PRECAUTIONS

ENGLISH

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:

• 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 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.

• Do not put burning items, such as candles, on the unit.

A burning item may fall over and cause a ﬁre.

• 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:

• When removing the electric plug from the instrument or an outlet, always hold

the plug itself and not the cord.

• Unplug the AC power adaptor when not using the instrument, or during

electrical storms.

•Do not connect the instrument to an electrical outlet using a multiple-connector.

Doing so can result in lower sound quality, or possibly cause overheating in the

outlet.

•Do not expose the instrument to excessive dust or vibrations, or extreme cold or

heat (such as in direct sunlight, near a heater, or in a car during the day) to

prevent the possibility of panel disﬁguration or damage to the internal

components.

• Do not use the instrument in the vicinity of a TV, radio, stereo equipment,

mobile phone, or other electric devices. Otherwise, the instrument, TV, or radio

may generate noise.

• Do not place the instrument in an unstable position where it might accidentally

fall over.

• 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.

PRECAUTIONS

ENGLISH

• 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.

• When cleaning the instrument, use a soft, dry cloth. Do not use paint thinners,

solvents, cleaning ﬂuids, or chemical-impregnated wiping cloths.

• 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.

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.

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.

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.

OUTPUT [L][R] jacks (RCA phono jacks), [L/L+R] [R]

jacks (phone jacks)

You can use audio cables to connect an external audio device to these jacks.

The audio output of the P-90 is sent from the OUTPUT jacks, allowing you

to play it from an external audio device.

For monaural output, use

[L/L+R]

(phone jack).

CAUTION

Before connecting the P-90 to other electronic components, turn off the

power for all components. Before turning the power on or off for all com-

ponents, set all-volume levels to minimum.

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.

[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 head-

phones so that two people can listen. (If connecting only one pair of head-

phones, 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.

[SUSTAIN] jack

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).

Tu rn off the power before connecting or disconnecting the pedal.

If the foot pedal seems to produce effects opposite to your intensions, make sure

that the foot pedal plug is properly connected to the [SUSTAIN] jack before turning

on the power to the P-90. Do not press the pedal while turning on the power to the

P-90.

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

P-90 Selecting & Playing Voices

ENGLISH

[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]

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 simu-

lates the natural reverberation of a large concert hall.

STAGE: Simulates the reverb of a stage environment.

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] but-

ton. The depth range is from 0 through 20. The current

depth setting appears on the LED display while the

[REVERB] button is held.

[EFFECT]

The [EFFECT] button allows you to select an effect to give your

sound greater depth and animation.

OFF: When no effect is selected, no EFFECT indicator is lit.

CHORUS: A shimmering, broadening effect

PHASER: Adds a sweeping effect to the sound.

TREMOLO: Tremolo effect

DELAY: Echo effect

When the BRILLIANCE is set to

BRIGHT, the overall sound will

be slightly louder. If the MAS-

TER VOLUME is set at a high

level the sound may become

distorted. If so, lower the MAS-

TER VOLUME level.

The default reverb type (includ-

ing OFF) and depth settings are

different for each voice.

Procedure

Releasing the [REVERB] but-

ton changes the reverb type.

If you are changing the reverb

depth by holding the [REVERB]

button, pressing the [REVERB]

button will not change the

reverb type.

You can adjust the effect depth for the selected voice by

using the [–/NO] and [+/YES] buttons while holding the

[EFFECT] button.

The depth range is from 0 through 20. The current depth

setting appears on the LED display while the [EFFECT]

button is held.

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: Requires that the keys be played quite hard to produce maximum loud-

ness.

MEDIUM: Produces a fairly “standard” keyboard response.

SOFT: Allows maximum loudness to be produced with relatively light key pres-

sure.

FIXED: All notes are produced at the same volume no matter how hard the key-

board is played.

You can adjust the volume.

To select a touch sensitivity type press the [TOUCH] button a few times until the indica-

tor corresponding to the desired type lights (the indicators light in sequence each time

the [TOUCH] button is pressed). No indicator is lit when “FIXED” is selected.

Procedure

Changing the volume when FIXED is selected

When you select FIXED, you can set the volume for notes

played in FIXED mode by using the [–/NO] and [+/YES] but-

tons while you hold the [TOUCH] button. The current vol-

ume level appears on the display. The volume range is from 1

through 127. The default setting is 64.

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.

Use the [–/NO] and [+/YES] button while holding the

[TRANSPOSE] button to transpose down or up as required.

The amount of transposition appears on the LED display

while the [TRANSPOSE] button is held. The default transpose

setting is “0”.

The [TRANSPOSE] button indicator remains lit when a transpose setting other than

“0” is selected. Every time the [TRANSPOSE] button is pressed after that switches the

transpose function ON or OFF.

Splitting the Keyboard Range and Playing Two Dif-

ferent Voices (Split mode)

Split mode enables you to play two different voices on the keyboard — one with the left hand and

another with the right hand. For example, you can play a bass part using the Wood Bass or Electric

Bass voice with the left hand, and a melody with the right hand.

1. Engage Split mode.

Press the [SPLIT] button so that its indicator lights. The default setting (WOOD

BASE) will be selected for the left-hand voice at ﬁrst.

The Function mode provides access to a number of other Split mode functions

(page 38). (If you make no settings for Split mode functions, the appropriate

setting will be set in each voice by default.)

2. Specify the split point (the border between the

right-and left-hand range).

You can change the split point to any other key by pressing the key while hold-

ing the [SPLIT] button (the name of the current split-point key appears on the

LED display while the [SPLIT] button is held).

The split point is initially set at the F2 key by default.

If you do not need to change the split point, skip this procedure.

3. Select a voice for the right hand.

Press a voice button.

4. Select a voice for the left hand.

Press the corresponding voice button while holding the [SPLIT] button. (The

indicator of the Left Voice button will light while the [SPLIT] button is pressed.)

To turn the variation on or off for the split voice, hold the [SPLIT] button and

press the [VARIATION] button or the currently-selected voice button.

Using the Metronome

The P-90 features a built-in metronome (a device that keeps an accurate tempo) that is convenient

for practicing.

1. Start the metronome.

The metronome sound is turned on by pressing

the METRONOME [START/STOP] button.

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

indicator is dark).

Adjusting the time signature

The time signature (beat) of the metronome can be

set by using the [–/NO] and [+/YES] buttons while

holding the METRONOME [START/STOP] button.

You can set the beat to 0, 2, 3, 4, 5 or 6. The current

setting appears on the LED display while you are

holding the METRONOME [START/STOP] button.

2. Stop the metronome.

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

[EFFECT] in Split Mode

Depending on the conditions,

one effect type will take priority

over the other. The depth will be

decided according to the depth

default value of the voice combi-

nation. However, using function

F4 (page 38) you can change

the depth value for each voice

as you like. Effect depth setting

via the panel controls (i.e.

pressing the [–/NO] or [+/YES]

buttons while holding the

[EFFECT] button — see

page 20) will be applied to the

right voice only.

P-90 Recording Your Performance

ENGLISH

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.

Recording to the First Track

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 peri-

ods 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].

You can record your perfor-

mance (audio data) to a cas-

sette tape recorder or other

recording device via the OUT-

PUT connector (page 10).

Recording vs. Saving:

The format of performance data

recorded on a cassette tape dif-

fers 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 sig-

nals. When you play back

recorded songs, the P-90 pro-

duces 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.

Useful Playback Functions

Turning track playback on and off

When you select a song on the P-90, the indicators for tracks that contain

data (one of [TRACK1] [TRACK2] or both) are lit in green. While the P-90 is playing or

stopped, pressing these track buttons turns off the indicators, and the data on those

tracks is not played. Pressing the track buttons toggles track playback on and off.

Starting playback automatically when you start playing the keyboard

(Synchro Start)

You can start playback as soon as you start playing the keyboard. This is called the

“Synchro Start” function.

To engage the Synchro Start function, press the SONG [START/STOP] button while

holding a track button that is ON.

The right-most dot on the display will ﬂash at the current

tempo.

(Repeat the previous operation to disengage the Synchro

Start function.)

Playback will then start as soon as you begin playing on the keyboard.

This function is useful when you wish to match the timing of the beginning of the play-

back sound and the start of your own performance.

Tracks can be turned on or off

before or during playback.

If both tracks are turned off on

the P-90, playback will not start

(or the playback will stop).

You can adjust the volume of a

part of a song from “50 Greats

for the Piano” for which play-

back is turned off

(pages 16, 39).

During recorder playback, the

volume of a track that is turned

off will always be “0.”

If you press the SONG [START/

down a track button that is OFF,

track playback is turned on and

the Synchro Start function is

placed on stand-by.

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 popu-

lar 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 differ-

ent ways. With these scales, modulation changes the impres-

sion 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

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.

F8.2: MIDI Receive 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 receives MIDI

data.

Setting range: ALL, 1&2, 1 – 16

Normal setting: ALL

ALL:

A “Multi-timbre” Receive mode is available. It allows simulta-

neous 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.

F8.3: 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 key-

board. 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 P-

90 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 key-

board. 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. MIDI Functions

P-90 Detailed Settings – [FUNCTION]

ENGLISH

F8.4: Program Change ON/OFF

Normally the P-90 will respond to MIDI program

change numbers received from an external keyboard or

other MIDI device, causing the correspondingly-num-

bered voice to be selected on the corresponding channel

(the keyboard voice does not change). The P-90 will nor-

mally also send a MIDI program change number when-

ever 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.

For information on program change numbers for each of the

P-90’s voices, refer to page 56 in the MIDI Data Format sec-

tion.

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 informa-

tion 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

F8.6: MIDI Transmit Transpose

This function allows the MIDI note data transmitted by

the P-90 to be transposed up or down in semitone incre-

ments 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

F8.7: Panel/Status Transmit

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 record-

ing 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.

Setup Data:

Data that contains a set of panel settings for the P-90.

Procedure

1. Set up the panel controls as desired.

2. Connect the P-90 to a sequencer via MIDI, and set up

the sequencer so it can receive the setup data.

3. Engage Function mode and select .

4. Press the [+/YES] button to transmit the panel/status

data.

Receiving the transmitted 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 proce-

dure.

Bulk Data:

A complete set or extended sequence of data

Procedure

1. Record your performance on the P-90.

2. Connect the P-90 to MDF3, a MIDI data ﬁler via

MIDI, and set up the MDF3 so it will receive bulk

data.

3. Engage Function mode and select .

4. Press the [+/YES] button to begin bulk transmission.

will appear on the LED display when the data has

been successfully transmitted.

No MIDI note/panel data transmission or data reception

occurs during a bulk data dump transmit operation.

Receiving (returning) the transmitted data:

1. Connect the P-90 via MIDI to the device to which the 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.)

The reload operation cannot be executed when Demo/Preset

Song mode or the user song recorder is in operation, or when

Function mode is engaged.

For more information on transmitting and receiving bulk data

via MIDI, refer to the owner’s manual for the connected MIDI

device.

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 set-

tings (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 val-

ues. 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

each function group (each of the following

P-90 About MIDI

ENGLISH

About MIDI

MIDI (Musical Instrument Digital Interface) is a standard format for

data transmission/reception. It enables the transfer of performance

data and commands between MIDI devices and personal computers.

Using MIDI, you can control a connected MIDI device from the P-90, or

control the P-90 from a connected MIDI device or computer.

MIDI connectors

MIDI [IN]: Receives MIDI data.

MIDI [OUT]: Transmits MIDI data.

MIDI cables

Prepare dedicated MIDI cables.

[TO HOST] connector

Use this connector to connect the P-90 to a computer.

MIDI performance data and

commands are transferred in

the form of numeric values.

Since MIDI data that can be

transmitted or received varies

depending on the type of MIDI

device, check the “MIDI Imple-

mentation Chart” to ﬁnd out

what MIDI data and commands

your devices can transmit or

receive. The P-90’s MIDI Imple-

mentation Chart appears on

P-90 Connecting a Personal Computer

ENGLISH

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.

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 situ-

ation, 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

ENGLISH

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.

Connection

Use a special serial cable (page 46) to connect the computer’s serial port (RS-232C or RS-422) to the P-90’s [TO HOST]

connector.

Type of serial cables and connection pin assignments

Depending on the type of computer you connect, use one of the following serial cables.

Note for Windows users

(regarding the MIDI driver)

To transfer data via the computer’s

serial port and the P-90’s [TO

P-90 Troubleshooting

ENGLISH

Troubleshooting

Problem 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.

If appears on the display, an internal malfunction has occurred. In this case, contact your Yamaha dealer.

Data size must match parameter size (2 or 4 bytes).

When the XG System On message is received, the MIDI sys-

tem will be reset to its default settings.

The message requires approximately 50ms to execute, so

sufﬁcient time should be allowed before the next message is

sent.

(2) XG Native Bulk Data (reception only)

Data format: [F0H] -> [43H] -> [0nH] -> [4CH] -> [aaH] ->

[bbH] -> [hhH] -> [mmH] -> [llH] ->[ddH] ->...->

[ccH] -> [F7H]

• Receipt of the XG SYSTEM ON message causes reinitializa-

tion 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.
