NOISE
GENERATOR
The
NOISE
GENERATOR
is
used
as
the
sound source
for effect
sounds
like
wind,
surf,
and thunder.
Two
types of noise
are available:
white
noise
and
pink
noise.
White
noise
is
the
random
combination
of
all
frequencies, This
kind of noise
is
like
the
hissing
sound which
can be heard
when
an
FM
tuner
is
set at
a
point
where
there
is
no
station broadcasting.
Pink
noise
is
similar,
but has
some
of the higher
frequencies
filtered
out
to
produce
a
sound
more
like
a
waterfall.
The random
notes of the
MOD
(Modulator)
are
due
to
irregularly
changing
voltages
produced by sampling the noise wave.
AUDIO MIXER
This mixer mixes outputs of the
VCO,
Sub-osciHator, Noise Generator,
and
the
external input
signal.
The
OVERLOAD
indicator
lights
when
the
external
level
is
excessively
high.
The
indicator
is
not related to the position of
EXT
SIG
slider.
Keep
the externa! signal
level
so that
the overload indicator goes
on
at
the
peak volume.
