Casio CZ-1000 User Manual

The following
is a brief
explanation
of the
various
parts
of Fig.
1.
©Digital
Controlled
Oscillators
(DCO
1,
DCO
2)
The
Digital
Controlled
Oscillators
correspond
to the VCOs
(Voltage
Controlled
Oscillators)
used
in
analog
synthesizers.
As
parameters,
the
DCOs
have Wave
Form
and
Envelope
Generator
parameters. These
parameters
select
the
basic
wave
form
(Wave
Form)
and
control
the
changes
in
pitch
over
time
after
a key has been
pressed.
As
shown in Fig.
a,
you can
choose from
8
kinds
of
basic
wave
forms
(from
SAW-TOOTH
to
RESONANCE)
as
well
as
being
able
to combine
any two*
of these
wave forms
to
create wave
forms such
as
those
shown in Fig.
b.
This
means
that
altogether,
you have
a
selection
of
33
wave
forms to choose
from
according
to the
sound
you want
to create.

Except
the resonance
wave forms
from
6 to
8,
which
cannot be
combined.
The
change
of pitch over time is
controlled by
the envelope
generator.
This
means
that
the
pitch changes
according
to
the rate
(slope)
and level
(final level
in
a step) that have
been
set
for each
step.
