Congratulations! …and thank you for purchasing the Yamaha P-150. The P-150 is a high-performance electronic piano with full-scale, weighted action keyboard, a selection of high quality piano and other useful instrument voices, and versatile performance and other advanced features which make it ideal for professional stage and studio applications, as well as for home entertainment and music study use. The P- 150’s main features include:
■ High quality AWM piano and other sounds
The P-150 features a selection of twelve high quality instrument voices generated by Yamaha’s patented AWM (Advanced Wave Memory) sound generation technology. There are several piano sounds—including a concert grand piano, with full-bodied bass tones and reverberating high notes, that accurately captures the natural characteristics of a real grand piano—plus various electric pianos, vibes, organ combinations, strings and electric and upright bass. With a maximum simultaneous “polyphonic” note output of 32 notes, the P-150 delivers uncompromising performance capabilities.
■ Organ combination editing
The P-150 comes equipped with two preset organ voices, plus organ combination editing features which let you create your own organ sounds and store them in Performances for instant recall. The organ combination editing features give you precise control over flute footages as well as attack settings.
■ Digital signal processing
The P-150 has a built-in digital signal processor that lets you apply stereo reverb, chorus, symphonic and tremolo effects to the voices, and lets you tailor the quality of the voices to suit your needs with an internal equalizer, as well as a three-band graphic equalizer on the upper panel.
■ Touch-sensitive keyboard with velocity scaling
The P-150’s full-range 88-key, weighted action piano keyboard incorporates Yamaha’s unique Action Effect II keyboard technology, which gives it the genuine feel and response of a real piano keyboard. You can even adjust the keyboard’s sensitivity level, or velocity scaling, to suit your playing style, for both internal tone generator and MIDI message transmission.
■ Dual and Split voice modes
The P-150’s Dual and Split modes let you play two voices at
once, a “main” voice and a “sub” voice, either by layering the two voices of your choice (Dual mode) or by assigning a different
voice to each end of the keyboard (Split mode). In Split mode, the key transposition values can be set independently for both main and sub voices.
■ One-touch Performance recall
The P-150 features a Performance Play mode that lets you store up to 24 Performances, or configurations of all voice, MIDI and other parameter settings, for recall at the touch of a button. This lets you instantly change your sound and entire setup as you play, or between songs in a live set. The P-150 is set at the factory with 24 Preset Performances, but you can overwrite them and store User Performances which you create yourself. The P- 150 features extensive editing and storing capabilities.
■ Master keyboard features
The P-150 offers many of the control features standard in a MIDI master keyboard, including velocity sensitivity, pitch bend and modulation wheels, an assignable CS (continuous slider), program change send and receive capabilities, MIDI transpose and merge functions, and bulk dumping and multitimbral capabilities. Plus, the P-150 gives you the option of connecting a foot controller (FC) that can be assigned MIDI and other functions in the same manner as the CS. With its powerful MIDI capabilities, the P-150 can easily feature at the heart of an expanded MIDI system.
How to Use this Manual
This owner’s manual is organized and designed to help you get set up and begin enjoying the P-150 as quickly as possible, as well as to easily locate and learn about any feature you need.

■ Location
Do not use the P-150 in locations where it will be exposed to direct sunlight, extreme temperatures, high humidity or excessive dust or vibration.
■ Handling
Avoid rough handling. Do not drop the P-150 or subject it to shock, as these can damage the instrument’s internal circuitry. Also, do not apply excessive force to the controls or terminals. When moving the P-150, first unplug the AC power cord and all other cables to prevent damage to the cords and jacks. When removing plugs from terminals, always grip the plugs directly rather than pulling on the cord.
■ Cleaning
To clean the P-150, use a slightly moist cloth and a neutral cleanser. Do not use abrasive cleansers, waxes, solvents, or chemically treated cloths, as these may damage the cabinet’s finish or dull the keys.
■ AC Power
The power requirements of your P-150 has been set to match the main power supply voltage in your area. Make sure that your local AC mains voltage matches the voltage as specified on the name plate located on the rear panel of your P-150. If you plan to use your P-150 in an area with a different voltage, be sure to use an appropriate converter. If you have any doubts about voltage compatibility, please consult your local Yamaha dealer.
■ Electromagnetic Interference
Avoid using your P-150 near televisions, radios or other devices which generate electromagnetic fields, as electromagnetic interference can cause the P-150 to malfunction, and may generate interference noise in the other devices as well.
■ Extended Disuse
Electrical storms can cause power surges which can damage the P-150’s circuitry even if the power switch is turned off. Therefore, it is best to disconnect the P-150’s power cord from the AC outlet when you will not be using it for an extended period of time.
■ Service and Modification
The P-150 contains no user serviceable parts, so never open the instrument’s cabinet or tamper with the internal circuitry or mechanisms in any way. Doing so can result in electrical shock or damage to the P-150. Refer all servicing to qualified Yamaha service personnel.
■ Backup Battery
The P-150’s internal settings are preserved by a lithium backup battery which has a life span of approximately five years. (The battery’s life span may differ, depending on the time elapsed between your P-150’s date of manufacture and the date you purchased it.) When the battery charge runs low, the “ERROR1 REPLACE BATTERY” error message will appear in the LCD screen. If this message appears, save any settings you may want to keep to an external data storage device (such as the Yamaha MDF2 Data Filer) using the bulk dump procedure, then contact a qualified Yamaha service center to have the battery replaced. Do not attempt to replace the backup battery yourself!
YAMAHA CANNOT BE HELD RESPONSIBLE FOR DAMAGE CAUSED BY IMPROPER HANDLING OR OPERATION OF THE P-150!
The LCD screen displays as illustrated in this manual are for instructional purposes only, and may appear somewhat different from your P-150’s.

This switch turns the power on and off. When the power is turned on, the mode and status designated when the power was previously turned off will still be active.
2 [PITCH] wheel
This wheel can be used to bend the pitch of the notes that you play, up or down; the wheel automatically returns to the center position when you release it. (In Dual mode, both voices are affected; in Split mode, only the main voice is affected.) When the MIDI Transmit Switch is enabled, you can use it to transmit pitch bend messages to other instruments. You can assign the pitch bend range to any value within a one-octave range.
3 [MODULATION] wheel
This wheel can be used in various ways. Normally you will use it to apply a vibrato effect to the notes that you play, with increasing intensity as you roll it upwards; the wheel remains at the specific position that you set it when you let go of it. (In Dual mode, both voices are modulated; in Split mode, only the main voice is modulated. The vibrato effect cannot be applied to Piano voices 1 ~ 4.) You can also assign it to control reverb depth or modulation speed. When MIDI transmission is enabled, you can use it to transmit modulation messages to other instruments.

1 [SPEAKER] switch
This switch lets you turn off the P-150’s internal speakers. It does not affect the output from the [OUTPUT] jacks or the [PHONES] jack.
2 [INPUT] jacks
These jacks let you input line-level signals from another electronic instrument, such as a rhythm programmer, external tone generator, or synthesizer, and monitor it through the P- 150’s internal speakers. Use the [L/MONO] jack when connecting only a single line.
3 [OUTPUT] jacks
These jacks output line-level signals which can be input directly to an external amplifier, mixer or other audio device. Use the [L/MONO] jack if your audio equipment has only one input.
4 Pedal jacks
These jacks let you connect up to three foot pedals and use them as sustain, sostenuto and soft pedals. A single FC4 footswitch is included with your P-150. If you wish to attach additional foot pedals, be sure to use only Yamaha models FC4 or FC5.
5 [FOOT CONTROLLER] jack
This jack lets you connect a foot controller (Yamaha FC7, available separately) for use as an auxiliary controller. The [FC] foot controller can be assigned to control a variety of functions, including reverb depth or modulation speed, which lets you change these parameters by foot as you play.
6 [MIDI] terminals
These terminals allow the P-150 to communicate with other MIDI devices, using standard MIDI cables. To control the P-150 using a sequencer or another keyboard, connect the MIDI out jack of the external device to the [MIDI IN] jack of the P-150. To control another device (such as a synthesizer or tone generator) using the P-150, connect the [MIDI OUT] jack of the P-150 to the MIDI in jack of the external device. The [MIDI THRU] jack simply passes the data received at the P-150’s [MIDI IN] jack through unaffected, and is used when connecting three or more MIDI devices in a series.

OVERVIEW 150-P
■ Voice Play and Performance Play Modes
The P-150 has two basic Play modes, Voice Play mode and Performance Play mode. Within each mode are various Voice and Performance parameters, or settings that you can change, which make up the sound of the selected voice and the specific operating status of the P-150.
A group of overall System settings apply to both Voice Play and Performance Play modes, and Edit mode lets you access and edit a wide variety of System and other functions, as shown in the following illustration.

EDIT MODE / STORE FUNCTIONS
As the above illustration shows, the primary difference between Voice Play mode and Performance Play mode is:
■In Voice Play mode, a single set of Performance parameter settings apply to any voice (and its specified Voice parameter settings) which you select.
■In Performance Play mode, a complete set of Performance parameters can be configured specifically for any particular voice (and its specified Voice parameter settings). The P-150 can store up to 24 Performances for instant recall.
Normally you will operate in Voice Play mode, Auto Store status (See “About Store Type”, next page)— as you select sounds and make parameter assignments as dictated by your current music session. Then you can store those settings to any of the 24 Performances, which you can then access at any time by the press of a [PERFORMANCE SELECT] button in Performance Play mode. (You can also perform bulk dump operations of Performance data to and from an external MIDI device such as the Yamaha MDF2 MIDI Data Filer.)
10
ABOUT STORE TYPE
You can choose the Store Type— Non Auto Store and Auto Store.
When Non Auto Store is selected, the store operation is always required (except when modifying System related parameters; see page 13) if you want to save the current settings.
When Auto Store is selected, all changes you make will automatically be stored without the need to perform a specific storing procedure.
The default setting for a new (or initialized) P-150 is Non Auto Store. (For information about changing the Store Type, see page 45.)
Explanations in this Owner’s Manual assume that Auto Store is selected. Therefore, the LCD illustrations herein may be slightly different than the screens on your P-150.
■ Voice Parameters
In Voice Play mode, each of the P-150’s AWM instrument voices have a set of Voice parameters that are initially set at the factory, but which you can change to suit your needs.
These include controller parameters such as pitch bend range and modulation wheel assignment, keyboard sensitivity parameters for internal or MIDI applications, and effect parameters such as reverb type and depth, modulation type and speed, and internal equalizer settings.
In Voice Play mode you can access a single set of Performance parameters and in Performance Play mode you can access 24 sets of Performance parameters. Although you can freely change the voices in Performance Play mode, only a single set of Voice parameters is available for each Performance.

■ Performance Parameters
In Performance Play mode, the P-150 has 24 sets of Performance parameters which let you configure settings for specific music situations (i.e., for a certain style of music, or a particular song, or for a practice session, or a live set, etc.). This affords you the convenience of being able to recall those settings instantly at the press of a button when in Performance Play mode.
Performance parameters include the voice selection (a set of voice parameters), keyboard Single, Dual or Split mode and settings, main and sub voice assignments, User organ combination values, transposition values, keyboard local on or off setting, MIDI transmit and receive channel numbers, plus function assignments for [PS1], [PS2], [CS] and [FC] (foot controller), the Performance name and others.
In Voice Play mode you can specify settings for a single set of Performance parameters.

■ System Settings
The P-150’s overall System settings encompass those “global” parameters which are related to the instrument as a whole, and which therefore affect both Voice Play and Performance Play modes.
These include master tuning, MIDI transmit enable, MIDI filter transmit and receive parameter settings, MIDI program change table settings, and others.

■ Editing and Storing Features
When the P-150 is in Edit mode, you can access and modify the System and other parameters.
A convenient Auto Store feature (which you can disengage) automatically stores the System settings and other parameters as you change them. Within either Voice Play mode or Performance Play mode, you can store the current set of all settings as a User Performance.
There is a fine distinction between Voice Play mode store and Performance Play mode store functions. In Voice Play mode, you can overwrite the current set of Voice and Performance parameter settings. In Performance Play mode, you can select a specific destination Performance in which to store the current Performance parameter settings. Therefore, if you select a destination Performance in which to store the current Voice Play mode Performance parameter settings, you are storing it in the Performance Play mode.
You will find it most convenient to set up your Performances in Voice Play mode, Auto Store status, since voice selection is so simple, then copy it to one of the 24 Performance memories for instant recall when you need it.
By switching into Non Auto Store status, you can be sure that your Performances are protected, and any changes you make in one will not be applied unless you specifically store, or overwrite, it. In Edit mode, the P-150 will prompt you automatically whether or not to overwrite the current changes.
You can also dump Performance data to and from external MIDI devices.
Descriptions of all parameters and details about how to access and manipulate them are provided in the appropriate sections herein. Also see the Blank Chart on page 65.

■ Setting up the P-150
Although setting up the P-150 for basic play is easy and straightforward, be sure to take heed of the Precautions on page 2 before you begin, then carefully follow the simple steps as outlined below.
P-150 SETUP PROCEDURE
Prepare a suitable location.
1. The P-150 is relatively small for an 88-key instrument, but it is very solidly built and therefore quite heavy. First you’ll want to prepare a suitable location for your P-150. Please do not hesitate to ask someone to help you take it out of the box and carefully place it on an optionally available Yamaha LP-3 keyboard stand or a sturdy table.
Plug in the power cord.
2. Next plug the P-150’s power cord into an AC outlet. Do not turn on the [POWER] switch until you have made all connections as described below.
3. Connect the sustain pedal.

Connect MIDI devices.
5. If you wish to connect the P-150 to external MIDI devices such as a rhythm programmer, tone generator or synthesizer, you will need special MIDI cables which plug into the [MIDI] jacks on the rear panel. First, however, you must determine a MIDI system configuration, based on your particular needs or desires. Some examples of MIDI system connections, along with information about MIDI, are provided on page 57.

■ Playing the Demo Songs
After setting up the P-150 and switching on the power, and before you begin exploring the instrument’s various features, you may want to listen to the three preprogrammed Demo songs which demonstrate the P-150’s exceptional sound and performance capabilities. To do so, follow the steps below.
HOW TO PLAY THE DEMO SONGS
Enter Demo Play mode.
1. Press the [REVERB] and [MODULATION] buttons simultaneously. The following screen appears.

You cannot enter Demo Play mode (or any other Play mode) when the P- 150 is in Edit mode. (The LED above the [EDIT] button will blink when the P-150 is in Edit mode.) To exit Edit mode, simply press the [EDIT] button. Also note that you will not be able to play the P-150 or use any of the Edit mode functions while a Demo song is playing.
■ Playing the Voices
Selecting and playing the voices of a new P-150 is simple, since by default the instrument starts up for the first time in Voice Play mode with initialized parameter settings, PIANO 1 voice selected.
Therefore, all you have to do is press a [VOICE SELECT] button and start playing the keyboard. Take a few minutes and try playing each of the voices and notice the rich quality and dimension of the P-150’s AWM sound, complete with the nuance of natural expression via the keyboard.
As you play, try out the [PITCH] wheel, which lets you bend notes up or down. Also try out the [MODULATION] wheel, which lets you add varying degrees of vibrato (or other effects) to the voices.
While you’re at it, try out the various reverb and modulation effects, by pressing the [REVERB] and [MODULATION] buttons once or more.
When you’re ready for more, turn the page, and find out about all the P-150 has in store.
18
You can assign a specific effect to the [MODULATION] wheel in Edit mode (see page 51) which is completely unrelated to the modulation effects available by pressing the [MODULATION] button (see page 23) once or more. Note that when the vibrato effect is assigned to the [MODULATION] wheel, you cannot apply vibrato modulation to the Piano voices 1 ~ 4. Also note that the reverb depth or modulation speed may be set at 0 for certain voices, and therefore produce no noticeable effect. (For information about changing reverb depth, see page 22. For information about changing modulation speed, see page 23.)
ENTERING AND EXITING VOICE PLAY MODE
Press the [VOICE] button.
1. When you press the [VOICE] button while the P-150 is in Performance Play mode, the LED above the [VOICE] button starts blinking, indicating that Voice Play mode is standing by waiting to be activated.

■ Single Mode
When the P-150 is in Single mode, you can select and play any one of the 12 voices over the full range of the keyboard. You can also apply and adjust reverb and modulation effects, and adjust the graphic equalizer settings.
In Single mode, the LED above the currently selected [VOICE SELECT] button lights, and the name of the currently selected Single voice appears in the LCD screen.
SELECTING A SINGLE VOICE
Press a [VOICE SELECT] button.
To select a voice you need only press any of the 12 [VOICE SELECT] buttons.
Voices and Polyphony
The P-150’s voices are high quality samples of real musical instruments generated by Yamaha’s exclusive AWM (Advanced Wave Memory) tone generation process.
All of the voices have 32-note polyphony, which means that a maximum number of 32 notes can be played simultaneously. This is crucial for achieving uncompromising sound and performance when using a sustain pedal, where certain notes must hold over others as you play, until you release the sustain pedal.
There is an extra dimension to some of the P-150’s voices. Two of the PIANO voices have special stereo settings, which are capable of 16-note polyphonic output. Also, the BASS voice has both ELECTRIC BASS and acoustic UPRIGHT BASS settings.
The following table provides an overview of each preset AWM voice.

■ Reverb Effects
The P-150’s internal DSP digital signal processor generates three types of realistic reverb effects, or simulated ambient environments, which you can apply to the voices.
These include ROOM, which simulates the natural reverberations of sound in a normal-sized room, STAGE, which simulates the natural reverberations of sound in a night club, and HALL, which simulates the natural reverberations of sound in a relatively large concert hall.
As you select each voice you will notice that a specific reverb effect is already assigned to it, indicated by a lit LED to the left of the name of the selected reverb type. These are the initial default assignments set at the factory, but you can select any reverb effect you wish for each voice, or even turn the reverb effect off. You can also change reverb depth on the spot.
SELECTING A REVERB TYPE
Press the [REVERB] button once or more.
When you press the [REVERB] button repeatedly, the reverb types will be selected in order as follows: ROOM, STAGE, HALL, then OFF. (No lit LED represents Off status.)

You can also select the reverb type and depth settings in Edit mode (see page 52).
Note that each time you select a reverb type, a message will briefly display in the LCD screen, as follows.
REVERB DEPTH QE 2 <>
This temporary message displays the current depth level for the reverb type that you just selected, between 0 and 7.
You can easily change the depth level for the currently selected reverb type.

CHANGING REVERB DEPTH
Hold the [REVERB] button and move the [DATA ENTRY] slider 1. (or press [–1/NO] or [+1/YES]).
As soon as you move the [DATA ENTRY] slider (or press [–1/NO] or [+1/YES]) the REVERB DEPTH screen appears.

DATA ENTRY
If you move the [DATA ENTRY] slider upward, the depth level increases; if you move the [DATA ENTRY] slider downward, the depth level decreases.
A value of 7 will produce the largest number of reverberations, whereas a value of 0 will effectively turn the reverb off.
Release the [REVERB] button.
2. After a moment, the voice name will reappear in the screen.
Try different settings and play the keyboard and notice the difference between high and low reverb depth level settings, and the P-150’s wide variety of reverb options.
In Voice Play mode, a different reverb type and depth can be selected for each voice. When you play two voices in either Dual or Split mode, the P-150 will apply the main voice reverb type and depth setting to both voices, and ignore any settings which you may have made for the sub voice. For more information about main and sub voices, see page 25.
■ Modulation Effects
The P-150’s internal DSP digital signal processor generates three types of modulation effects which you can apply to the voices. (Note: These modulation effects are unrelated to the vibrato effect which you can apply to voices using the [MODULATION] wheel. For details about the vibrato effect, see page 52.)
These include CHORUS, a modulated delay which effectively makes a voice sound like more than one instrument is being played, SYMPHONIC, a more pronounced chorus effect, and TREMOLO, a rotating speaker effect.
As you select each voice you will notice that most have a specific modulation effect already assigned to them, indicated by a lit LED to the left of the name of the selected modulation effect type. These are the initial default assignments set at the factory, but you can select any modulation effect you wish for each voice, or even turn the modulation effect off. You can also change modulation speed on the spot.
SELECTING A MODULATION TYPE
Press the [MODULATION] button once or more.
When you press the [MODULATION] button repeatedly, the modulation types will be selected in order as follows: CHORUS, SYMPHONIC, TREMOLO, then OFF. (No lit LED represents Off status.)
