band.

After the volumes of the various instruments have

been set, the PA operator will have everyone play

together in order to balance the overall sound of the

band. At this time, you should listen to the nearest

monitor speaker and ensure that you can hear every-

thing you need to in order to play well. If, for exam-

ple, you cannot hear your own sound, the singer, or

another instrument well enough, ask the PA operator

to raise the corresponding level in your monitor’s mix.

 Lock the control panel to prevent mistakes.

Your digital piano’s Panel Lock function allows you to

temporarily disable control-panel buttons to prevent

them being operated unintentionally while perform-

ing. To activate this function, press the [EFFECT] and

[SOUND BOOST] buttons together.

Note that the following will continue to operate nor-

mally when the control panel is locked.

• Standby/On switch

• [MASTER VOLUME] slider

• [EQ] sliders

• [SUSTAIN PEDAL] jack

• Pedal unit

Performing

When playing live, try to relax and listen to your mon-

itor speaker in order to perform at your best.

• If only one of the mixer’s channels is available for use with your digital piano,

connect the [L/L+R] AUX OUT jack to the corresponding input jack using a stan-

dard mono audio cable. In this configuration, your left and right signals will be

mixed and output from the instrument in mono.

Yo ur instrument should now be fully connected. The

next step will be to balance your performance sounds.

Keyboard amplifiers normally require sound to be

input in mono. For this reason, you should connect the

digital piano’s [L/L+R] AUX OUT jack to the ampli-

fier’s input using a standard mono audio cable (sold

separately). The keyboard amplifier will mix your left

and right signals and output them together in mono.

 Connect the vocal microphone

If you wish to connect the vocal microphone to a

vocal or keyboard amplifier, please refer to the

owner’s manual that came with each.

Sound setup

Before you start performing, it is advisable to check

the connections by playing and singing.

 Turn on your digital piano.

 Set volume and tone.

•Rou ghly speaking, you should set the digital piano’s [MAS-

TER VOLUME] slider to 8 or 9, and you should then adjust the

overall volume using the keyboard amplifier. If this slider is set

too high, your sound may become distorted; if too low, any

background noise will be more noticeable.

Singing and playing on your own

• If your keyboard amplifier features multiple inputs, you may be able to connect

both the vocal microphone and digital piano to it. For details, please refer to the

owner’s manual that came with it.

Please read the following before setting up.

• Ensure that the digital piano, the keyboard amplifier, and

all other devices are turned off before connecting or dis-

connecting cables. Music equipment can be permanently

Other Convenient Functions

Thanks to its digital design, the P-255 offers a range of

highly useful functions as described below. When put to

effective use, they can help make your performances

much more enjoyable.

Dual mode: Two layered Voices

Using Dual mode, each key can simultaneously produce

the sound of two different Voices. (See page 14.)

Split mode: One Voice for the left, another for the right

Yo ur digital piano’s Split mode lets you divide the key-

board at a freely selectable point and assign different

Voices to the left and right sides. (See page 14.)

Transpose

Using the Transpose function, you can shift the pitch of

keyboard notes up or down in semitone units. This allows

you to change key without having to change what you

actually play on the keyboard. (See page 16.)

Touch sensitivity

Yo ur digital piano’s touch sensitivity function allows you to

adjust the degree to which changes in the strength of

your playing are reflected in the sound produced. (See

page 45.)

Rhythm tracks

Playing along with one of the many rhythm tracks pro-

vided is almost like having your own private band. (See

page 20.)

Reverb

Adding reverb to your sound is a great way to create a

rich sense of depth and space. (See page 15.)

Effects

The digital piano’s Effect function can enhance your

sound in various different ways for more expressive per-

formances. (See page 16.)

Playing along with a recording

If you have created a song by recording yourself playing,

you can then play along with that song as an accompani-

ment. (See page 21.)

Music input from an audio player

With an audio player connected to your digital piano, you

can play along with your favorite tunes or add backing

tracks or effect sounds to your live performances. (See

page 34.)

Extensive MIDI and computer support

Yo ur digital piano can be easily integrated with other MIDI

instruments or a computer. In this way, you can output

MIDI performance data as you play, perform with voices

only found on other devices, and enhance your keyboard-

playing experience in many other ways. (See page 35.)

Support for smart-device apps

Using the specially developed app P-255 Controller, you

can set your instrument in a simpler, more intuitive man-

ner. (See page 35.)

Here at Yamaha, we are continually releasing exciting

new apps for smart devices. For details, visit the following

Pressing the [-/NO] or [+/YES] button once shows

the current setting for the selected Function

parameter.

Change the setting using the [-/NO] and

[+/YES] buttons.

If necessary, you can restore the parameter’s

default setting by pressing the [-/NO] and

[+/YES] buttons together.

Press the [FUNCTION] button to apply

your new setting.

After three seconds, the display will return to the

previous screen.

Using the Tuning setting, you can fine tune the pitch of the

entire instrument. This can be extremely useful when play-

ing your digital piano along with other instruments or

recorded music.

Using the [-/NO] and [+/YES] buttons, you can lower and

raise the pitch of the A3 key in units of approximately 0.2

Hz. The tuning value is shown as a two-digit number with

one decimal place—in other words, no value is shown for

the hundreds column.

Example: 440.2 Hz is shown as “40.2”.

•Available settings: 414.8.0 to 466.8 (Hz)

•Default setting: 440.0 (Hz)

Hertz

Hertz (Hz) is the unit of audio pitch. The pitch of a sound is

determined by the frequency of its sound waves. The Hertz unit

expresses this frequency in terms of the number of oscillations

per second.

Your digital piano supports a range of different tuning sys-

tems. While the Equal Temperament tuning system has now

become standard for pianos, a wide number of other sys-

tems were developed over the centuries before it was

adopted, and these systems invariably paved the way for the

birth of new musical styles. By selecting different tuning

systems, you can enjoy the unique harmonics of music from

the corresponding periods. In total, your digital piano can

replicate the following seven different systems.

Equal temperament

The range of pitches in each octave is divided equally into

twelve parts, with each half-step evenly spaced in pitch. Today,

this is by far the most popular tuning system for pianos.

Pure Major and Pure Minor

These two tuning systems preserve the pure mathematical

intervals of each scale, especially for triadic chords (comprising

the root, third, and fifth). These characteristics can still be heard

today in vocal harmonies—such as choirs and a cappella sing-

ing.

Pythagorean

This tuning system was devised by the famous Greek philoso-

pher Pythagoras and is created from a series of perfect fifths,

which are collapsed into a single octave. The thirds in this tun-

ing are not so smooth, but the fourths and fifths are beautiful

and suitable for some leads.

Meantone

This tuning system was created as an improvement on the

Pythagorean scale by making the major third interval smoother.

It was especially popular from the latter part of the 16th century

to the end of the 18th century, with Handel being one of its most

notable users.

Werckmeister

Kirnberger

The Werckmeister and Kirnberger tuning systems improve the

Meantone and Pythagorean tuning systems by combining them

in different ways. Both are uniquely characterized by the way in

which modulation can change the nuances of mu sical composi-

tions. Often used in the eras of Bach and Beethoven, they are

still employed today to reproduce the music of those periods on

the harpsichord.

If you select a tuning system other than equal temperament,

you will also need to specify the note on which it is based.

(You can specify a base note for equal temperament, but

this setting will have no effect. It is only relevant to other

tuning systems.)

This parameter can be used to adjust the degree to which

the digital piano reflects differences in the strength of your

playing in the sound produced.

•Available settings: 1 .......Soft: Makes it possible to produce loud

sounds when playing softly.

2 .......Medium: Replicates the standard

response of a piano.

3 .......Hard: Requires the keys to be played

•Default setting: 64

The following parameters can be used to make MIDI-

related settings and to also send them to other devices. For

more information on MIDI, please refer to the MIDI Basics

pdf manual (page 6). The MIDI settings described below

affect not only the exchange of MIDI data via the MIDI ter-

minals but also via the [USB TO HOST] terminal.

F7.1 MIDI send channel

In order for two MIDI devices to exchange data with one

another, the MIDI send channel (1 to 16) on the sending

device must match the MIDI receive channel on the receiv-

ing device. Using Function parameter F7.1, you can set the

MIDI channel on which the digital piano will send the data

you produce by playing the keyboard.

•Available settings: 1 to 16 and OFF (no data sent)

•Default setting: 1

Voice 2 from Dual mode and the left Voice from Split mode

will send data on the next channel after the one set using this

parameter. (Voice 1 and the right channel use the channel set

here.) No data is sent by any Voices when “OFF” is selected.

Song data

Yo ur digital piano does not normally send data contained in

songs via the [OUT] MIDI terminal. However, if you have

selected “1&2” as the MIDI song playback channels using Func-

tion parameter F7.3 and play a non-protected MIDI song, data

from channels 3 through 16 will be sent.

F7.2 MIDI receive channel

In order for two MIDI devices to exchange data with one

another, the MIDI send channel (1 to 16) on the sending

device must match the MIDI receive channel on the receiv-

ing device. Using Function parameter F7.2, you can set the

MIDI channel on which the digital piano will receive data

sent by another MIDI device.

•Available settings: ALL, 1 to 16, and 1&2

•Default setting: ALL

Meaning of “ALL” setting

If you set “ALL” for this parameter, all data will be received from

the sending device, regardless of its channel. This allows your

digital piano to play a multi-channel song from a sequencer or

the like.

Meaning of “1&2” setting

If you set this parameter to “1&2”, your digital piano will receive

and play only data sent on MIDI channels 1 and 2 by a

sequencer or the like.

F7.3 MIDI song playback channels

With this parameter shown on the display, you can use the

[-/NO] and [+/YES] buttons to select the playback channels

for MIDI songs.

•Available settings: ALL and 1&2

•Default setting: ALL

When “ALL” is selected, all channels (1 to 16) will be

played. If you select “1&2”, data on channels 1 and 2 will

be played, but data on the other channels (3 to 16) will be

sent to the connected MIDI device.

F7.4 Local control on/off status

Using this parameter, you can specify whether or not the

digital piano’s internal tone generator is actually to produce

sound in response to playing of the keyboard. Normally,

you would have the tone generator respond to signals from

the keyboard, and Local Control is said to be turned on in

such a case. If you turn Local Control off, the instrument’s

tone generator will be essentially disconnected from the

keyboard. In this condition, no sound will be produced in

response to playing of the keyboard and no MIDI perfor-

mance data will be sent. However, the internal tone genera-

tor will respond to MIDI data received from another MIDI

device.

•Available settings: ON and OFF

•Default setting: ON

• Changing the touch sensitivity has no effect on the weights of the keys.

• The touch sensitivity setting applies to all Voices. However, certain Voices do not

respond to differences in playing strength and are not affected by this setting.

Refer to the Voice List (page 51) for details.

• The fixed touch-sensitivity volume applies to all Voices.

F7. MIDI function settings

NOTE

• Your digital piano’s control panel settings and keyboard Voices are unaffected by

program change messages received from other MIDI devices.

• MIDI data is not received while playing demo tracks or performing file opera-

tions.

NOTE

Customizing with Function Parameters

P-255 Owner’s Manual

F7.5

Program change on/off status

MIDI Program Change messages can be sent from one

MIDI device to another in order to change its Voice. In

other words, your digital piano could use a Program

Change message to change the voice being used on a con-

nected device. (When a new Voice is selected using the con-

trol panel, the corresponding Program Change Number

would be sent.) Meanwhile, upon the receipt of a Program

Change message from a connected MIDI device, your digi-

tal piano can change the Voice being used to play the

received MIDI data (but not the Voice played via the key-

board). This parameter should therefore be set to “ON” if

you wish to send and receive MIDI Program Change mes-

sages, thereby linking Voices on the digital piano with those

on connected devices. If, however, you do not want to link

Voices in this way, you should set this parameter to “OFF”.

•Available settings: ON and OFF

•Default setting: ON

F7.6 Control change on/off status

MIDI devices use Control Change messages in order to

inform each other of damper pedal operations, volume

changes, and other actions associated with the expressive-

ness of a performance. In other words, your digital piano

could send Control Change messages via MIDI to affect the

sound of a performance being played on a connected

device. (Whenever you operate the instrument’s damper

pedal, it would send the corresponding Control Change

messages.) Meanwhile, upon the receipt of a Control

Change message from a connected MIDI device, your digi-

tal piano can change the sound of the MIDI performance

being played (but not the sound being played using the key-

board). This parameter can be used to turn on and off the

exchange of MIDI Control Change messages as appropri-

ate.

•Available settings: ON and OFF

•Default setting: ON

F7.7 Send initial setup

This parameter can be used as described below to send ini-

tial setup data—that is, the current state of control panel

settings—to a connected sequencer or other device. For

example, you could send this data before recording a per-

formance on the sequencer or device, thereby saving the

digital piano’s current settings at the beginning of the

recording. In addition, you could also send this data to the

tone generator of another instrument in order to configure it

in the same way as the digital piano’s.

Set the control panel as required.

Connect the sequencer and configure it to receive

and record the initial setup data.

Use the [FUNCTION] button to select Function

parameter F7.7.

Press the [+/YES] button to send the data.

The message “End” will be shown when the data has

been sent.

Initial setup data contains the following settings.

•Voice(s)

•Reverb type and depth

• Effect type and depth

• Split point

•Tuning system (F2.1)

•Dual balance (F3.1)

• Relative Voice detune (F3.2)

•Dual balance (F4.2)

• Certain pedal and special sound settings (F5.2 to F5.6)

Using your digital piano’s Backup function, you can save

Voice selections, reverb type, and many other settings to

ensure that they are retained when you turn off the instru-

ment. If turned on, this function will restore your previous

settings automatically when you turn on your digital piano.

If turned off, however, the settings stored in the instru-

ment’s internal memory will be lost; accordingly, the corre-

sponding defaults (page 48) will be restored when you next

turn it on. That said, performance data stored in the internal

memory, the character code setting, and the on/off status of

the Backup function will always be automatically retained.

As described below, the Backup function can be turned on

or off individually for different types of settings (i.e., Voice,

MIDI, tuning, and miscellaneous). The corresponding

Function-parameter settings will also be retained.

F8.1 Voice configuration backup

•Available settings: ON and OFF

Troubleshooting

Problem Possible cause and solution

The digital piano turns off unexpectedly.

This does not indicate a problem—the Auto Power-Off function turns off the

instrument after the set period of inactivity. If necessary, you can deactivate

this function to prevent it turning off the digital piano again (page 10).

The digital piano will not turn on.

The instrument may not have been plugged in correctly. Ensure that the power

adaptor is securely connected to the digital piano and a domestic-use, AC wall

socket (page 10).

A click or pop can be heard when turning the digital

piano on or off.

This type of noise can occur when a device is charged and does not indicate a

problem.

Noise can be heard coming from the digital piano.

Noise may be caused by interference when a mobile phone in the vicinity of

the instrument is used. Try turning off any mobile phone located close to the

digital piano.

Noise can be heard coming from the digital piano’s

built-in speakers and/or headphones when using it

with an iPad, iPhone, or iPod touch app.

n order to eliminate the risk of noise from other communication when using

the instrument with an iPad, iPhone, or iPod touch, we recommend turning on

the device’s Airplane Mode.

The overall volume is low or nothing can be heard.

The digital piano’s master volume may be turned down. Try moving the [MAS-

TER VOLUME] slider to the right (page 11).

If headphones are connected to the instrument, try unplugging them (page

11).

The digital piano’s speakers are turned off. Please turn them back on (page

44).

If local control has been turned off, try turning it back on (page 45).

The sound is distorted.

The volume has been set too high.

•Turn down the volume using the [MASTER VOLUME] slider (page 11).

•Move the [EQ] sliders downward (page 17).

•Turn off the Sound Boost function (page 18).

Pedals have no effect.

The pedal cord may not be securely connected to the [SUSTAIN PEDAL] jack

or the [PEDAL UNI

T] terminal. With the digital piano turned off, insert the

cord’s plug securely into the correct jack or terminal. When fully inserted, none

of the metal section of the plug will be visible (pages 11, 12).

The pitch or tone of a Piano Voice sounds strange

in a specific frequency range.

The instrument’s Piano Voices have been carefully designed to recreate the

sounds of a real piano as faithfully as possible. In certain frequency ranges,

therefore, harmonics may appear accentuated or the pitch may not seem quite

right; however, this does not indicate a problem.

The keyboard makes a mechanical noise when

played.

Yo ur digital piano’s keyboard has been specially designed to simulate the feel

of a real piano keyboard. Even real pianos can make a mechanical noise when

played, and this does not indicate a problem.

The USB flash drive plugged into the digital piano

freezes and/or stops working.

If a message has been shown on the display, refer to the section Display Mes-

sages (page 49) for more information. If no message has been shown, the

USB flash drive may be broken.
