A
New
Sound
in
the
World
of
Music
Yamaha is continually striving for
the production of sound which is
“lively” and “rich”. The CSY-2A
has thus been hailed as a great suc-
cess — it features a new “live sound”.
Furthermore, it incorporates func-
tions by which this sound can be
freely varied. The synthesizer func-
tion is a new addition, bringing an
even wider range of music to the
fingertips of the performer.

3] Circuit which varies the
4 of tone volume and tone color:
In the synthesizer section of the CSY-2A, all basic tones are
pre-set to solve complex operational problems which often
hamper the effectiveness of synthesizers. A system which
allows freedom of variation in tone color, intervals, pre-set
tone volume, and the creation of new sounds is built into the
synthesizer section of the CSY-2A.
The synthesizer is a system to control the oscillator which
generates tones, a filter which affects tone color and an am-
plifier which amplifies tones by voltage. Thanks to the syn-
thesizer, we can now control tone color according to time,
control the starting and damping of tones, and freely vary
intervals. |
As for the tones of natural instruments such as the trumpet,
violin, etc. which we hear all the time without paying much
attention to, at the points of the tones’ beginning, continua-
tion, and decay, the color, interval and volume are subtly
changing. The time required for these changes is not the same
for all instruments, and this time plays an important part in
forming the tone color of each instrument. Therefore, with
the use of the synthesizer tones extremely close to the natu-
ral tones can be created, while in addition completely new
musical sounds can also be created.
To briefly describe the principle of this synthesizer, there is a
voltage-controlled oscillator (VCO), a voltage-controlled filter
(VCF) and a voltage-controlled amplifier (VCA), which are
linked as shown in the diagram below. When a key is pressed,
a certain voltage is generated which affects the VCO to deter-
mine the interval. The signal passed through the VCO enters
the VCF, where tone color is determined. The spacing of the
tone color changes is controlled by signals from another
circuit (the envelope generator). Finally, amplification is
carried out in the VCA. Start, decay and length of sustain are
also determined, and the sound is emitted. Sounds produced
in this way have a natural and vivid feel.

Kevboards
The CSY-2A has three keyboards. The upper two are called “manuals” and the lower one, played with
the feet, “pedals.” They have keys and octaves as follows:
Upper Manual 44 keys (3% octaves)
Lower Manual 44 keys (3% octaves)
Pedals 13 keys (1 octave)
The CSY-2A is designed to permit playing the melody on the upper manual with the right hand, the
chords on the lower manual with the left hand, and bass notes 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.

Selectors
You can play synthesizer voices on either the upper manual or the pedals. Many combinations can be
made by combining the positions of the three levers at the right of the panel
and Synthesizer Selector levers.

Preset Tone
Your CSY-2A has 14 preset tone levers on the front panel.
When you depress one of the levers and push a note, you
hear the sound of the instrument voice identified by name
on the lever panel. It is designed to create the sound of
only one instrument at a time.
Note: If you depress more than one preset tone lever at the same
time, you hear only the instrument selected by the lever
furthest to the right on the panel. When no levers are de-
pressed, you hear no synthesized voices.
Tuning
To tune the synthesizer section of the CSY-2A with the
Electone or another instrument, wait about fifteen min-
utes after it is turned on. Then push down the Flute preset
and the vibrato lever to the “control” position, and slide
the vibrato depth control to the “minimum” position to
eliminate the vibrato. Slide the “tuning control” (at the
extreme left of the panel) to the left (flat) or right (sharp)
until you obtain the right pitch; the pitch can be increased
or lowered about 100 cents (one semitone) in relation to
the standard pitch. To easily obtain proper pitch, match
the Flute preset with the 8° Flute tone lever on the
Electone portion of the CSY-2A.
Transposition
On the front panel, to the right of the preset tones, there
are four transposition levers. These levers shift the syn-
thesized voices up one or two octaves, or down one octave.
When you depress two or more transposition levers at the
same time, you hear only the one furthest to the right on
the panel. When no transposition lever is depressed, you
hear the keyboard as if the “normal” transposition lever
was depressed.
The synthesizer section of the CSY-2A is designed to sound
one note at a time; if you depress more than one key at
the same time, you will always hear the highest note.
The volume of the synthesized voices is affected by the
expression pedal.
Filter
Simply stated, a filter alters the harmonics contained in a
note to change its color or timbre. Each of the preset
tones has as a design feature the characteristic harmonic
structure and resonant points that identify a particular
instrument. Switch the filter to manual control by putting
the filter lever in the “control” position (down).
You can now control the filter characteristics (from low-
pass to highpass, and degree of resonance) with the cutoff
frequency and resonance controls.
