Contents
Taking Care of Your PDP-400 ............ 1
The Panel Controls ............................... 2
Your PDP-400 will give you years of playing pleasure if you observe the simple rules given below:
1
1. Avoid Humidity & Heat
Avoid placing the PDP-400 in areas that are subject to excessive humidity or heat. Do not leave the instrument near heaters
or in a car exposed to direct sunlight, for example.
2. Avoid Dust & Moisture
Avoid locations in which the instrument is likely to be exposed
to excessive dust or moisture.
3. Power-off Before Connecting
Connections between the PDP-400 and any other device must
be made with both pieces of equipment turned off.
4. Handle With Care
Never apply excessive force to the controls, connectors or
other parts of your PDP-400, and avoid scratching or bumping
it with hard objects. Further, always turn the POWER switch off
after use.
5. Clean Carefully
Clean the cabinet and keys of your PDP-400 only with a clean,
slightly damp cloth. A neutral cleanser may be used if desired.
Never use abrasive cleansers, waxes, solvents or chemical
dust cloths since these can dull or damage the finish.
6. Never Tamper With the Internal Circuitry
Never open the PDP-400 cabinet and touch or tamper with the
internal circuitry. Tampering with the circuitry can result in electrical shock!
7. Electric Interference
Since the PDP-400 contains digital circuitry, it may cause interference if placed too close to radio or television receivers. If
this occurs, move the instrument further away from the affected
equipment.
8. Check Your Power Supply
Make sure that your local AC mains voltage matches the voltage specified on the name plate on the rear panel. In some
areas a voltage selector may be provided on the rear panel.
Make sure that the voltage selector is set for the voltage in
your area.
9. Name Plate Location
The PDP-400 name plate, including the unit’s serial number, is
located on the rear panel of the main unit.
10.Handling Floppy Disks
Yamaha Disk Orchestra Collection and Style Disk are writeprotected, and therefore cannot be used to save songs. To save
Performance Memory songs from the Performance Memory, a
blank floppy disk should be used (one blank disk is supplied
with the PDP-400).
Taking Care of Your Floppy Disks
■ Do NOT eject the disk during recording or playback, or at
any time when the disk drive lamp is lit. Doing so may damage both the disk and the FDD.
■ Do NOT turn the PDP-400 on or off while the disk is in the
drive.
■ Always eject the disk before turning the PDP-400 off.
■ When ejecting a floppy disk from the disk drive:
• To eject a floppy disk, press the eject button slowly as far as
it will go. Then when the disk Is fully ejected, remove it by
hand.
• The disk may not be ejected properly if the eject button is
pressed too quickly or if it is not pressed in far enough. (The
eject button may become stuck halfway with the disk extending from the slot by only a few millimeters). If this is the
case, do not attempt to pull out the partially ejected disk.
Doing so may damage the disk drive mechanism and/or the
floppy disk. To remove a partially ejected disk, try pressing
the eject button once again or push the disk back into the
slot, then repeat the eject procedure carefully.
■ Do not insert anything but floppy disks into the disk
drive. Other objects may cause damage to the disk
drive or floppy disk.
■ Use only double-sided double density (2DD) 3.5-inch
floppy disks with the PDP-400.
Precautions Regarding Floppy Disk Use
■ Never open the disk’s shutter. Dirt or dust on the
Internal magnetic surface will cause data errors.
■ Never leave disks near a speaker, TV, or other device that emits a strong magnetic field.
■ Do not store disks in places exposed to direct sunlight or sources of high temperature.
■ Do not place heavy objects such as books on top of
a disk.
■ Avoid getting the disks wet.
■ Be sure to store the disks in environmental condi-
tions as specified below:
• Storage temperature: 4° to 53°C (39° to 127°F).
• Storage humidity: 8 to 90% relative humidity.
• Store in an area free from dust, sand, smoke, etc.
■ Be sure to apply the disk label at the proper position.
When changing the label never cover the old label
with a new label; always remove the old label first.
Head Cleaning
The head of the disk drive unit will get dirty as you use
it eventually causing data errors. If this occurs, clean
the head with a 3.5 inch head cleaning disk (available
from most computer supply stores).
Data Backup
It is recommended that you copy your recorded songs
to another disk for backup (see page 39). If the original
disk is damaged or your song is deleted, the backup
disk can be used instead of the original.
Attach the supplied music stand to the PDP-400 by inserting it into the groove
at the rear of the instrument’s top panel.
DAMPER
FOOT SWITCH
■The Power Switch
POWER
The supplied FC4 foot switch should normally be connected to the DAMPER
jack. It (or an optional FC4 or FC5 foot switch) can also be connected to the
FOOT SWITCH jack — see page 14 for details.
In some areas the power cord must be connected to a socket on the rear panel of
the instrument before being plugged into an AC wall outlet. A plug adaptor may
also be provided to match the pin configuration of the AC wall outlets in your area.
Make sure the power cord is properly connected to both the instrument and a convenient AC wall outlet, then press the [POWER] switch located to the left of the
keyboard once to turn the power on. Press the [POWER] switch again to turn the
power off.
When the power is initially turned on, the PIANO voice selector LED will
light, the POP style selector LED will light, and “72” will appear on the TEMPO
display.
■Headphones
A pair of stereo headphones can be plugged in here for private practice or latenight playing. The internal speaker system is automatically shut off when a pair of
If you will be using the PDP-400 with an external sound system connected via
the AUX OUT jacks, the internal amplifier and speaker system can be turned off by
using the rear-panel SPEAKER ON OFF switch.

The PDP-400 has several volume controls that give
you extra versatility in creating the required sound.
The MASTER VOLUME control adjusts the overall volume of sound

produced by the PDP-400. It also adjusts headphone volume when a pair of headphones is plugged into the PHONES jack.
Initially set the MASTER VOLUME control about half way between the
“MIN” and “MAX” settings. Then, when you start playing, adjust the control for
the most comfortable listening level.

“COSMIC” is an echo effect in which the sound seems to “bounce” around in the
stereo sound field.

The depth of the selected reverb effect can be increased or decreased by press-
ing the TEMPO [▲] or [▼] button while holding the [REVERB] button. The reverb depth is shown on the TEMPO display while the [REVERB] and [▲] or [▼]
buttons are held. The reverb depth range is from “0” (no effect) to “15” (maximum depth).
• Reverb depth is initially set to “8” when the power is turned on (this setting can be

recalled during reverb depth selection by pressing the TEMPO [▲] and [▼] buttons simultaneously).
• The TEMPO [▲] and [▼] buttons allow two-speed scrolling: press lightly to scroll
through the values slowly, or press firmly to scroll rapidly.
The PDP-400 has “32-note polyphony” which
means you can normally play up to 32 notes at once.
This number varies, however, according to the functions being used.
● The number of available notes is further reduced if the performance memory or a
Disk Orchestra Collection disk is being played at the same time. Further variation
occurs with “1-layer” and “2-layer” voices. The polyphony is halved with 2-layer
voices: voices 56 (JAZZ ORGAN 2), 58 (COSMIC 1), and 60 (COSMIC 3).
The PDP-400 also offers keyboard touch response, so the volume and timbre of
notes played can be controlled according to how “hard” you play the keys. The
amount of variation available depends on the selected voice.
The PITCH wheel can be used to “bend” the pitch of notes up or down while play-
ing. The PITCH wheel is self-centering, and will automatically return to center position — i.e. normal pitch — when released. The PITCH wheel will affect both voices
in the Dual and Split modes. Pitch-bend data is also transmitted via the MIDI OUT
connector along with the note data. The range of the PITCH wheel is plus or minus
one whole tone.
Modulation Wheel
MODULATION
MAX
MIN
The MODULATION wheel can be used to apply “modulation” in the form of a
vibrato effect to notes played on the keyboard. More modulation is applied as the
wheel is rolled upward. Unlike the self-centering PITCH wheel, the MODULATION
wheel will stay where it is set so you can set any degree of modulation you like and
leave it that way. Please note, however, that when you select a different voice the “normal” modulation level for that voice will initially be recalled regardless of the position
of the MODULATION wheel. The MODULATION wheel will affect both voices in
the Dual and Split modes. Modulation data is also transmitted via the MIDI OUT connector along with the note data.
offer a range of advanced expressive capabilities.
DAMPER
FOOT SWITCH
■Damper Pedal
The supplied FC4 foot switch functions as a damper pedal when connected to
the rear-panel DAMPER jack. The damper pedal functions in the same way as a
damper pedal on an acoustic piano. When the damper pedal is pressed notes played
have a long sustain. Releasing the pedal immediately stops (damps) any sustained
notes.
■Foot Switch (Multi-function)
FOOT SWITCH
SOFT
SOSTENUTO
START/STOP
SOLO STYLEPLAY
An optional FC4 or FC5 foot switch connected to the rear-panel FOOT
SWITCH jack provides a number of functions which can be selected using the
[FOOT SWITCH] button and indicators. Each time the [FOOT SWITCH] button
is pressed the next function on the function “list” is selected and the corresponding
indicator will light.
Pressing the soft pedal subtly reduces the volume and slightly changes the timbre of notes played. The SOFT function is automatically selected whenever the
POWER switch is turned on.
If you play a note or chord on the keyboard and press the sostenuto pedal while
the note(s) are held, those notes will be sustained as long as the pedal is held (as if
the damper pedal had been pressed) but all subsequently played notes will not be
sustained. This makes it possible to sustain a chord, for example, while other notes
are played “staccato.”
The SOSTENUTO function cannot be selected while the SOLO STYLEPLAY
feature is operating.
The foot switch performs the same function as the panel [START/STOP] but-
tons. For details on the START/STOP function, refer to the “Accompaniment”
section on page 18, 19.
● Solo Styleplay .........................................................................................................................................
For details on the SOLO STYLEPLAY function see “SOLO STYLEPLAY” on
page 25 (the SOLO STYLEPLAY pedal function can only be selected when theSOLO STYLEPLAY feature is in use).
• The damper, soft, and sostenuto pedal functions do not affect the DRUMS voice.
● The pan (stereo) position of the voice played on the key-
board can be adjusted by moving the RHYTHM volume
control while holding the [MIDI/TRANSPOSE] button.
The pan position is shown on the TEMPO display, from
“PL6” for full left at the “MIN” control position, through
“PC” for center, to “Pr6” for full right at the “MAX”
control position. This can be used to produce a broader
ensemble sound with the Performance Memory multitrack
recording feature.
Each voice has a preset pan setting (indicated by “Pd”
on the TEMPO display) which is automatically set when
the power is first turned on.
NOTES
• The “Pd” keyboard scale pan default for some voices places the
treble-register sound to the right and the bass-register sound to the
left. Using a different PAN setting places the entire voice, low and high
notes included, at the same position.
• The DRUMS voice has a preset PAN setting which cannot be changed.
Transposition
The PDP-400’s TRANSPOSE function makes it
possible to shift the pitch of the entire keyboard up or
down in semitone intervals up to a maximum of six
semitones. “Transposing” the pitch of the PDP-400
keyboard makes it easier to play in difficult key signatures, and you can simply match the pitch of the keyboard to the range of a singer or other instrumentalist.

● Use the TEMPO[▲] and [▼] buttons to select the desired
degree of transposition while holding the [MIDI/TRANS-POSE] button.
The amount of transposition selected is shown on the
TEMPO display as follows:
NOTES
• Press the [▲] and [▼] buttons simultaneously while holding the [MIDI/
TRANSPOSE] button to restore normal keyboard pitch.
• Transpose is always set to Normal when the power is turned on.
• The TRANSPOSE function does not affect the DRUMS sound.
• The TEMPO [▲] and [▼] buttons allow two-speed scrolling: press
lightly to scroll through the values slowly, or press firmly to scroll rapidly.
• Notes below and above the original 88-key range of the PDP-400
sound one octave higher and lower, respectively.
Pitch control makes it possible to tune the PDP-400 over a ±50-cent range (approximate) in
approximately 1.2-cent or 1-hertz intervals. A hundred “cents” equals one semitone, so the tuning
range provided allows fine tuning of overall pitch over a range of approximately a semitone. Pitch
control is useful for tuning the PDP-400 to match other instruments or recorded music.
ZTo tune up (raise pitch), hold the A-1 and B-1 keys simultaneously (A-1 and B-
1 are the two lowest white keys on the keyboard) and press any key between C3
and B3. Each time a key in this range is pressed the pitch is raised by approximately 1.2 cents, up to a maximum of about 50 cents above standard pitch. To
raise the pitch in 1-hertz increments press the TEMPO [▲] button instead of
the C3-B3 keys. The TEMPO[▼] button can also be used to tune down while
the A-1 and B-1 keys are held.
ZTo tune down (lower pitch), hold the A-1 and A#-1 keys simultaneously and
press any key between C3 and B3. Each time a key in this range is pressed the
pitch is lowered by approximately 1.2 cents, up to a maximum of about 50 cents
below standard pitch. To lower the pitch in 1-hertz increments press the
TEMPO[▼] button instead of the C3-B3 keys. The TEMPO[▲] button can
also be used to tune up while the A-1 and A#-1 keys are held.

44.2 442.5...... 442.74
The approximate pitch of A3 is shown on the TEMPO display in Hertz while
the pitch control function is in operation. The total display range is from
approximately 427 hertz (-50 cents) to 453 hertz (+50 cents).
The dots to the right of each figure in the display are used to provide a general
idea of fractional pitches.
The PDP-400 has 24 “styles” that can be used as a basis for rhythm accompaniment, or fully
orchestrated rhythm, bass, and chord accompaniment (see “Auto Bass Chord” on page 20).

■Single-finger Accompaniment
SINGLE FINGER accompaniment makes it simple to produce accompaniment using major, seventh, minor and minor-
seventh chords by pressing a minimum number of keys in the ABC section of the keyboard. The automatic accompaniment
consists of rhythm, bass and chords.

As soon as you play any chord (up to 4 notes) on the lower keyboard (up to the

When this advanced auto-accompaniment mode is engaged (press the [FULL KEY-
BOARD] button so that its indicator lights) the PDP-400 will automatically create ap-
propriate accompaniment while you play just about anything, anywhere on the keyboard:
chords, a bass line, arpeggiated chords, a melody line. You don’t have to worry about
specifying the accompaniment chords. Although Full-keyboard ABC is designed to work
with many songs, some arrangements may not be suitable for use with this feature. Try
playing a few simple songs in the Full-keyboard ABC mode to get a feel for its capabilities.
• Chord detection occurs at approximately 8th-note intervals. Extremely short chords —
NOTES
less than an 8th note in length — may therefore not be detected.
The Conventional Full-keyboard ABC mode can be engaged by pressing the [SIN-
GLE FINGER] and [FINGERED] buttons simultaneously (both indicators will light).
In this mode the split point is de-activated and notes played anywhere on the keyboard
are detected and used to determine the harmonization of the accompaniment. In the Conventional Full-keyboard ABC mode, chord detection is possible when at least three notes
are played anywhere on the keyboard.
• The Dual or SPLIT mode can be used with Full-keyboard ABC.
NOTES
• The Full-keyboard and Conventional Full-keyboard ABC modes will be disengaged and
the Fingered mode will be engaged if Solo Styleplay is turned on.
• Solo Styleplay will automatically be turned off whenever the Full-keyboard or Conventional Full-keyboard ABC mode is engaged.
• Press the [FULL KEYBOARD] button so that its indicator goes out when you want to exit
from the FULL-KEYBOARD ABC mode. To exit from the Conventional Full-keyboard
ABC mode press the [SINGLE FINGER] or [FINGERED] button twice.
The RHYTHM, CHORD 1, CHORD 2, and BASS volume controls can be used to
adjust the volume of the corresponding accompaniment parts when using ABC. In general, CHORD 1 controls rhythmic chords while CHORD 2 controls more decorative
chords (arpeggios, etc.). The volume of the keyboard can be independently controlled by
using the BASS volume control while holding the [MIDI/TRANSPOSE] button.
• Some styles may not use all four parts: RHYTHM, CHORD 1, CHORD 2, and BASS.
NOTES
• Usually the CHORD 1 and CHORD 2 parts will not play simultaneously in the Fullkeyboard ABC mode to prevent possible conflict with the melody. The sound of the
silent part can be restored by changing the setting of the corresponding volume control
— CHORD 1 or CHORD 2.
■Changing the ABC Split Point
SINGLE FINGER
C3
The ABC split point can be set at any key by pressing the desired key while holding
the [SINGLE FINGER] or [FINGERED] button.
The default split point — F#2 — will always be set automatically whenever the
Some accompaniment notes may be automatically muted if they interfere musically
with what is being played by the right hand. This mute function can be enabled or disabled via the Utility mode “Mute” function described on page 43. The mute function is
normally enabled (default).
When playing a 7th chord in a minor key, the ABC system will automatically shift a 9th
note down to the octave, and a 6th note to the 5th when the “Minor Harmonization” utility
function described on page 43 is turned on. The default setting for this function is off.
• Minor Harmonization will not function in the Full-keyboard ABC mode.

While the song is playing, hold the [MIDI/TRANSPOSE] and press the
[PHRASE REPEAT] button once at the beginning of the section to be repeated
(the “A” point) and again at the end of the section to be repeated (the “B” point).
Repeat playback will begin automatically from the A point as soon as the B point
“A” point“B” point
has been specified. The programmed A and B points are retained until a different
song number or mode is selected, and the A-B phrase can be selected again for
repeat playback after playback has been stopped by following the Phrase Repeat
Press the [oPAUSE] button to temporarily stop DISK ORCHESTRA playback.
Press the [oPAUSE] button again (or the [START/STOP] button) to resume play-
back from the same point.
During DISK ORCHESTRA operation the [r REW] and [f FF] buttons func-
tion as follows:
■ While playback is stopped or paused the [r REW] and [f FF] buttons can be
used to step backward or forward through the song a measure at a time. Either button can also be held for continuous stepping in the specified direction.
■ During playback the [r REW] and [f FF] buttons allow you to move rapidly in
the specified direction for as long as the button is held. No sound is produced during [r REW] operation.
• Using the [rREW] button may cause the voice, tempo, and/or volume to change.
NOTES
• The [oPAUSE], [rREW] and [fFF] buttons do not function while a guide mode is
engaged.
If the FOOT SWITCH pedal is set for START/STOP operation using the [FOOT
SWITCH] button, it functions as a pause/next phrase control during DISK ORCHES-
TRA playback: press once to pause, and again to continue from the beginning of the
next phrase (refer to the DISK ORCHESTRA COLLECTION book that comes with
the DISK ORCHESTRA COLLECTION disk for phrase locations).
• The pedal pause/next phrase function will not operate if the guide, phrase repeat, or

all songs repeat modes are active.
■DISK ORCHESTRA COLLECTION Disk Copy
The [ORCH/3-10TR] and [RHYTHM] parts of songs from DISK ORCHESTRA COLLECTION disks — the disk
supplied with the PDP-400 and others available from Yamaha — can be copied to separate disks by following the
“Copying Disk Orchestra Disks” instructions given on page 39 of the “Disk Control” section. Data copied in this way
can be played back and manipulated via the Performance Memory (page 31) — you can, for example, record your own
[RIGHT/1TR] and [LEFT/2TR] parts.
• Disk Orchestra Collection phrase marks are not copied.
NOTES
■Playing Other Types of Music Data
In addition to Disk Orchestra Collection disks, the PDP-400 can also play back Yamaha Disklavier PianoSoft™ disks, disks
containing Yamaha ESEQ format sequence data, and disks containing songs recorded in Standard MIDI File format (format 0 only).
It is possible to change the track 1/2 voice by using the panel voice selectors during playback of Disk Orchestra Collection
and Disklavier PianoSoft disks. In this case the playback voice will become the same as the voice played via the keyboard. The
playback voice cannot be changed when playing back other type of disks (the keyboard voice can be changed).
The phrase repeat function described above can only be used with Disk Orchestra Collection disks. A-B repeat can be used
with any type of data. The guide function can only be used with ESEQ files.
The [ORCH/3-10TR] part select button can also be used with all types of data: with files other than General MIDI files it
turns tracks 3 through 14 on or off, and with General MIDI Files it turns tracks 3 through 9 and 11 through 16 on or off. The
[RHYTHM] button can be used to turn track 15 on and off with file types other than General MIDI (with General MIDI files the
[RHYTHM] button turns track 10 on and off). With any type of file the individual tracks (1 through 16) can be turned on and off
as described on page 27 — tracks 11 through 16 are controlled by keys G6 through C7, respectively.
When playing files other than General MIDI files the Auto Accompaniment volume controls affect the following tracks (the
volume of General MIDI format tracks cannot be controlled):
When playing General MIDI Files the PDP-400’s internal tone generator is auto-
matically switched to the GM System Level 1 voice allocation.

Performance Memory
The PDP-400 features a built-in “sequencer” which can be used to independently record up to ten separate
parts of a single musical composition, plus a rhythm track. Each part is recorded on one of the Performance
Memory “tracks” accessed via the [RIGHT/1TR], [LEFT/2TR], [ORCH/3-10TR], and [RHYTHM] buttons. The
music data that you record is stored on a 3.5" floppy disk loaded into the PDP-400’s disk drive unit. Up to approximately 60 songs can be recorded on a single disk, depending on the amount of data contained in each
song. Before you can record, however, you must “format” a new disk, as described on page 38.
• The Performance Memory playback data is not transmitted via the MIDI OUT connector.

is available for recording, “FUL” will appear on the display.
