the speed or distance of communications and in some cases interrupt
communications.
• The speed of signal transfer and the distance at which communication
is possible differs according to the distance between the
communicating devices, the presence of obstacles, radio wave
conditions and the type of equipment.
• Yamaha does not guarantee all wireless connections between this unit
and devices compatible with Bluetooth function.

By using this instrument with the smart device app “Smart Pianist,” you can fully enjoy various functions, such as
playing along with a favorite song, or performing with a band or ensemble. Try installing the app to your smart
device and connect with this instrument to take advantage of those added features. For connection, refer to
page 24.
For details on the app and compatible devices, see the website below or search “Yamaha Smart Pianist” on a web
search engine.
https://www.yamaha.com/kbdapps/
A number of songs, including popular, classical and lesson songs, are pre-installed to this instrument. Smart
Pianist allows you to view the music notation (score) of these songs. For people who have difficulty reading
notation, the Stream Lights function (page 32) shows which key to play next. Just press the keys at the right time
as indicated by the moving lights above the keys.
Moreover, by using the Guide function, you can practice at your own pace since Song playback pauses and waits
for you to play the correct notes. It also allows you to practice by one-hand, or repeatedly practice a specified
range of the song.
The app also includes an “Audio to Score” function, which automatically creates a piano accompaniment score
from songs on your smart device. Even without a score, you can enjoy playing piano accompaniment to a song.

Main Features – A World of Piano Performance and Control with Smart Pianist –
This instrument features a wide variety of instrumental Voices, including piano, organ, guitar, saxophone and
more. It also allows you to layer two Voices, or play different Voices in the right- and left- hand sections.
Moreover, the Style function provides dynamic backing band accompaniment, even when you’re playing by
yourself, and features a wide number of patterns in various genres to match your performance. You can even
connect a microphone and sing along with your own performance—and has luxurious harmony functions that
allow you to automatically create vocal chorus backing for yourself, even when you’re singing alone.
The piano Voices have been created with samples of Yamaha’s flagship CFX concert grand piano and the world
renowned Bösendorfer* concert grand piano. On Smart Pianist, the Piano Room function reproduces the way
sound echoes based on the environment (such as a concert hall), and the subtle changes in sound due to the
opening or closing of the lid of a grand piano—letting you customize the piano sound to your exact liking.
*Bösendorfer is a subsidiary company of Yamaha.
NOTE
All screen examples shown here have been captured from the app with the latest specifications as of the publishing date. The screens
and the specifications may be updated for improvement.

CAUTION
• Hold the key cover with both hands when opening or closing it. Do not release it until it is fully opened or closed. Be careful to
avoid catching fingers (yours or others, especially children’s) between the cover and the unit.
• Do not place anything (such as metal objects or pieces of paper) on top of the key cover. Small objects placed on the key cover
may fall inside the unit when the cover is opened and may be nearly impossible to remove. Once inside, they could cause
electric shock, short circuit, fire or other serious damage to the instrument.
NOTICE
Do not rest your weight on, or place heavy objects on the instrument, especially around the key cover and the music rest. Doing
so can cause damage or malfunction of the key cover.

Auto Power Off function
To prevent unnecessary power consumption, this instrument features an Auto Power Off function that
automatically turns the power off if the instrument is not operated for a specified period of time. The
amount of time that elapses before the power is automatically turned off is approximately 30 minutes by
default; however, you can change the setting from [Utility] → [System] on Smart Pianist.
NOTICE
Any data which are not saved will be lost if the power automatically turns off.
NOTE
You can enable/disable the Auto Power Off function by using the [FUNCTION] button (page 30).
What is Grand Expression Modeling?
On an actual acoustic piano, subtle changes in the sound can be produced by changing your playing touch from
when you press a key to when you release it. For example, when you press a key all the way to its bottom, the key
hits the keybed underneath and the noise reaches the strings, changing the sound slightly. Furthermore, the tone
when the damper is lowered onto strings to mute the sound is changed by how quickly you release the key. The
Grand Expression Modeling technology recreates these subtle changes in the sound that respond to your touch.
This allows you to add accents by playing strongly or add resonance by playing softly to produce superbly
expressive sound. A crisp tone can be heard when playing staccato as well as a lingering sound produced when
releasing the keys slowly.
On this instrument, Grand Expression Modeling is effective only for the Voices of “CFX Grand” and “Bösendorfer.”
Disabling Auto Power Off (simple method)
Turn the power on while holding down the lowest key on the keyboard. The instrument starts up with the Auto
Power Off function disabled.

Starting Up
To adjust the volume, use the [MASTER VOLUME] slider located at the right
of the panel. Play the keyboard to check the sound while you adjust the
volume.
CAUTION
Do not use the instrument at a high volume level for a long period of time, or your hearing may
be damaged.
Intelligent Acoustic Control (IAC)
IAC is a function which automatically adjusts and controls the sound quality according to the overall
volume of the instrument. Even when playing the instrument with the overall volume turned down, it
permits both low sounds and high sounds to be clearly heard. IAC is effective only from the sound output
of the instrument speakers. This function is set to on by default; however, you can turn it on or off, and set
the depth from [Utility] → [Sound Setting] on Smart Pianist.
This instrument is equipped with three foot pedals. Before using the
instrument, rotate the adjuster under the pedal until it comes in firm
contact with the floor surface so that the pedal box does not rattle or
give way when you step on the pedals.
By default, the following functions are assigned to each pedal. You
can also assign other functions such as “Style Start/Stop” to the
pedals from [Utility] → [Pedal Setting] on Smart Pianist.
NOTICE
When moving the instrument, rotate the adjuster until it separates from the floor
surface.
NOTE
The pedals are protected with vinyl covers when shipped from the factory. Remove the covers from the pedals before using to ensure
optimum use of the pedal effects.
Damper pedal (right pedal)
When you press the damper pedal, the notes you play have a longer sustain.
Pressing this pedal while you play a VRM Voice (page 23) recreates the
characteristic string resonance of a real acoustic piano. You can use the Half-pedal
function with this pedal.
Adjusting the Master Volume
Using the pedals
Half-pedal function
The Half-pedal function allows you to use half-damper techniques, in which the
damper is pressed somewhere between all the way down and all the way up. In this
half-damper state (on a real piano), the damper felts only partially mute the strings.
This function lets you delicately and expressively control the damper muting, and
create subtle nuances in your performance, by finely controlling the point at which
pressure on the pedal affects the damper muting. The point is called “Half Pedal
Point” and can be set in the [Piano Room] or [Utility] → [Pedal Setting] on Smart
Pianist.

GP Response Damper (CSP-295GP/CSP-295 only)
The damper pedal of the CSP-295GP/CSP-295 has been designed to provide enhanced tactile response and,
when pressed, is much closer in feel to the pedal of an actual grand piano. It makes it easier to physically
experience the half-pedal point and more easily apply the half-pedal effect than other pedals.
Sostenuto pedal (center pedal)
If you play a note or chord on the keyboard and press the sostenuto pedal
while holding the note(s), the notes will sustain as long as the pedal is held.
All subsequent notes will not sustain.
NOTE
While the sostenuto (center) pedal is held, a sustained (non-decaying) type of Voice such as organ
or strings may sound continuously without decay after the notes have been released.
Soft pedal (left pedal)
The soft pedal reduces the volume and slightly changes the timbre of notes played while the pedal is
pressed. The soft pedal will not affect notes that are already playing when it is pressed.
NOTE
When a Voice other than piano (such as Jazz Organ) is selected, a specific function appropriate for the Voice is automatically assigned to
the left pedal.
Connect a pair of headphones to the
[PHONES] jacks. Since this instrument is
equipped with two [PHONES] jacks, you can
connect two pairs of headphones. If you are
using only one pair, insert the plug into either
of these jacks.
CAUTION
Do not use the headphones for a long period of time at a
high or uncomfortable volume level, since this can cause
permanent hearing loss.
NOTE
When a plug is connected to the [PHONES] jack, no sound will come out from the instrument's speakers. If you are using an adaptor
plug, be sure to remove this as well when unplugging the headphones.
Using the headphone hanger
A headphone hanger is included in the instrument package so that you can
hang the headphones on the instrument. Attach the headphone hanger by
using the included two screws (4 × 10 mm) at the left front side as shown in
the illustration.
NOTICE
Do not hang anything other than the headphones on the hanger. Otherwise, the instrument
or the hanger may be damaged.

Reproducing the natural sensation of sound distance (even when using headphones)
This instrument features two advanced technologies that allow you to enjoy exceptionally realistic, natural
sound, even when listening on headphones.
Binaural Sampling
Binaural Sampling is a method that uses two special microphones set at the ear position of a performer and
records the sound from a piano as it would actually be heard. Listening to the sound with this effect
through headphones gives the impression of being immersed in the sound, as if it was actually emanating
from the piano. Moreover, you can enjoy the sound naturally for a long time without ear fatigue. When the
“CFX Grand” or “Bösendorfer” (page 30) is selected, connecting the headphones automatically enables the
binaural sampling sound.
Sampling
A technology which records the sounds of an acoustic instrument and then stores them to the tone generator to be played based on
information received from the keyboard.
Stereophonic Optimizer
Stereophonic Optimizer is an effect which reproduces the natural sound distance, like with the sound of
Binaural Sampling, even though you are listening to it on headphones. When one of the VRM Voices other
than “CFX Grand” or “Bösendorfer” is selected, connecting the headphones automatically enables the
Stereophonic Optimizer.
To see which Voices are VRM Voices, refer to the Data List on the website.
What is VRM?
On an actual acoustic piano, if you press the damper pedal and play a key, not only does the string of the pressed
key vibrate, it also causes other strings and the soundboard to vibrate, each influencing the rest and creating a rich
and brilliant resonance that sustains and spreads. The VRM (Virtual Resonance Modeling) technology featured in
this instrument reproduces the complicated interaction of both string and soundboard resonance faithfully using a
virtual musical instrument (physical modeling), and makes the sound more like a real acoustic piano. Since
instantaneous resonance is made at the moment according to the state of the keyboard or pedal, you can vary the
sound expressively by changing the timing of your pressing the keys, and the timing and depth of your pressing the
pedal.

Playing the Instrument Stand-alone
You can play the keyboard by using various instrumental Voices. While holding down the [FUNCTION]
button, press one of the C0 – A0 keys to select the desired Voice (page 30). To reset to the default Voice
(CFX Grand), press the [FUNCTION] button.
NOTE
If you use Smart Pianist, the Voices can be played via three keyboard parts: Main, Layer and Left. These playing modes allow you to play
just one single Voice (Main part) over the entire keyboard, layer a different Voice (Layer part) to the Main part, or play a different Voice in
the left-hand areas of the keyboard by turning the Left part on. When the Left part is turned on, the Stream Lights lights up at the point
(called Split Point) which divides the keyboard into the left-hand and right-hand areas.
This section explains how to play the preset Songs (page 31).
1While holding down the [FUNCTION] button, press one of the C1 – A1 keys.
During Song playback, the Stream Lights indicate the notes you should play and when you play
them. As the lights “descend,” play the indicated key when the light reaches the bottom, nearest
the key.
The Stream Lights speed and the on/off status can be set from [Song] → (Song select) →
[Setting] → [Playback] on Smart Pianist.
NOTE
To change the tempo, refer to page 34.
2Press the [FUNCTION] button to stop playback.
The ten preset Songs are played back continuously until you stop playback.
NOTE
You can use the Guide function on Smart Pianist. When it is turned on, you can practice at your own pace — since the
playback of other parts will wait for you to play the notes correctly.

Playing the Instrument Stand-alone
You can change the MIDI channel for transmitting MIDI messages of your keyboard performance from the
MIDI [OUT] terminal to a connected MIDI device. The three keyboard parts are changed in conjunction.
The default settings are as follows:
• Main part: MIDI port 1, channel 1
• Layer part: MIDI port 1, channel 2
• Left part: MIDI port 1, channel 3
While holding down the [FUNCTION] button, press the F6 or G6 key to change the channels up or down
by one. To restore the default settings, simultaneously hold down the [FUNCTION] button and press the
F 6 key.#
Example
NOTE
The channel of the Main part is the basis and can be changed over a range of 1 to 8. When the Main part's channel is 8, pressing
“Channel up 1” (press the G6 key while holding down the [FUNCTION] button) does not change the channels of all three parts. When the
Left part's channel is 8 (Main part is 6), pressing “Channel up 1” restores the Left part's channel to 1.
The Audio Loopback function allows you to set whether audio input sound from the smart device or
computer is output to a smart device or a computer or not along with the performance played on the
instrument. To output the audio input sound, set the Audio Loopback to on. For example, if you want to
record the audio input sound as well as the sound played on the instrument by using the connected
computer or smart device, set this to on. If you intend to record only the sound played on the instrument by
using the computer or smart device, set this to off.
To turn this function on/off, simultaneously hold down the [FUNCTION] button and press the G 6 or A6 #
key.
NOTE
• The audio input sound via the Bluetooth Audio function (page 25), USB Audio Interface function (page 40) or the Wi-Fi connection with
Smart Pianist (page 27) can be output. The sound is output to the smart device or the computer connected via the USB Audio Interface
function or Smart Pianist connected via Wi-Fi. The sound cannot be output to a Bluetooth device.
• When Audio Recording by using Smart Pianist, the audio input sound from the connected smart device or computer is recorded when
this is set to on, and not recorded when set to off.

Connections
Using an external stereo system for listening to sounds from the instrument
You can connect a stereo system to amplify the instrument’s sound by using the AUX OUT [R]/[L/L+R]
jacks. The sound input from the [AUX IN] jack and the [MIC/LINE IN] jack is output at the same time.
NOTICE
• To avoid possible damage, first turn on the power to the instrument, and then to the external device. When turning off the
power, do in reverse: first turn off the power to the external device, and then to the instrument.
• Since this instrument’s power may automatically be turned off due to the Auto Power Off function (page 20), turn off the power
to the external device, or disable Auto Power Off when you do not intend to operate the instrument.
• Do not route the output from the AUX OUT jacks to the [AUX IN] jack. If you make this connection, the signal input at the [AUX
IN] jack is output from the AUX OUT jacks. These connections could result in a feedback loop that will make normal
performance impossible, and may even damage the equipment.
NOTE
• When connecting a mono device, use only the [L/L+R] jack.
• Use an appropriate adaptor plug if the input jack of the powered speaker does not match the phone plug of the audio cable.
• Use audio cables and adaptor plugs having no (zero) resistance.
• When you are monitoring the sound output via the AUX OUT jacks from headphones connected to the instrument, we recommend that
you set the Binaural Sampling and Stereophonic Optimizer functions (page 23) to off. These can be turned on or off from [Utility]
[Sound Setting] [Binaural] on Smart Pianist.
The FC4A/FC5 footswitch or the FC7 foot controller (sold separately) can be connected to [AUX PEDAL]
jack. A footswitch can be used for switching functions on and off, while a foot controller controls
continuous parameters such as volume. The function of the connected pedal can be set from [Utility] →
[Pedal Setting] on Smart Pianist.
NOTE
• Make sure to connect or disconnect the pedal only when the power is off.
• Do not press the pedal while turning the power on. Doing this changes the recognized polarity of the pedal, resulting in reversed
operation.
