Casio CZ-3000 User Manual

Fig.
1
shows an
example
of an envelope
employing
8 steps.
There are two
attacks
before
the
sustain
point, as well
as
a third attack
after
the key is released,
resulting in
an
"after-
envelope".

Analog
synthesizers
usually
require
the setting
of
envelopes
according
to 4 parameters:
Attack
time,
Decay
time, Sustain level
and Release time
(hence, the name
ADSR
system).
With
the envelope
generator
of the CZ-3000,
only 3 step
settings
are required
to
attain
the same
effect.
BLOCK
CONFIGURATION
The
PD sound
source
of the
CZ-3000
makes it
a
fully
digital
synthesizer.
Actually,
however,
the DCO
(pitch and
basic
waveform
setting),
DCW (timbre
control),
and DCA
(volume
con-
trol)
digital circuits
of the
Parameter
Section
result
in a block
configuration
that
closely
resembles an analog
synthesizer. The
block
configuration
of the CZ-3000
consists of LIME
1
and LIME
2
which
make
up a dual
system.
DETUNE
allows
you to create
differences
between
the
sounds generated
by
LINE 1 and
2
to produce subtle
nuances. With
LIME
SELECT,
a single
line
can be
output
or combined
with
the detuned line
for
a total of 4
line output
settings.

•VIBRATO is the
parameter
that oscillates
the low
frequencies
of
the DCO and applies
a vibrato
effect
Another
parameter
applied to DCO
is
OCTAVE.
DCO
(DIGITAL
CONTROLLED
OSCILLATOR)
DCO
corresponds
to the
VCO
of an analog
synthesizer,
and
is
comprised of WAVE
FORM
for selection of
the basic
waveform
and ENV (pitch
envelope) for
control
of the pitch
over
time for a pressed
key.
The dual
system
line provides
an independent
DCO
1 and DCO
2 which
can be used
as desired.
