Technical data
lowest
key
determines
the
single
keyboard
control
signal.
A
monophonic
instrument
may
have
more
than
one
tone
oscillator
(the
Minimoog
has
three),
and
the
oscillators
might
be
tuned
to
produce
a
chord.
But,
if
the
keyboard
is
monophonic,
all
the
oscillators
may
follow
the
single
keyboard
control
signal
and
produce
parallel
chords,
but
not
polyphony
(several
independent
voices).
So
the
KBD
OUTPUT
might
be
used
to
control
several
external
oscillators,
but
no
external
manipulation
of
the
KBD
OUTPUT
signal
will
make
the
keyboard
of
the
Multimoog
become
polyphonic
like
an
organ.
The
KBD
OUTPUT
helps
make
the
Multimoog
fully
compatible
with
other
synthesizers
and
the
largest
modular
systems.
It
conveys
important
information
to
the
outside
world—which
key
on
the
Multimoog
is
being
depressed.
The
KBD
OUTPUT
functions
as
an
input
when
its
associated
attenuator
(pot)
is
turned
fully
counter
clockwise
to
the
"click"
position.
In
this
case, a
control
signal
fed
into
the
KBD
OUTPUTjack
replaces
the
internal
keyboard
signal.
Then
the
external
signal
controls
both
the
pitch
of
both
oscillators
and
the
cutoff
frequency
of
the
filter,
and
the
keyboard
of
the
Multimoog
controls
nothing.
(Note
that
the
external
signal
behaves
exactly
as
though
it
were
the
internal
keyboard
signal.
For
instance,
if
you
place
the
OSCILLATORS
switch
to
the
DRONE
setting,
the
external
signal
will
no
longer
control
the
oscillators,
(but
will
continue
to
control
the
filter
cutoff
frequency).
When
the
KBD
OUTPUT
is
used
as
an
input,
you
can
easily
switch
from
normal
Multimoog
keyboard
control
to
an
overriding
external
control
source—such
as
the
highest
note
played
on
the
keyboard
of
the
Polymoog.
Of
course,
the
oscillators
and
filter
could
be
controlled
using
the
OSC
A&B
INPUT
and
FILTER
INPUT;
but
these
control
inputs
add
to
the
internal
keyboard
control
signal.
That
means
you
would
constantly
have
to
worry
about
which
key
you
last
struck
on
the
Multimoog
(it
adds)
when
switching
from
Multimoog
to
Polymoog
keyboard
control.
The
control
signal
from
the
key
board
of
the
Polymoog
will
simply
replace
the
keyboard
signal
in
the
Multimoog
when
the
KBD
OUTPUT
is
used
as
the
input.
The
pitch
of
the
oscillators
of
the
Multimoog
will
always
agree
with
the top
note
of
the
Polymoog
keyboard
in
this
case.
RIBBON
OUTPUT
The
RIBBON
OUTPUT
is
not
subject
to
front
panel
control.
The
RIBBON
OUTPUT
always
provides
the
signal
created
by
depressing
the
PITCH
ribbon
at
the
left
of
the
keyboard.
The
signal
from
the
PITCH
ribbon
may
be
scaled
for
external
use
with
the
attenuator
associated
with
the
RIBBON
OUTPUT.
The
RIBBON
ROUTING
switch
has
no
effect
on
the
RIBBON
OUTPUT
jack
signal.
KBD
FORCE
OUTPUT
The
KBD
FORCE
OUTPUT
is
not
subject
to
front
panel
control.
The
amount
of
force
exerted
on
the
keyboard
always
determines
the
size
of
(D.C.)
signal
that
appears
at
the
KBD
FORCE
OUTPUT.
Attenuation
of
this
signal
must
be
achieved
externally.
GLIDE
ON/OFF
CONTROL
The
GLIDE
jack
is
functional
only
when
the
GLIDE
switch
on
the
front
panel
is
switched
OFF.
(Also,
if
the
GLIDE
control
near
VOLUME
is
set
to
"0,"
use
of
theGUDE
jack
is
meaningless.)
The
Moog
1121
Footswitch
may
be
used
to
turn
glide
on
or
off
by
inserting
its
plug
into
the
GLIDE
jack.
(The
amount
of
glide
always
remains
under
control
of
the
rotary
GLIDE
control).
MODULATION
MODULATION
is
a
dual
function
3/16"
stereo
jack.
It
acts
as
both an
input
and
an
output
for
MODULATION
section
(control)
signals.
As
an
output,
it
can
externalize
whatever
signal
is
provided
by
the
SOURCE
selector.
As
an
input,
it
routes
control
signals
from
any
source
directly
to
the
ROUTING
selector.
Several
simple
switching
or
attenuation
tasks
may
be
accomplished
using
the
MODULATION
jack.
We'll
review
these
simpler
uses
first
before
taking
up
the
subject
of
MODULATION
section
(control)
signal
routing.
The
Moog
1121
Footswitch
may
be
used
to
turn
modulation
on
or
off
by
inserting
its
plug
into
the
MODULATION
jack.
(The
amount
of
modulation
remains
under
control
of
theMOD
AMOUNT
wheel).
The
1121
can
be
very
handy
when
y.ou
don't
have
a
spare
hand
to
turn
vibrato,
shakes,
sample
and
hold
patterns,
etc.
on
and
off.
You
can
rewire
any
volume
pedal
(orjustapot)
to
control
the
amount
of
modulation
using
the
MODULATION
jack.
Remember
to
use
a
3/16"
stereo
plug
