The DK-40B has five keyboards. The upper four are called “manuals” (“solo”, ‘‘portamento”,
"upper" and “‘lower’’), and the bottom, for the feet, is the. "pedals."

The Electone is designed to permit playing the melody on the upper manual with one hand, the
chords on the lower manual with the other, and bass notes on the pedals with either foot. For special
selections the solo manual can be used to provide a melodic line with its own exciting voices. Use
the portamento manual to create a range of unique sounds, pressing or sliding your finger(s) up and
down. All keys and pedals are arranged in the traditional keyboard method: two black keys, three
black keys. Each white key has a name (from C to B), and the blacks are sharps or flats. “Cis
always the white key just below the left black key in the two-black-key group. Any complete set
of seven white keys and five black keys is called an “octave”.

All four Solo voices have been specially designed for brilliant realism. Each voice is set via its selector
tablet at the left of the Solo manual.
Note: The four voice tabs, i.e., Violin, Clarinet, Trumpet and Saxophone, control voices which purposely cannot
produce chords; if two or more keys are pressed simultaneously, only the higher will sound. Please also
note that solo voices cannot be combined. If two or more voice selector tabs are pressed, the one to the
the right takes precedence.
TOUCH VIBRATO
This world-famous Yamaha exclusive gives to the organist
the same expressive fingertip vibrato enjoyed by the violinist.
With this effect, vibrato can be applied to any solo note
by the lateral vibration of the hand, and its speed will
correspond exactly to the hand's vibration.
FUZZ
Fuzz is frequently used on the electric guitar.
This Fuzz effect affects each tone of the Solo manual by
switching the Fuzz selector “ON.”

The Portamento manual produces continuous pitch shifts
just like those produced when the finger slides up and
down a violin string. The 2% octave range becomes higher
toward the right. There are four Portamento voice selector
tabs and except for the Astro tab they can all be combined
with each other. If the Astro tab is set it cancels all the
others.
PORTAMENTO VOLUME CONTROL
This permits a separate volume control.
On the panel above the solo manual and selectors is a
series of tone levers which control the voices (instrument
sounds) which will be heard when the keys are depressed,
as well as many of the effects. They are divided into groups
for upper, lower and pedals, so that different registrations
can be set for each.
Upper Manual Levers 12 voices
Lower Manual Levers 5 voices
Pedal Levers 3 voices
PITCHES OR FOOTAGES
The DK-40B has five different pitch levels, indicated by
the numbers 16’, 8’, 5%’, 4’ and 22", These are standard
musical abbreviations showing the tone’s pitch in relation
to the fundamental (written note). An 8’ tone will sound
just as it has been written. As the numbers increase, the
tones lower. A 16’ tone (meaning that the wave length of
the vibrations are twice as long as 8’, or half as fast) will
provide a tone exactly one octave lower than the written
note. Similarly, 5%’ tones are a fifth higher than the written
note, 4’ tones one octave higher, and 2*5' tones one octave
and a fifth above the fundamental. Tones at octave intervals
from the written notes are "consonant harmonics," while
all others are ‘‘dissonant.”

Upper Preset Tones
To the left of the lower manual are eight Upper Preset Tone selectors (seven tones plus Cancel).
These on/off switches are special tonal blends that most closely resemble the instruments they name
(Accordion, Piano, Hawaiian Guitar, Banjo) as well as three special preset combinations.
Since these buttons are factory preset, they automatically cancel! all other upper manual tone lever
settings. This lets you switch back and forth. In addition, precedence is to the right. This means
that if two or more buttons are pressed, the one to the right will take effect. To switch from one
button to another it is not necessary to first press the cancel button.
Note: Upper Sustain control lever does not work with the Accordion, Piano, Hawaiian Guitar and Banjo preset
selectors.
ORGAN PRESET ENSEMBLE
This lever controls the effect which adds the upper tone to the upper preset tone. (Accordion, Piano,
Hawaiian Guitar, Banjo)

Effect Control Levers different effects which and a variety of total variations to the Electone’s voices.
Each lever works in the same way as the tone levers, with both infinitely-variable continuous control
and click-stop settings.
Brilliance
With this single, continuously-variable control you can
pinpoint the degree of overall softness or clarity desired
for any mood of music.
Vibrato,
Vibrato
Speed
Vibrato is an emotional wavering applied to a tone most
noticeable in the trembling left hand of violinists and
cellists. It can add a great deal to the emotional depth
of a passage, especially string voices. The Vibrato lever
provides continuous adjustment of this effect’s depth, while
Vibrato Speed lets you continuously set the vibration speed.
Repeat Speed
Cuts and repeats each note just like the double-strumming
effect of a mandolin. The lever provides continuous speed
adjustment to create a full variety of different moods.
Affects upper manual notes only.
Upper Percussive
Changing the beginning of some or all notes can do wonders
for lively selections. Your Electone’s percussive effects
provide subtle but important shading at the moment each
note is heard. The special popping 4’ and 224" percussive
drive can be smoothly blended into all upper manual tones
with two variable levers, and a separate lever regulates the
length of decay for this effect. With percussive, use a
staccato fingering. Each note should be played cleanly;
slurred notes will diminish the percussive impact.
Note: If Upper Percussive 4’ is set at the same time as Upper
Sustain, no sound will be heard.
Percussion
O BRUSH LOWER CYMBAL, PEDAL CYMBAL
Provide lively brush (hissing snare drum brush) and cymbal
percussion sounds with each lower manual or pedal note.

Provides a spicy wah-wah sound at the beginning of every
upper manual tone.

Reverb
The reverberation effect, which makes your playing sound
full and rich, as if you were playing in a large hall, can
be adjusted continuously and smoothly to suit your taste.
Sustain
UPPER, PEDAL SUSTAIN
These controls provide continuous adjustment of the sus-
tain effect on the upper manual and pedals concerned.
For the pedals, this is the only sustain control, and it affects
all pedal tones with the exception of Bass Guitar, while
for
the
upper
manual
this
control
is
only
a
length
adjust-
ment. Length of upper sustain is controlled by the upper
sustain control knob as explained below.
Upper 8’, 4° Sustain
When this is switched on, the sustain effect is evoked.
As the name of the tab implies, only 8' and 4’ tones are
affected. The length of such sustain is set by the Upper
Sustain control. When combined with Upper Percussive 4',
all sound is cancelled.
Manual Balance
This control governs the relative strength of the upper and
lower manuals. It is normally left in the center position,
but can be shifted to stress the melody or accompaniment
in a selection or passage.
This control can also be used to compensate for a higher
number of total tone lever settings (which would ordinarily
result in higher volume) on one of the two manuals.
Upper 8',4' Attack
This tab provides an effective rhythmical element, much
like that of a string bass played pizzicato. It is particularly
impressive
in
rhythmic
works,
and
give
greater
definition
to the beginning and end of notes. The 8', 4' Attack
tab affects all upper manual 8' and 4' voices.
Glide (FOOT SWITCH SELECTORS)
While the foot switch is pushed when the Glide selector
is on, tones will be lowered one half octave.
Expression Pedal
Affects the emotional mood of every passage by letting
you vary the volume continuously with your right foot.
Works within the range set by the master volume control.

Auto Rhythm Section

SYNCHRO-ST
This section provides 14 catchy rhythms, each one pro-
duced by a simple button. In addition to a combined
volume and balance knob, tempo control and tempo indi-
cator light, there are two other switches: ordinary Start
and the Yamaha Synchro-Start which begins the rhythm
accompaniment on the first beat of a measure, when the
first lower manual or pedal note is struck. The special
expression pedal foot switch lets you cut and restart the
rhythm at any point during play.
RHYTHM START
For instant rhythm at the beginning of a selection. Push
the rhythm selector desired, then flick the Start switch on.
SYNCHRO-START
Select the rhythm, switch on the Synchro-Start and begin
to play once you have the beat established. The rhythm
will begin as soon as you strike a lower manual or pedal
note. This switch permits you to lead in with a rhythm-
free melody at first if so desired.
You can switch off the Auto Rhythm with the foot switch.
When you wish to continue hearing the Auto Rhythm,
be sure to switch on with the foot switch.

RHYTHM STOP (FOOT SWITCH SELECTORS)
This tab activates a click-switch located at the left side
of the expression pedal. When the tab is on and the rhythm
section operating, touch the foot switch once and the
rhythm automatically stops. Touch it again to switch back
on.
Note: The tab controls the foot switch. If the rhythm has been
cut by the switch and one of the rhythm start switches is
still on, cancelling the tab will erase the effect of the foot
switch - - in other words, the rhythm will go back on again.
TEMPO
The tempo of the Auto Rhythm section can be adjusted
by a continuous control knob. This is best accomplished
by turning on the Synchro-Start switch.
Although no sound will be produced, the indicator lamp
will flash each quarter note, letting you visually check the
tempo while you adjust.
VOLUME
Use it to balance the volume of the rhythm section and
the manuals. This volume is then varied during the selec-
tion by the expression pedal, just like that of the other
tones.
BALANCE
This control lets you balance the low rhythm sounds, such
as drums, and the high sounds (i.e,, cymbals) according
to your mood and the selection. It can make a big differ-
ence even when using the same rhythm. Turn the knob
to the right to accentuate the higher (treble) sounds, to
the left for lower (bass). If you accentuate the treble
sounds the rhythm becomes brighter. Check the playing
hints for specific settings.

Auto Bass/Chord Section
This section is comprised of the Auto Bass/Chord lever
and Bass Variation selectors, all located at the far left of
the lower manual. It works in conjunction with the rhythm
selector buttons of the Auto Rhythm section.
If you play a lower manual chord without the Auto Bass/
Chord lever on, it will sound in the ordinary way, with
all notes beginning when pressed, and ending when released.
By sliding down the Auto Bass/Chord lever, however, an
automatic memory system couples the rhythm section to
the lower manual keys and pedals so that the pressed chord
will be played one note at a time according to the selected
rhythm and bass variation. This rhythm pattern will con-
tinue as long as the chord is held down, and fingering is
not necessary.
First select the rhythm desired, and set the speed. Switch
on the Auto-Rhythm Synchro-Start switch, and turn the
Auto Rhythm Volume knob all the way to the left (off).
Pull the Auto Bass/Chord Lever forward (on).
Set the Sustain, Bass 16’, Bass 8’ and Bass Guitar levers
to the desired positions.
Push one of the Bass Variation buttons.
Note: When the Auto Bass/Chord is on, the rhythm sounds of
the Lower Manual are limited to Horn 8’, Cello 8’ and
Cello 4'. In other words, these are the only Auto Bass/Chord
sounds obtainable.
Now, as soon as a lower manual chord (major, minor,
seventh or minor seventh) as pressed, the rhythm will go
on, but instead of rhythm instrument sounds the rhythm
will be played as a variation upon the pressed chord.

After you have mastered this simplest use of the Auto
Bass/Chord system, you can vary the effect by choosing
between the three Bass Variation selector buttons.
It is also possible to combine the Auto-Rhythm sounds
with the Auto Bass/Chord accompaniment; simply turn up
the rhythm volume.
By using the ordinary Start switch instead of Synchro-
Start, the combined rhythm sounds will play before and
after the chord is pressed.
This is the basic pattern; it alternates the root (1) and fifth
(5) in the bass regardless of rhythm chosen or type of
chord. The one exception is the Jazz Rock rhythm, which
maintains root (1) pedal and no alternation.
Note: The Slow Rock and Jazz Rock rhythms play only the root
(1), when the Rhythm Variation is switched on.
This selector effects the Slow Rock and Rhumba rhythms,
with which it will play a root (1), third (3), and fifth
(5) pattern. All other rhythms function as with the (1-5)
selector.
Note: The Rhumba rhythm will play a root (1), third (3), and
fifth (5) pattern, when the Rhythm Variation is switched on.
17.5
This selector effects the Slow Rock and Rhumba rhythms
when a seventh or minor seventh chord is being played,
with which you will hear the root (1), seventh (7), and
fifth (5) bass notes. When playing a major or minor
chord the unit will perform exactly as it does with the
second Bass Variation selector (1-3-5).
Note: The Rhumba rhythm will play a root (1), seventh (7), and
fifth (b) pattern, when the Rhythm Variation is switched on.

Besides the many tone and effect controls through which almost infinite varieties of voice and
expression can be obtained the Yamaha Electone DK-40B offers you a number of additional features
to further enhance your playing pleasure.
HEADPHONE
A Yamaha headphone set (optional) can be plugged into the jack under the keyboard. With the
headphone connected, the speaker is automatically shut off, allowing you to play or practice at any
volume level without disturbing anyone.
MONAURAL
EXTERNAL JACK This jack can be used for input.
Also, you can feed any sound source into this jack to play
that sound (tape recorder, etc.) through the Electone
speaker. During input, the signal coming in is not affected
© (eo by the expression pedal, so you can play along on the
Electone in the normal manner.
TONE CABINET SOCKETS This socket is on the rear panel. Use it to connect a
Yamaha Tone Cabinet, without any rewiring required.

. Only one note sounds two keys are pressed simultaneously.
The electone is designed to play only one note if two or more are pressed at the same time. Only
the higher note will sound. This assures tonal clarity.
. Occasional static occurs.
This is usually caused when other household appliances (refrigerator, etc.) switch on or off. A
defective neon sign in the neighborhood can also be to blame. If the cause is a home appliance,
plug the Electone into an outlet as far as possible from that appliance. Such static will not damage
the Electone circuitry. If the cause is a neon sign or fluorescent light, the unit should be repaired.
If you have questions, contact your Yamaha dealer.
. The Electone reproduces radio or TV signals.
If there is a powerful transmitter such as radio station in the vicinity this can occur. Contact
your Yamaha dealer.
. Rattling (sympathetic vibration) occurs.
All materials have critical resonance frequencies at which they vibrato. The Electone's continuous
tones will naturally cause other objects (windows, shelves, etc.) to vibrate.
. Pedal notes sound too high, upper manual notes too low. This is especially noitceable when
comparing the Electone and piano. Piano tones are combinations of harmonics and must interac
with their surroundings, while Electone harmonics are simpler (multiples of the fundamenta! tone),
requiring the Electone to be tuned differently.
. If Upper 8’, 4’ Attack is set at the same time as Upper Sustain, no sound will be heard.
