When you intend to run the CS01 on batteries, make sure the optional
PA-1 AC adaptor is unplugged from theCSOl external power jack. The
batteries are automatically disconnected when the PA-1 is plugged into
the CS01 power jack.
BATTERY LIFE
Battery life depends to some degree on the type of batteries used and
volume level, but generally, 6hours of continuous use can be expected
when using the built-in amp and speaker at maximum volume. Battery
life is approximately 16 hours when using an external amplifier.
BATTERY REPLACEMENT
The CS01 features abuilt-in low-battery warning circuit. When battery
voltage drops below the usable level, the CS01 power indicator LED
will flash on and off. When this occurs, all the batteries should be
replaced before battery operation is continued.

*Be sure to replace all batteries with new ones at one time. Used
batteries and new batteries must not be mixed.
*If batteries are not to be used for an extended period of time, they
should be removed from the battery compartment to prevent
damage due to battery leakage.
OAC ADAPTOR
The optional PA-1 AC adaptor plugs into the CS01 DC IN 12V jack.
Side panel
The batteries are disconnected when the PA-1 is in use, so no battery
discharge will occur.
Using AC adaptors other than the PA-1 may result in damage to the
CS01 due to incorrect polarity. „
Polarity is reversed in some adaptors

CONNECTING TO AN EXTERNAL AMP
When using the CS01 with headphones or an external amplifier rather
than the built-in amplifier and speaker, connections must be made via
the CS01 side panel.
When aplug is inserted into either the PHONES or LINE OUT jack, the
internal speaker is automatically shut off.
OPHONES (HEADPHONE JACK)
This jack accepts either apair of monaural keyboard monitor head-
phones or any standard pair of stereo headphones (output is
monaural).
©LINE OUT
Provides output to an external amplifier or mixer. This output jack
cannot be connected directly to an external speaker. Amusic
instrument amplifier or audio amplifier must be used.

BASIC SETTING
TURNING THE INSTRUMENT ON
POWER/VOLUME
This control serves the dual function of power switch and volume
control. If rotated clockwise the unit is turned ON and the indicator
LED will light. Volume increases as the control is rotated towards
the "10" end of its scale.
The CS01 is amonophonic synthesizer (high-note priority). If more
than one key is pressed at atime, only the sound of the highest note
played will be heard.
OTurn the power ON, and set the CS01 controls as shown in the
illustration. You should now be able to hear notes played via the
CS01 's speaker.

SOUND CREATION I/VCO
THE VCO BLOCK
The VCO (Voltage Controlled Oscillator) is the basic sound source of
the CS01 producing asignal at the pitch determined by the keyboard.
RANGE SELECTION
OFEET SELECTOR
This selector determines the range of the CS01 keyboard. The
CSOI's 32-key keyboard covers arange of 2-1/2 octave (F2--C5
when the FEET selector is set to 8). The FEET selector permits
shifting the keyboard range over afive octave range.
If this selector is set to WN, white noise is produced. By applying
filtration to this white noise using the CS01 VCF, the sound of surf,
wind or waves can be created.
Try switching the FEET selector through its settings while playing a
note on the keyboard.

SOUND CREATION U/VCF
The CS01 offers four different waveforms plus apulse width modula-
tion feature as shown in the chart below.
Waveform Name Characteristics
ATriangular wave Subdued tone. Ideal for flute sounds.
r\ Sawtooth wave Bright tone. Perfect for violin and
other string sounds or brass instru-
ment sounds.
ru Square wave "Woody" tone. Great for clarinet.
ru Rectangular
wave Vibrant tone. Trumpet, oboe, etc.
ru PWM Thick, rich sound. Chorus effect.
The PWM SPEED ©and GLISSANDO ©controls will be described
in Sound Creation V/Other Functions.
All the controls described so far determine the basic CS01 sound. In
order to fully understand the operation of the VCF (described next),
return the controls to their Basic Settings (refer to the illustration on
the previous page).
VCF BLOCK
The VCF (Voltage Controlled Filter) alters the tonality of sounds
created by the VCO by cutting off certain harmonics.
CREATING THE DESIRED TONALITY
FREQ. CUT OFF LEVER
Determines the cut off frequency of the VCF.
Level Basic sound with harmonics
Cutoff point —
-
Setting this control at the "H" end of its scale permits all the upper
harmonics of the basic sound to pass, thereby creating abright tonality.
Moving the control towards the "L" end of the scale gradually cuts off
more and more upper harmonics, creating arounder, softer tonality. If
the FREQ. CUT OFF lever is set all the way to "L", the fundamental
may be cut off and no sound will be heard.

©RESONANCE SELECTOR

SOUND CREATION IV/EG
EG BLOCK
The EG block contains the CS01 envelope generator controls. The
sound of an instrument is largely determined by its pitch, tone, volume
and envelope. Piano and flute sounds, for example, consist of basically
the same waveform, but have completely different level envelopes. A
flute sound builds up arelatively slow attack and continues at a
sustained level, while apiano note begins rapidly (fast attack) and then
decays gradually.
The CS01 EG block lets you create an exceptionally broad range of
level envelopes.
©ATTACK TIME LEVER
Determines how long it takes for the sound to reach maximum level
after anote is played on the keyboard. The more this control is set
towards the "L" end of its scale, the longer the attack.
<D DECAY TIME LEVER
Determines how long it takes for the sound to decrease to sustain
level after maximum attack level has been reached. The more this
control is set to the "L" end of its scale, the longer the decay.
If the SUSTAIN LEVEL control (described next) is set to maximum,
no decay effect will be produced.
SUSTAIN LEVEL LEVER
Determines the continuous level to be maintained after attack and
decay are finished, as long as akey is held. The more this control is
set towards the "10" end of its scale, the higher the sustain level.
When applied to the VCF, the sustain level determines the VCF cut
off point.

Determines how long it takes for the sound to completely fade out
after akey has been released. The more this control is set towards
the "L" end of its scale, the longer the release.

MODULATION
Modulation means to apply some form of periodic variation to asound.
The CS01 permits modulation via PWM (Pulse Width Modulation) and
an LFO (Low Frequency Oscillator).
PWM (PULSE WIDTH MODULATION)
This function periodically varies the width of each pulse in each cycle
of arectangular wave at aspeed determined by the setting of the PWM
SPEED control .This function can be used to create avariety of
chorus-like effects.

LFO (LOW FREQUENCY OSCILLATOR)
The LFO can be used to modulate the VCO or VCF to create periodic
variations in pitch or tonality.
©LFO SPEED LEVER
Determines the frequency of the LFO. The more this control is set
towards the "F" end of its scale, the faster the LFO speed.
<D MODULATION WHEEL
Determines the degree of modulation applied to either the VCO or
VCF. No modulation is applied when this wheel is set at "0". Roll-
ing the wheel upward causes increasing modulation depth.
®VCO/VCF SELECTOR
Determines whether modulation is applied to the VCO or VCF.
Applying modulation to the VCO creates vibrato-like effects, while
modulation the VCF can create wah-wah, growl, and an extensive
variety of other effects.
Applying modulation to the VCF produces aperiodic shift in the
VCF cutoff frequency. If the FREQ. CUT OFF ©or EG DEPTH©
controls are set too high, VCF modulation may, not be effective.
PITCH VARIATION
©PITCH BEND WHEEL
This control can be used to create sudden pitch variations as you
play. This permits creation of effects similar to choking aguitar
string. Pitch can be varied over approximately one octave.
©GLISSANDO LEVER
Creates astep-wise (1/2-tone steps) glissando between notes played.
Set towards the "L" end of its scale this control produces aslow,
fowing glissando, while set towards the "S" end of the scale amore
continuous portamento-like slide is produced.
13

Try pressing alow note on the keyboard and then, still holding the
low note, play ahigh note. Astep-wise glissando will run from the
lower note to the higher note. Now release the high note and the
sound will glissando down to the low note.
The glissando effect normally only functions while akey (or keys) is
held. If the EG block RELEASE TIME <B control is set to along
release time, glissando will function during the release of anote.
BREATH CONTROL
By connecting the optional Breath Controller unit (BC1) to theCSOl,
you can control the VCF and VCA according to how hard you blow
into the Breath Controller mouthpiece. By permitting wind-instrument
type tounging, etc., this function makes it possible to create effects not
possible with any other electronic instrument.
©BREATH CONTROL JACK
The optional BC1 Breath Controller is connected here. VVhen
connecting the Breath Controller, be sure to turn the CS01 volume
control all the way down.
