This
Modulation
Routing
is
concerned
only
with
the
amount
of
ENV1
affecting
the
VCFs
Frequency.
The
actual
settings
of
the
Envelope
are
made
in
the
ENV1
Sub-Page.
VALUE
range
is
from
-63
to
+63.
A
Value
of
0
indicates
that
the
Envelope
has
no
effect
on
the
Filter's
frequency
and
a
setting
of
+63
is
the
maximum.
Negative
Values
invert
the
effect of
ENV1
on
the
Filter's
FREQ.
A
Value
of
-63
is
the
maximum
inversion.
VCA
2
Modulation
by
an
ENVELOPE
This
second-stage
VCA
is
used
to
determine
the
final
output
of
the
Patch.
The
volume
of
VCA
2
is
recommended
to
be
set
to
be
0
because
its
output
level
is
normally
controlled
by an
Envelope.
The
Basic
Patch
default
is
Envelope
#2
(displayed
as
ENV
2).
This
function
is
concerned
only
with
the
amount
of
ENV
2
affecting
the
VCA's
output
amplitude.
The
actual
settings
of
the
Envelope
are
made
in
the
ENV2
Sub-
Page.
VALUE
X
range
is
from
-63
to
+63.
A
Value
of
0
indicates
that
the
Envelope
has
no
effect
on
the
VCA
which
results
in
no
sound
when
the
Keyboard
is
played.
A
setting
of
+63
is
the
maximum.
Using
negative
Values
invert
the
effect
of
ENV2
on
the
VCA's
output.
A
Value
of
-63
is
the
maximum
inversion.
KEYBOARD
Although
not
usually
considered
to
be a
Modulation
Source,
the
MATRIX-12's
Modulation
Keyboard
as
well
as
MIDI
IN
keyboard
control
can
be
used
whenever
needed
to
provide
linear
modulation.
And
if
KEYBD
is
selected
as
an
input
to
a
Tracking
Generator,
applying
the
TRACK
to
a
Destination
and
adjusting
the
five
Point
Values
will
cause
the
Keyboard
modulation
control
to
be
non-linear.
We
have
already
seen
how
the
MATRIX-12's
Keyboard
is
used
as
a
Modulation
Source
in
the
normal
operation
of
the
synthesizer.
It
is
used
to
change
the
pitch
of
the
VCOs
as
well
as
the
Frequency
of
the
VCF,
enabling
FREQ
in
PAGE
2
of
VG01,
VCO
2
and
VCF
respectively.
Another
popular
modulation
function
of
Keyboard
control
is
its
use
in
changing
LFO
Speed.
LFO
Speed
Modulation
by
the
KEYBOARD
The
initial
speed
of
the
LFOs
can
be
increased
or
decreased
by
Keyboard
notes:
playing
high
notes
or
low
notes
on
the
Master's
keyboard
will
speed
up
or
slow
down
the
LFO
Speed:
1.
Select
VC01.
Assign
LFO
1
as
a
Modulation
Source
to
its
FREQ.
2.
Select
LF01.
Set
its
SPEED
to
about
25.
3.
Assign
KEYBD
as
the
Modulation
Source
to
LF01
's
SPEED.
VALUE
X
range
is
also
-63
to
+63.
Using
positive
VALUE
X
amounts
causes
the
LFO
to
speed
up
as
higher
notes
are
played
on
the
Keyboard
and
slow
down
when
low
notes
are
played.
Using
negative
amounts
produces
the
opposite
effect:
high
notes
slow
the
LFO
and
low
notes
speed
it
up.
