Casio CZ-1 User Manual

Etiiliii
The CZ-1 features a
dual system
DCO/DCW/DCA,
and each system
has its own
independent
envelope
generator
for
control of changes in
notes, timbres and
volume over time.
The envelope
generators
can
set up
to eight
steps
including
setting of the sustain point (the level at which a note
is sustained while
a
key is
depressed).
This
provides
greater versatility than
the
conventional
ADSR
generator
and makes
sound creation
possibilities
virtually
unlimited.

*Ri
through
Rg indicate
the
RATE (slope)
of
each vari-
ous step, while
Li
through
La
indicate the LEVEL
(des-
tination
level).
Li
is
reached
at a
slope
of
Ri
in STEP
1,
L2
is reached
at a
slope
of R2 in
STEP
2,
etc.
Fig.

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,
result-
ing in
an '*after-envelope".

Point
Analog
synthesizers
usually
require
the
setting
of
enve-
lopes 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-1,
only
3
step settings
are
required
to
attain
the
same effect.
