Casio CZ-5000 - PD Sound Source and Waveform Variation; DCA Envelope Generator (Amp Envelope)

_
PD
Sound
Source
and
Waveform
Variation
The
CZ-5000
features
a
PD
sound
source
that
produces
a
variety
of
waves
by
controlling
the
speed
at
which
a
sine
wave
is
read
from
ROM.
(See
User’s
Manual
for
details.)
In
actual
practice,
the
wave
is
altered
over
time
between
the
basic
waveform
and
a
sine
waveform
in
accordance
with
the
envelope
formed
with
the
ECW
envelope
generator.

As
can
be

in
the
figure,
fixing
the
wave
envelope
at
a
constant
level
produces
a
specific
waveform irregardless of time (like an organ).
