timing
controls
allow,
regardless
of
how
long
a
key
is
depressed.
In
the
sustain
mode
to
the
left,
the
LOUDNESS
CONTOUR
generates
a
three-part
contour
/*7
^*y
whose
middle
portion
will
be
sustained
as
long
as
a
key
is
depressed.
I
n
this
case,
the
release
part
of
the
contour
becomes
operable
only
when
all
keys
are
released.

Controls
timing
of
the
last

part
/ ^
of
the
loudness
contour
from
1
msec,
to
10
seconds.
The
RELEASE
control
is
operable
over
its
full
range
only
when
the
RELEASE
switch
in
the
row
of
switches
is
switched
to

KEYBOARD
TOUCH
The
KEYBOARD
TOUCH
section
provides
use
and/or
routing
of
the
fluctuating
D.C.
signal
produced
by
the
force
sensor
under
the
keyboard
of
the
Multimoog.
The
EFFECT
switch
selects
to
provide
direct
or
cascaded
use
of
the
force
signal.
I
n
the
BEND
position,
the
force
signal
is
used
directly
as
a
control
voltage
that
may
be
routed
to
various
control
inputs
using
the
DESTINATION
selector.
In
the
MOD
position,
the
force
signal
is
used
to
open
and
close
a
VCA
which
passes
signals
provided
by
the
SOURCE
selector
in
the
MODULATION
section.
Here
we
have
control
over
a
controller,
hence
"cascaded"
control.
All
signals
passing
through
the
KEYBOARD
TOUCH
section
are
controlled
in
amount
by
the
AMOUNT
control,
which
attenuates
the
signal
that
is
in
use.
Routing
of
a
chosen
signal
is
accomplished
using
the
DESTINATION
selector.
DESTINATION
KEYBOARD
TOUCH
16
DESTINATION
Determines
the
destination
of
the
control
signal
in
use
in
the
KEYBOARD
TOUCH
section
as
follows:
OSC
A&B—Routes
the
selected
signal
to
the
frequency
control
inputs
of
both
audio
oscillators
(A&B).
OSC
A—Routes
the
selected
signal
to
the
fre
quency
control
input
of
OSCILLATOR
A
only.
OSC
A&B
FILTER—Routes
the
selected
signal
to
the
frequency
control
inputs
of
both
audio
oscillators
(A&B),
and
the
cutoff
frequency
control
input
of
the
FILTER
section.
FILTER—Routes
the
selected
signal
to
the
cutoff
frequency
control
input
of
the
FILTER
section.
SYNCH
A
TO
B—Synchronizes
OSCILLATOR
A
to
OSCILLATOR
B,
and
routes
the
selected
signal
to
the
frequency
control
input
of
OSCILLATOR
A
only.
^y
I
A—Routes
the
selected
signal to
the
waveshape
control input
of
OSCILLATOR
A
only.
Use
of
a
positive
voltage
is
analogous
to
a
clockwise
movement
of
the
WAVESHAPE
control
for
that
oscillator
(from
front
panel
setting).
And
the
converse.
17
AMOUNT
Attenuates
the
signal
selected
for
use
by
the
KEYBOARD
TOUCH
section.
Arbitrary
calibration;
the
"10"
setting
passes
the
full
signal—"0"
attenuates
the
signal
completely.
The
AMOUNT
control
is
used
in
conjunction
with
force
exerted
on
the
keyboard
to
"scale"
the
desired
effect.
18
EFFECT
Selects
to
determine
how
the
signal
from
the
force
sensor
will
be
used.
In
the
BEND
position,
this
signal
is
used
directly—a
D.C.
voltage
that
fluctuates
according
to
the
amount
of
force
exerted
on
the
keyboard.
OFF
provides
a
way
of
removing
the
effect
of
the
KEYBOARD
TOUCH
section
instantly.
When
MOD
is
selected,
the
signal
from
the
force
sensor
is
used
to
open
and
close
a
VCA.
As
panel
graphics
indicate,
the
signal
flowing
through
that
VCA
is
determined
by
the
SOURCE
selector
in
the
MODULATION
section.
MODULATION
The
MODULATION
section
is
responsible
for
routing
control
voltages
from
several
sources
to
several
destinations.
As
indicated
in
the
diagram,
the
SOURCE
selector
determines
the
source
of
the
modulation
signal;
the
ROUTING
selector
determines
the
destination
of
the
modulation
signal.
All
modulations
are
attenuated,
or
lessened
by
the
MOD
AMOUNT
wheel
on
the
Performance
Panel.
Progressive
attenuation
occurs
as
the
MOD
AMOUNT
wheel
is
rotated
toward
you.
