DLFO
(Digital
Low
Frequency
Oscillator)
—
A
Circuit
that
corresponds
to
the
LFO
(Low
Frequency
Oscillator)
of
an
analog
synthesizer,
and
generates
low
frequency
waves
for
vibrato
effects.
This
shows
how
easy
it
is
to
view
the
various
blocks
of
the
CZ-5000
along
the
lines
of
analog
synthesizers,
meaning
that
it
is
possible
to
create
totally
new
sounds
without
having
to
learn
any
new
kind
of
synthesis.
Note
that
the
CZ-5000
offers
a
dual
line
systems
consisting
of
the
blocks
shown
above,
resulting
in
the
block
structure
shown
below.

The

in
units
of
one

one

1/60

also

Note

the

it

polyphonic.
The
Detune

Line
Select
functions
fet
you
create
a
variety
of
effects
by
combining
the
different
sounds
on
each
line
or
detuned
and
normal-pitch
tones
for
a
fatter,
spacier
sound,
or
to
obtain
various
naunces.
For
example,
by
combining
a
normal-pitch
string
tone
with
a
slightly
detuned
string
tone,
you
can
achieve
an
even
more
realistic
sound.
Another
interesting
example
is
the
combination
of
an
organ
tone
with
key
click
noise
for
a
funky
jazz
organ
sound.
