GENERATOR
The SH-3
comprises
a
Noise Generator.
Noises
are classified into
two
kinds of
noises which
are alternated
via
the Noise
Changer.
They
are the white
noise audible
as
"Shyaa"and
the pink noise audible
as
"Zaa".
As
these noises emerge
when
depressing
the key, they
may
be used together with
the
sound coming from
the
VCO.
The
sound of
a
steam locomotive "SL"
and
the
sound
of the wind
or waves can
also
be produced by
using these noises alone.
When
switched
to
"TO
VCF",
noise
mode
can
be
changed
via
the
VCF,
and
when
switched to
"TO VCA",
white
or pink
noise
can be
directly produced
at
VCA.
Output
can
be adjusted
by
setting the
LEVEL
dial.
