FM/LAG
The
FM/LAG
section
involves
the
functions
of
two
independent
modulation
generators,
listed
here
in
the
same
Sub-Page.
"FM",
which
stands
for
Frequency
Modulation,
allows
you
to
achieve
a
form
of
special-effect
modulation
that
is
routed
to
VC01
or
the
VCF
Frequency.
Explained
in
more
detail
below,
FM
basically
involves
a
high-frequency
modulation
of
VCO1
or
the
VCF
to
obtain
tone
colors
not
possible
with
conventional
LFO
modulation.
The
LAG
Processor
in
the
MATRIX-12
is
a
circuit
that
smooths
out
otherwise
sharp
transitions
in
a
Modulation
Source.
LAG
takes
any
one
of
the
MATRIX-12's
27
Sources
of
Modulation
and
slows
the
transition
from
its
start
point
to
its
end.
The
most
common
use
of
LAG
is
in
producing
Portamento,
although
as
a
separate
function
can
be
used
to
achieve
a
multitude
of
special
effects.
When
used
to
generate
Portamento,
LAG
produces
the
smooth
"gliding"
from
note
to
note
by
slowing
the
normal
transition
between
the
notes
as
keys
are
played
on
the
Keyboard.
FM
Frequency
Modulation
-
or
"FM"
-
is
a
basic
analog
concept,
derived
in
part
from
broadcast
technology
used
in
radio
and
television
transmission
and
reception.
The
evolution
of
Linear
FM
as
a
technique
for
sound
synthesis
has
become
possible
in
recent
years
because
of
major
breakthroughs
in
digital
signal
processing
and
oscillator
stability.
The
fundamental
idea
of
FM
is
that
if
you
take
two
oscillators
and
modulate
one
of
them
(called
the
Carrier)
by
the
other
(called
the
Modulator),
a
series
of
new
overtones
or
harmonics
will
be
generated.This
new
harmonic
structure
is
related
to
the
frequency
(pitch)
and
the
amplitude
(loudness)
of
the
Modulator.
If
the
frequency
and
amplitude
of
the
Carrier
is
changed,
yet
another
set
of
harmonics
is
produced.
Thus,
the
synthesist
now
has
a
whole
new
set
of"
tools"
with
which
to
create
sounds
that
will
be
different
from
what
the
synthesizer
is
normally
capable
of
producing.
In
the
MATRIX-12,
VCO2
is
used
to
modulate
either
the
frequency
of
VC01
or
the
frequency
of
the
VCF.
VCO
2
is
the
Modulator
and
either
VC01
or
the
VCF
(although
not
actually
an
oscillator)
are the
possible
Carriers.
FM
in
the
case
of
the
VCF
is
best
heard
when
RES
(Resonance)
in
the
VCF/VCA
Page
is
set
to
its
maximum,
causing
the
VCF
to
oscillate.
The
VCF
then
becomes
the
second
"oscillator11.

"F.M.

(Amount)
This
parameter,
as
described
previously,
controls
the
amount
of
VCO

Triangle
wave
modulating
VC01
orthe
VCF.
This
is
the
"amplitude"
or
depth
portion
of
FM.
VALUE
range
is
from
0
to
+63
where
0
is
no
effect
and
63
is
maximum
amplitude.
