Kevboards
This Electone has three keyboards. They have keys and octaves as follows:
Upper Keyboard 44 keys (3-2/3 octaves)
Lower Keyboard 44 keys (3-2/3 octaves)
Pedals 13 keys (1 octave)
This Electone is designed to permit playing the melody on the upper keyboard with the right hand, the
chords on the lower keyboard with the left hand, and bass note on the pedals with the left foot.
All keys are arranged in the keyboard method layout shown below, Each white key has a name (from C
to B), and the blacks are sharps or flats,

Note:
It should be noted that precedence is to the higher nota if two or more keys are
pressad simultaneously. This assures tonal clarity
Tone Levers
a
To the left of the upper and lower keyboards are series of
tone levers which control the Electone voices which will
sound when the keys are depressed. They are divided into
groups for upper, lower and pedals, so that different regis-
trations can be set for each.
Upper Keyboard Levers 8 voices
Lower Keyboard Levers 5 voices
Pedal Levers 2 voices
PITCHES OR FOOTAGES
The B-20CR has four different pitch levels, indicated by
the numbers 16’, 8’, 4’ and 2%’. 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 will provide a tone exactly one octave lower than
the written note.
Similarly, 4° tones are one octave higher than the written
note, 254" tones are one octave and a fifth higher than the 8’
fundamental.
Preset Tones
To the left of the lower keyboard 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 (Ac-
cordion, Piano, Hawaiian Guitar, Banjo) as well as three special preset combinations.
Since these buttons are factory preset, they automatically cancel all other upper keyboard 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.
"E
{>
Vibrato
Vibrato is a waving of the tone. You will see violin and cello players use it freely by an oscillating
motion of the left hand. That increases the emotional quality of the violin tone. This vibrato lever
produces the same vibrato effect.
Brilliance
With this single, continuously-variable control you can pinpoint the degree of overall softness or clarity
desired for any mood of music.
Upper Percussive
Changing the beginning of some or all notes can do wonders for lively selections. Your B-20CR's per-
cussive effects provide subtle but important shading at the moment each note is heard. The special
popping 4,2 % percussive drive can be smoothly blended into all upper keyboard tones with percussive,
4,2%, and a percussive length lever regulates the length of decay for this effect.
With percussive, use a detached 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.
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. Affect upper keyboard notes
only.
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
Coe affected. The length of such sustain is set by the Upper
\ Sustain control. When combined with Upper Percussive 4’,
all sound is cancelled.
N. KNEE LEVER
N 7 This lever is operated with the right knee for instantaneous
a 7 implementation or stop of the sustain effect preset by the
sustain control and selector, allowing passage-by-passage or
even phrase-by-phrase sustain control precision.
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.

Tremolo/Chorus
TREMOLO SPEED
à
The Electone’s special tremolo is produced by a Rotary
speaker that actually spins just behind the Rotary speaker
grille on the side of the cabinet.
The tremolo selector is complemented by a continuous
tremolo speed control knob.
When the speed control is set to its maximum position,
the Tremolo will turn the speaker at normal revolution.
The Chorus will turn it at one revolution. Once either tablet
ts switched on, it takes several seconds for the rotary speaker
TREMOLO
. —— 7— to attain the standard speed. This is also true when switching
MAIN to a slower speed (Tremolo to Chorus), the speed variation
will be heard in the music.

If you wish an instant tremolo or chorus sound, be sure to
switch on that tablet well in advance of the speaker selector.

Pedal Sustain
This control provides continuous adjustment of the sustain effect on the pedals and allows the pedal
note to continue to sound a few seconds after you have released it.
Manual Balance
This control governs the volume strength of the upper and lower keyboards. 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 keyboards.
Expression Pedal
Affect the emotional mood of every passage by letting you vary the volume continuously with your right
foot. This works within the range set by the master volume control.
Master Volume
Determines the maximum volume obtainable by depressing the expression pedal.

Auto Rhythm Section
This section provides eight catchy rhythms, each one called forth by a simple button. You can also
enjoy more rhythm variations with the variation button. In addition to a combined volume and balance
knob, tempo control and tempo indicator 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 keyboard or pedal note is struck. À foot switch fitted in the expression pedal housing lets
you stop and restart the rhythm at any point during play, when the rhythm stop control is on.
NORMAL 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 tempo established. The rhythm
will begin as soon as you strike a lower keyboard 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 FOOT SWITCH
Once the rhythm is on, push this switch once to instantly
stop it, once again to restart,. lt lets you stop and restart
the rhythm in the middle of a selection without using
your hand.
Note: If the foot switch has been used, be sure it is reset to normal
after you finish playing your selection, and then make sure
both Start and Synchro-Start switches are off. Otherwise
you may turn on one of the switches in the middle of a new
number only to find the rhythm still cancelled.
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 keyboards. 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) accord-
ing to your taste and the selection. It can make a big
difference 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.

Electone is not out of order If...
a
to... the set does not go on when the power switch is
turned on. Check the following.
Is the AC plug fully inserted into the electric wall outlet?
Reinsert it to be sure. Is there power coming from that
outlet?
If there is power in the outlet but the Electone does not
play, unplug the cord and contact your Yamaha dealer.
There are NO USER SERVICEABLE PARTS inside.
2. ..... a sound should occur the instant you turn on the
switch. |
This merely indicates normal operation consequent on a
surge of electricity in the main amplifier.
x occasional unpleasant static occurs.
In the majority of such cases, the cause can be traced to
the turning on or off of refrigerators, washing machines,
electric pumps or other household appliances. Electrical
faults in a neighboring outdoor neon sign may also be to
blame.
If the cause is a fault in a neon or fluorescent lighting
fixture, it should be repaired. When the cause is un-
known, or in case of doubt, contact your Yamaha dealer.
ED
4. ..... the Electone reproduces radio or TV signals.
If there is a powerful transmitter such as a radio station
in the vicinity this can occur. Contact your Yamaha
dealer.
D. ..... pedal notes sound too high, upper keyboard's notes
too low. This is especially noticeable when comparing
the Electone with piano. Piano tones are combinations of
harmonics and must interact with their surroundings,
while Electone harmonics are simpler {multiples of the
fundamental tone), requiring the Electone to be adjusted
differently at the assembly stages.
Ces rattling (sympathetic vibration) occurs.
All materials have critical resonance frequencies at
which they vibrate. The Electone’s continuous tones
will naturally cause other objects (windows, shelves, etc.)
to vibrate.
