IMPORTANT
Check your power supply
Make sure that your local AC mains voltage matches the voltage
specified on the name plate on the bottom panel. In some areas a
voltage selector may be provided on the bottom panel of the main
keyboard unit near the power cord. Make sure that the voltage selector is set for the voltage in your area. The voltage selector is set
at 240V when the unit is initially shipped. To change the setting use
a “minus” screwdriver to rotate the selector dial so that the correct
voltage appears next to the pointer on the panel.

PRECAUTIONS
PLEASE READ CAREFULLY BEFORE PROCEEDING
* Please keep these precautions 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:
• 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.
• If the power 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 electric 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:
• Only use the voltage specified as correct for the instrument. The required
voltage is printed on the name plate of the instrument.
• Before cleaning the instrument, always remove the electric plug from the
outlet. Never insert or remove an electric plug with wet hands.
• Check the electric plug periodically and remove any dirt or dust which may
have accumulated on it.
• Do not place the power 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.
• When removing the electric plug from the instrument or an outlet, always
hold the plug itself and not the cord. Pulling by the cord can damage it.
• 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.
• Remove the electric plug from the outlet when the instrument is not to be
used for extended periods of time, or during electrical storms.
• 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.
• 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 near other electrical products such as televisions,
radios, or speakers, since this might cause interference which can affect
proper operation of the other products.
• Do not place the instrument in an unstable position where it might accidentally fall over.
• Before moving the instrument, remove all connected cables.
• When cleaning the instrument, use a soft, dry cloth. Do not use paint thinners,
solvents, cleaning fluids, or chemical-impregnated wiping cloths. Also, 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.
• Take care that the key cover does not pinch your fingers, and do not insert a
finger or hand in the key cover gap.
• Never insert or drop paper or metallic or other objects between the slits of
the key cover and the keyboard. If this happens, immediately turn off the
power and remove the electric plug from the outlet and have the instrument
inspected by qualified Yamaha service personnel.
• Do not place the instrument against a wall (allow at least 3 cm/one-inch
from the wall), since this can cause inadequate air circulation, and possibly
result in the instrument overheating.
• Read carefully the attached documentation explaining the assembly process. Failure to assemble the instrument in the proper sequence might result in damage to the instrument or even injury.
• 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.
* The illustrations and displays as shown in this owner’s manual are for instruc-
tional purposes only, and may be different from the ones on your instrument.

is active. To return to the normal single-voice play mode, press any
single voice selector.
According to the voice numbering priority as shown in the diagram
on the left, lower valued voice numbers will be designated as the 1st
Voice (the other voice will be designated as the 2nd Voice).
The [STRINGS] [VARIATION] voice has a slow attack. This
voice can sometimes be used with another voice in the Dual Mode to
produce a better “blend”.
• The [VARIATION] button indicator will light if the variation is engaged for
NOTE
either or both of the dual-mode voices. While the dual mode is engaged
the [VARIATION] button can be used to turn the variation for both voices
on or off. To use the variation for only one of the voices the setting must
be made prior to engaging the dual mode.
• [REVERB] in the Dual Mode
The reverb type assigned to the 1st Voice will take priority over the other.
(If the reverb is set to OFF, the 2nd Voice’s reverb type will be in affect.)
Reverb depth setting via the panel controls (i.e. pressing the [-/NO] or [+/
YES] buttons while holding the [REVERB] button — see page 15) will be
applied to the 1st Voice only.

ROOM
This setting add a continuous reverb effect to the sound that is similar
to the type of 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 really spacious reverb sound, use the HALL 2 setting. This effect
simulates the natural reverberation of a large concert hall.

The Pedals
The YDP-121 has three foot pedals that produce a range of expressive
effects similar to those produced by the pedals on an acoustic piano.
Damper (Right) Pedal................................................................................
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.
Soft pedal
Sostenuto pedal
Damper pedal
Sostenuto (Center) Pedal......................................................................
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.”
NOTE
• Organ and string voices will continue to sound for as long as the sostenuto pedal is depressed.
Soft (Left) Pedal...............................................................................................
The soft pedal reduces the volume and slightly changes the timbre of
notes played while the pedal is pressed. The soft pedal will not affect
notes which are already playing when it is pressed.
The left pedal can also be assigned to the song start/stop operation
via the “Left Pedal Mode” described on page 26.

Touch Sensitivity
Four different types of keyboard touch sensitivity — HARD, MEDIUM, SOFT
or FIXED — can be selected to match different playing styles and preferences.
TOUCH
HARD
MEDIUM
SOFT
To select a touch sensitivity type press the [TOUCH] button a few
times until the indicator corresponding to the desired type lights (the
indicators light in sequence each time the [TOUCH] button is pressed).
HARD
The HARD setting requires the keys to be played quite hard to
produce maximum loudness.
MEDIUM
The MEDIUM setting produces a fairly “standard” keyboard response.
This is the initial factory default setting.
SOFT
The SOFT setting allows maximum loudness to be produced with
relatively light key pressure.
FIXED (no indicator lit)
All notes are produced at the same volume no matter how hard the
keyboard is played.
When the FIXED type is selected, the volume of notes played in the
FIXED mode can be set by using the [–/NO] and [+/YES] buttons while
the [TOUCH] button is held (the current volume level appears on the
display). The volume range is from 1 through 127. The default setting
is 64.
Transposition
The YDP-121’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 12
semitones (i.e. a maximum of one octave up or down). “Transposing” the pitch of
the YDP-121 keyboard facilitates playing in difficult key signatures, and you can
easily match the pitch of the keyboard to the range of a singer or other instrumentalist.

Tuning
Tuning makes it possible to adjust the pitch of the YDP-121 over a 427.0 Hz
… 453.0 Hz (corresponding to the A3 note’s Hz) range in approximately 0.2
Hertz intervals. Pitch control is useful for tuning the YDP-121 to match other

minute by using the [TEMPO t/s] buttons. The selected tempo will
appear on the LED display while in the normal play mode and while the
[TEMPO t/s] buttons are being used to adjust the tempo in the
recording/playback mode. The default tempo (120 or the recorded song
tempo when the recorder contains data and the playback track indicator
is lit) can be recalled by simultaneously pressing the [t] and [s]
buttons.

Using the Recorder
The YDP-121 features a two-track recorder that let you record what you play
on the keyboard and then play it back. Two tracks mean that you can “overdub”
one part on top of another, using a different voice if you like. The recorder feature
is a useful adjunct to any keyboard study program, since it lets you hear exactly
how you sound from the listener’s perspective. It can also be just plain fun.
The recorder actually records the following data:
■ Entire Song
● T empo ● Time signature (beat) ● Reverb type (including OFF)
■ Individual Tracks
● Notes played ● Voice selection ● V oice variation
● Dual mode voices ● Damper pedal ● Soft pedal
● Sostenuto pedal (not recorded as an initial setting)
● Reverb depth ● Dual balance (F3) ● Dual detune (F3)
● Dual octave shift (F3)

YDP-121
• The track button indicators of tracks which contain previously recorded data
will glow green (unless the track is turned off as described below). The
previously-recorded data on the non-record track will normally be played
back as you record, so you can play along with a previously-recorded track.
If you don’t want to hear the previously recorded track as you record (when
you want to record a song different from what you recorded on the previous
track etc.,), press the playback track button before pressing the [REC]
button (step 1, above) so that its indicator goes out.
• Recording on a track which already contains data will erase all previous
data on that track.
• When the record mode is engaged the amount of memory available for
recording will be shown on the LED display in approximate kilobytes
(starting at “25”), and the rightmost dot on the LED display will flash at the
current METRONOME tempo setting.
