VCFA/CA
SAW
Sawtooth
wave
(a
bright
sound
used
in
creating
strings
and
brass
patches).
PULSE
The
audible
characteristics
of
a
PULSE
wave
are
described
above
in
the
paragraph
on
PWin
Page
1.
NOISE
The
NOISE
generator
produces
a
pitchless
"rushing"
sound
(VCO
2
only)
suitable
for
wind
and
thunder
effects
as
well
as
adding
breath
inflections
to
flute,
brass
and
woodwind
sounds.
The
VCFA/CA
section
of
the
MATRIX-12
is
where
the
sound
generated
by
the
VCOs
is
"tailored"
by
you
to
determine
what
the
patch
will
finally
sound
like.
This
section
performs
important
functions
such
as
controlling
the
harmonics
(the
overall
brightness)
of
the
sound
and
adding
dynamics
to
the
Patch.
VCF
stands
for
"Voltage
Controlled
Filter"
and
is
the
circuit
that
gives
you
very
precise
control
over
the
harmonic
content
of
the
Patch.
In
adjusting
the
harmonic
content,
the
VCF
acts
somewhat
like
a
tone
control
but
with
much
more
flexibility.
In
fact,
the
MATRIX-12
-
like
its
counterpart,
the
Oberheim
XPANDER
-
gives
you
no
less
than
15
Filter
Modes
with
which
to
control
the
harmonic
content
of
the
Patch.
After
you
have
selected
the
waveforms
for
VCOs
1
&
2,
the
VCF
allows
you
to
determine
the
tonality
of
the
sound
-
by
the
settings
that
you
use
for
FREQ,
RES,
and
MODE
-
and
articulate
this
tone
setting
with
Matrix
Modulation.
It
is
in
the
way
you
use
modulation
that
dynamics
are
added
to
the
Patch.
VCA,
which
stands
for
"Voltage
Controlled
Amplifier",
is
the
circuit
that
controls
the
final
volume
output
of
the
Patch.
Two
VCAs
are
designed
into
the
MATRIX-12
to
provide
an
increased
ability
to
control
Patch
volume.
Here
is
where
Matrix
Modulation™
can
also
be
used
to
apply
volume
or
loudness
dynamics
to
the
Patch.

VCF
Parameters
FREQ
"Frequency"
-
As
we
mentioned
before,
the
VCF
permits
you
to
adjust
the
Patch's
tone
level
by
controlling
the
harmonic
content.
Harmonics
are
upper
frequencies
that
give
each
sound
its
own
identity.
It
is
the
amount
and
structure
of
harmonics
that
allow
our
ears
to
differentiate
between
sounds.
