Technical data
The
usefulness
of
being
able
to
bend
a
single
oscillator
is
fairly
apparent,
but
perhaps
you
are
wondering
why
there
is
an
OFF
position
for
RIBBON
ROUTING.
Wouldn't
the
result
be
the
same
if
you
simply
didn't
use
the
PITCH
ribbon?
Not
exactly.
The
Multimoog
is
an
open
system
synthesizer
that
can
control
other
synthesizers.
Suppose
you
wished
to
bend
the
oscillators
of
an
external
synthesizer
but
not
those
of
the
Multimoog?
So,
we
include
an
OFF
position,
for
internal
routing
purposes
only.
In
addition,
the
KBD
&
TRIG
EXT
OUTPUT
makes
the
RIBBON
output
available
(or
not)
at
the
KBD
output
on
the
rear
of
the
Multimoog.
For
more
information,
see
the
OPEN
SYSTEM
section
of
this
manual.)
TRIGGER
SOURCES
A
trigger
is
a
signal
that
acts
to
start
and
end
the
action
of
the
FILTER
CONTOUR
and
LOUDNESS
CONTOUR
sections
of
the
Multimoog.
A
trigger
signal
triggers
sound
The
particular
type
of
signal
generated
by
the
Multimoog
is
refered
to
as
an
"S-
Trigger",
short
for
"switch
trigger".
The
S-Trig
acts
like
a
switch;
whenever
a
key
on
the
keyboard
is
depressed
an
S-Trigger,
or
drop
to
zero
volts,
is
produced.
An
S-Trig
begins
when
a
key
is
depressed,
and
ends
when
all
keys
are
released.

A

is
used
to

the
contour
generators
to
initiate
and
terminate
musical
sounds.
