PLEASE KEEP THIS MANUAL
92-BP (bottom)

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:
Water warning

• 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.

• 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.
• Never insert or remove an electric plug with wet hands.

ENGLISH

Power supply/AC power adaptor

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

Location

• 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 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 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.

• 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.
• Before moving the instrument, remove all connected adaptor and other cables.
• Use only the stand specified for the instrument. When attaching the stand or
rack, use the provided screws only. Failure to do so could cause damage to the
internal components or result in the instrument falling over.
• Do not place objects in front of the instrument's air vent, since this may prevent
adequate ventilation of the internal components, and possibly result in the
instrument overheating.

P-90 PRECAUTIONS

Connections

Saving data

• 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. 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.

ENGLISH

Handling caution

Saving and backing up your data
• Depending upon the Backup Functions (page 42) settings, internal data is
retained for about 1 week after the power is turned off. If the period is exceeded,
the data will be lost. Be sure to turn the power switch on for a few minutes at
least once a week. The data could be lost due to malfunction or incorrect
operation. Save important data to external media such as the Yamaha MDF3
MIDI data filer.

Backing up the external media
• To protect against data loss through media damage, we recommend that you
save your important data onto two external media.

• 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 operate the instrument for a long period of time at a high or
uncomfortable volume level, since this can cause permanent hearing loss. If you
experience any hearing loss or ringing in the ears, consult a physician.

Yamaha cannot be held responsible for damage caused by improper use or modifications to the instrument, or data that is lost or destroyed.
Always turn the power off when the instrument is not in use.
Even when the power switch ([STANDBY/ON] 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.
Make sure to discard used batteries according to local regulations.

P-90 Application Index

Features
The Yamaha P-90 Electronic Piano offers unmatched sonic realism and natural grand-piano type playability as well as
Yamaha’s original “AWM Dynamic Stereo Sampling” tone-generation technology for rich, musical voices, and a special
“Graded Hammer” keyboard that provides graded key weight and response throughout the keyboard range.
The GrandPiano1 and 2 voices feature samples recorded from a full concert grand piano. The GrandPiano1 voice features
three velocity-switched samples (Dynamic Sampling), special “Sustain Sampling” that samples the unique resonance of
an acoustic grand piano’s soundboard and strings when the sustain pedal is pressed, and “Keyoff Samples” that add the
subtle sound produced when the keys are released. The P-90 comes much closer to the sound of a true acoustic piano.

CAUTION
When turning the power on, first turn the P-90’s power on and then turn
the power on of the external amplifier/speaker system.
When turning the power off, simply reverse the order.

Since the P-90 does not contain speakers, you will need to connect external audio
equipment or use headphones in order to hear its sounds.

Instrument amplifier

4 [PHONES] jacks (1/4-inch stereo phone jacks)
You can connect headphones to these jacks.
Since there are two [PHONES] jacks, you can connect two pairs of headphones so that two people can listen. (If connecting only one pair of headphones, you may use either jack.)

CAUTION
Do not use the P-90 at a high volume level for a long period of time, or
your hearing may be damaged.

5 [SUSTAIN] jack

SUSTAIN

You can connect the included pedal to this jack. While this pedal is pressed,
notes you play will be sustained even if you take your finger off the key. Since
half-pedaling is supported, pressing the pedal more deeply will produce
longer sustain. On the [GRAND PIANO 1] voices (including its variation),
pressing this pedal will also add sympathetic resonances of the sound board
and strings (sustain sampling).

Turn off the power before connecting or disconnecting the pedal.

You can adjust the depth of the sound board and string resonance effect (page 39).

P-90 Before using the P-90

When you press the pedal
here, the notes you play
before you release the pedal
have a longer sustain.

[BRILLIANCE]
This control can be used to change the tonality or “timbre” of the sound output.
The control range is from MELLOW to BRIGHT.

[REVERB]

ENGLISH

This control enables you to select various digital reverb effects that would add extra
depth and expression to the sound to create a realistic acoustic ambience.
OFF:
When no reverb effect is selected, no REVERB indicator is lit.
ROOM: This setting adds a continuous reverb effect to the sound, similar to the
acoustic reverberation you would hear in a room.
HALL 1: For a “bigger” reverb sound, use the HALL 1 setting. This effect simulates
the natural reverberation of a small-size concert hall.
HALL 2: For a truly spacious reverb sound, use the HALL 2 setting. This effect simulates the natural reverberation of a large concert hall.
STAGE: Simulates the reverb of a stage environment.

When the BRILLIANCE is set to
BRIGHT, the overall sound will
be slightly louder. If the MASTER VOLUME is set at a high
level the sound may become
distorted. If so, lower the MASTER VOLUME level.

The default reverb type (including OFF) and depth settings are
different for each voice.

Procedure
Pressing the [REVERB] button repeatedly toggles the reverb on and off.
The indicators light in sequence each time the [REVERB] button is pressed. No effect is
produced when all indicators are off.
Even if the REVERB effect is OFF, a “Soundboard Reverb” effect will be applied when
the [GRAND PIANO 1] voices are selected.
Adjusting Reverb Depth
Adjust the reverb depth for the selected voice by using the
[–/NO] [+/YES] buttons while holding the [REVERB] button. The depth range is from 0 through 20. The current

Touch Sensitivity – [TOUCH]
You can select four different types of keyboard touch sensitivity — HARD, MEDIUM, SOFT or FIXED
— to match different playing styles and preferences.
HARD:
MEDIUM:
SOFT:
FIXED:

Requires that the keys be played quite hard to produce maximum loudness.
Produces a fairly “standard” keyboard response.
Allows maximum loudness to be produced with relatively light key pressure.
All notes are produced at the same volume no matter how hard the keyboard is played.
You can adjust the volume.

This setting does not change
the weight of the keyboard.

Normal setting = MEDIUM

The touch sensitivity type will
become the common setting for
all voices. However, the touch
sensitivity settings may have little or no effect with certain
voices that are not normally
responsive to keyboard dynamics. (Refer to the “Preset Voice

Transposition – [TRANSPOSE]
The P-90’s Transpose function makes it possible to shift the pitch of the entire keyboard up or down
in semitone intervals to facilitate playing in difficult key signatures, and to let you easily match the
pitch of the keyboard to the range of a singer or other instruments. For example, if you set the
transposition amount to “5,” playing key C produces pitch F. In this way, you can play a song as
though it were in C major, and the P-90 will transpose it to the key of F.

The beat indicator flashes
at the current tempo.

Adjusting the tempo
The tempo of the metronome and user song recorder playback (the recorder is
described in the next section) can be set from 32 to 280 beats per minute by
using the [TEMPO/FUNCTION# ▼, ▲] buttons (when the [FUNCTION] button

The volume of the metronome
can be adjusted via the Metronome Volume function in Function mode (page 39).

2. Stop the metronome.
Turn off the metronome by pressing the METRONOME [START/STOP] button.

P-90 Selecting & Playing Voices

Recording Your Performance
The ability to record and play back what you’ve played on the P-90
keyboard can be an effective practice aid. You can, for example, record
just the left-hand part, and then practice the right-hand part while
playing back the recorded left-hand part. Or, since you can record up
to two tracks separately, you could record the left- and right-hand parts
separately, or record both parts of a duet and hear how they sound
when played back. The P-90’s two-track Song Recorder allows the
recording of one User Song.

You can record your performance (audio data) to a cassette tape recorder or other
recording device via the OUTPUT connector (page 10).

ENGLISH

Recording vs. Saving:
The format of performance data
recorded on a cassette tape differs from that of data recorded
on the P-90. A cassette tape
records audio signals. The P-90
“saves” information regarding
note timing, voices, and a
tempo value, but not audio signals. When you play back
recorded songs, the P-90 produces sound based on the
saved information. Therefore,
recording on the P-90 may be
more accurately called “saving
information.” However, this book
often uses the word “recording”
because it seems to make more
sense.

Procedure
CAUTION
Notes on recording
All user song recorder data will be retained in memory for about one week after
the power is turned off. If you want to keep your recorded data for longer periods of time, turn the power on for a few minutes at least once a week.
It is also possible to store the data to an external MIDI storage device such as the
Yamaha MIDI Data Filer MDF3 by using the Bulk Data Dump function described
on page 42.

1. Make all the initial settings.
Before you begin to record, select the voice you want to record (or voices if you
will be using Dual or Split mode). Make any other desired settings (tempo,
reverb, etc.) as well. You might also want to set the volume.
You can also adjust the playback volume using [MASTER VOLUME].

recorded.

ENGLISH

Press the [REC] button to engage Record Ready
mode. Recording does not actually start yet.
The [TRACK1] or the [TRACK2] indicator flashes in
red.
The amount of memory available for recording will
be shown on the LED display in approximate kilobytes, and the right-most dot on the LED display
will flash at the current METRONOME tempo setting.

For more recording information,
see page 28.

The record track indicator will
begin to flash when the recorder
memory is almost full. If the
memory becomes full during
recording, “FUL” will appear on
the display and recording will
stop automatically. (All recorded
data up to that point will be
retained.)

5. Stop recording.
Press either the [REC] or SONG [START/STOP] button to stop recording.
The indicator of the recorded track will glow green to indicate that it now contains data. (Record mode is disengaged automatically.)

Pressing the SONG [START/
STOP] button to start recording,
then pressing it again to stop
recording will erase all previously-recorded data on the
selected track.

6. Play back the recorded performance.
Press the SONG[START/STOP] button to play back the recorded performance.
To stop playback in the middle of a song, press the SONG[START/STOP] button.

Repeat Step 1 on page 26 if you wish to change the previous settings.
2. Re-engage Record Ready mode.
Press the [REC] button, again.
The selected track’s indicator flashes in red.

If you want to change the
tempo, time signature, reverb
type, or effect type when rerecording a track or when
recording to another track, do
so after you engage Record
Ready mode (step 2).

Follow the procedure from Step 4 above to re-record.
You cannot re-record in the
middle of a song.

Equal:
One octave is divided into twelve equal intervals. Currently the
most popular piano tuning scale.
PureMajor/PureMinor:
Based on natural overtones, three major chords using these
scales produce a beautiful, pure sound. They are sometimes
used for chorus parts.
Pythagorean:
This scale, designed by Pythagoras, a Greek philosopher, is
based on the interval of a perfect 5th.
The 3rd produces swells, but the 4th and 5th are beautiful and
suitable for some leads.
MeanTone:
This scale is an improvement of the Pythagorean in that the
swell of the 3rd has been eliminated. The scale became popular during the late 16th century through the late 18th century,
and was used by Handel.
WerckMeister/KirnBerger:
These scales combine Mean Tone and Pythagorean in different ways. With these scales, modulation changes the impression and feel of the songs. They were often used in the era of
Bach and Beethoven. They are often used today to reproduce
the music of that era on harpsichords.

Sub-mode

In any MIDI control setup, the MIDI channels of the
transmitting and receiving equipment must be matched
for proper data transfer. This parameter enables you to
specify the channel on which the P-90 receives MIDI
data.
Setting range: ALL, 1&2, 1 – 16
Normal setting: ALL

ALL:
A “Multi-timbre” Receive mode is available. It allows simultaneous reception of different parts on all 16 MIDI channels,
enabling the P-90 to play multi-channel song data received
from a music computer or sequencer.
1&2:
A “1&2” Receive mode is available. It allows simultaneous
reception on channels 1 and 2 only, enabling the P-90 to play
1 and 2 channel song data received from a music computer or
sequencer.

Program change and other like channel messages received
will not affect the P-90’s panel settings or the notes you play
on the keyboard.

No MIDI reception occurs when Demo/Preset Song mode is
engaged.

F8.1: MIDI Transmit Channel Selection
In any MIDI control setup, the MIDI channels of the
transmitting and receiving equipment must be matched
for proper data transfer.
This parameter enables you to specify the channel on
which the P-90 transmits MIDI data.
Setting range: 1 – 16, OFF (not transmitted)
Normal setting: 1

In Dual mode, Voice 1 data is transmitted on its specified
channel. In Split mode, right voice data is transmitted on its
specified channel. In Dual mode, Voice 2 data is transmitted
on the next greater channel number relative to the specified
channel. In Split mode, left voice data is transmitted on the
next greater channel number relative to the specified channel.
In either mode, no data is transmitted if the transmit channel is
set to “OFF”.

Demo/preset song data and recorder playback data are not
transmitted via MIDI.

P-90 Detailed Settings – [FUNCTION]

F8.3: Local Control ON/OFF
“Local Control” refers to the fact that, normally, the P-90
keyboard controls its internal tone generator, allowing
the internal voices to be played directly from the keyboard. This situation is “Local Control On,” since the
internal tone generator is controlled locally by its own
keyboard.
Local control can be turned OFF, however, so that the P90 keyboard does not play the internal voices, but the
appropriate MIDI information is still transmitted via the
MIDI OUT connector when notes are played on the keyboard. At the same time, the internal tone generator
responds to MIDI information received via the MIDI IN
connector.
Setting range: ON/OFF
Normal setting: ON

F8.4: Program Change ON/OFF

F8.6: MIDI Transmit Transpose

Normally the P-90 will respond to MIDI program
change numbers received from an external keyboard or
other MIDI device, causing the correspondingly-numbered voice to be selected on the corresponding channel
(the keyboard voice does not change). The P-90 will normally also send a MIDI program change number whenever one of its voices is selected, causing the
correspondingly-numbered voice or program to be
selected on the external MIDI device if the device is set
up to receive and respond to MIDI program change
numbers.
This function makes it possible to cancel program
change number reception and transmission so that
voices can be selected on the P-90 without affecting the
external MIDI device.

This function allows the MIDI note data transmitted by
the P-90 to be transposed up or down in semitone increments by up to plus or minus 12 semitones. The pitch of
the P-90 itself is not affected.
Setting range: -12 – 0 – 12 (in semitones)
Normal setting: 0

For information on program change numbers for each of the
P-90’s voices, refer to page 56 in the MIDI Data Format section.

Setting range: ON/OFF
Normal setting: ON

F8.5: Control Change ON/OFF
Normally the P-90 will respond to MIDI control change
data received from an external MIDI device or keyboard,
causing the voice on the corresponding channel to be
affected by pedal and other “control” settings received
from the controlling device (the keyboard voice is not
affected).
The P-90 also transmits MIDI control change information when the pedal or other appropriate controls are
operated.
This function makes it possible to cancel control change
data reception and transmission so that, for example, the
P-90’s pedal and other controls can be operated without
affecting an external MIDI device.

For information on control changes that can be used with the
P-90, refer to the MIDI Data Format on page 56.

Setting range: ON/OFF
Normal setting: ON

This function causes all the current P-90 panel settings
(selected voice, etc.) to be transmitted via the MIDI OUT
terminal. This is particularly useful if you will be recording performances to a MIDI sequence recorder, such as
the Yamaha MIDI Data Filer MDF3, which will be used
to control the P-90 on playback. By transmitting the P-90
panel settings and recording them on the MIDI sequence
recorder prior to the actual performance data, the P-90
will be automatically restored to the same settings when
the performance is played back.

ENGLISH

F8.7: Panel/Status Transmit

Setup Data:

1. Connect the P-90 via MIDI to the device to which the setup
data was transmitted previously.
2. Start sending the setup data from the device.
The P-90 automatically receives the setup data, which will be
reflected in the panel settings.
(For the data to be accepted, the P-90 that receives the setup
data should be the same model as the one that transmitted
the setup data to the sequencer.)

F8.8: Bulk Data Dump
You can save current song data on the P-90 as MIDI bulk
data by transferring it to a connected MIDI data filer
(such as an MDF3) or a sequencer. To play back the saved
song data, send the bulk data back from the storage
device to the P-90 and follow the usual playback procedure.

Bulk Data:
A complete set or extended sequence of data

was previously transmitted.
2. Start sending the data from the device.
The P-90 automatically receives the data from the unit. (At
this time, any data previously stored in the P-90 will be
erased.)
Then, follow the usual playback procedure.
(For the data to be accepted, the P-90 that receives the data
should be the same model as the one from which the data
was once transmitted to the MIDI data filer.)

F9. Backup Functions
Backup:
You can back up some settings, such as voice selection and
reverb type, so that they will not be lost when you turn off the
power to the P-90.
If the backup function is turned on, the settings at power off
are effective. If the backup function is turned off, the settings
in memory are erased when you turn off the power. In this
case, when you turn on the power to the unit, the default settings (the initial settings) will be used. (The factory setting
default list is found on page 55.)
However, the backup settings themselves, and the contents of
the user song recorder memory, are always backed up.

CAUTION
Even if the backup function is turned on via one of the
functions described below, the data will be retained in
memory for only about one week if the power is not
turned on during this time. If the backup period is
exceeded, all settings will be reset to their default values. If you want to retain the backup settings for
longer periods, be sure to turn the power on for a few
minutes at least once a week.

You can turn the backup function on or off for

P-90 About MIDI

Connecting a Personal Computer
You can enjoy computer music data on the P-90 by connecting a computer to the [TO HOST] (or
MIDI) connector.

There are three methods by which to connect the P-90 to a personal computer:
1. Connect the serial port on the computer to the P-90’s [TO HOST] connector (page 46).
2. Use a MIDI interface and the P-90’s MIDI connectors (page 47).
3. Use the USB port on the computer and the UX256, UX96, or UX16, a USB interface (page 48).
For more information, refer to the specified pages.

ENGLISH

When the P-90 is used as a tone module, performance data with voices that are not found on the P-90 will not be played
correctly.

When connecting the P-90 to a personal computer, first turn off the power to both the P-90 and the computer before you
connect any cables or set the [HOST SELECT] switch. After making the connections and switch settings, turn on the
power to the computer first, then to the P-90.
If you do not use the [TO HOST] connector of the P-90, make sure you disconnect the cable from the jack. If the cable
is left connected, the P-90 may not function properly.

will appear in the display if the host computer is not turned on, the connecting cable is not properly connected,
the [HOST SELECT] switch is not in the proper position, or the MIDI driver or MIDI application is not active. In this situation, turn the power off to both the P-90 and the computer, and check the cable connection and the position of the
[HOST SELECT] switch. Once the connection and [HOST SELECT] switch position is verified, turn the power of the
computer on first, then the P-90, and check whether the MIDI driver and MIDI application function properly.
When the [HOST SELECT] switch is set to “PC-1,” PC-2,” or “Mac,” you can use the [TO HOST] connector, but the MIDI
connectors are disabled since no data transfer occurs via the MIDI connectors. On the other hand, when the [HOST
SELECT] switch is set to “MIDI,” you can use the MIDI connectors, but not the [TO HOST] connector since no data is
transferred via the [TO HOST] connector.

P-90 Connecting a Personal Computer

1. Connecting the serial port on the computer to the P-90’s [TO HOST] connector
Connect the computer’s serial port (RS-232C or RS-422) to the P-90’s [TO HOST] connector.
With this connection, the P-90 functions as a MIDI interface. Therefore, you do not need a special MIDI interface.

Troubleshooting
Possible Cause and Solution

The P-90 does not turn on.

The P-90 has not been plugged in properly. Insert the adaptor plug into an AC outlet
and the adaptor socket into the unit securely. (page 8).

A click or pop is heard when the power is
turned on or off.

This is normal when electrical current is being applied to the instrument.

Noise from the speakers or headphones is
audible.

The noise may be due to interference caused by the use of a mobile phone in close
proximity to the P-90. Turn off the mobile phone, or move it further away from the P-90.

The overall volume is low, or no sound is
heard.

• The Master Volume is set too low. Set it to an appropriate level using the [MASTER
VOLUME] control.
• Make sure that Local Control (page 40) is ON.

The foot pedal has no effect, or the sound
continuously sustains even when the foot
pedal is not pressed.

The pedal cord may not be properly connected. Make sure to securely insert the pedal
cord into the [SUSTAIN] jack (page 10).

The foot pedal seems to produce the opposite
effect. For example, pressing the foot switch
cuts off the sound and releasing it sustains
the sounds.

The polarity of the foot pedal is reversed. Make sure that the foot pedal plug is properly
connected to the [SUSTAIN] jack before turning on the power.
Do not press the pedal while turning the power on.

• Receipt of the XG SYSTEM ON message causes reinitialization of relevant parameters and Control Change values. Allow
sufficient time for processing to execute (about 50 msec)
before sending the P-90 another message.
• XG Native Parameter Change message may contain two or
four bytes of parameter data (depending on the parameter
size).
• For information about the Address and Byte Count values,
refer to Table 1 below. Note that the table’s Total Size value
gives the size of a bulk block. Only the top address of the
block (00H, 00H, 00H) is valid as a bulk data address.
