SOUND
CREATION I/VCO
THE
VCO
BLOCK
The
VCO
(Voltage Controlled Oscillator)
is
the basic
sound
source of
the CS01 producing
a signal at
the
pitch
determined by
the
keyboard.
RANGE
SELECTION
O
FEET SELECTOR
This
selector
determines the range
of the
CS01 keyboard. The
CSOI's 32-key keyboard
covers
a
range of 2-1/2 octave (F2--C5
when
the
FEET
selector
is
set to 8).
The
FEET
selector permits
shifting the
keyboard
range over
a five
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.

the

have
different types (odd or even) and
different

of harmonics, and
therefore different sounds.
