The
trigger signal
you
use
to
trigger
GEG
operation
can
come
from
the
keyboard
(KBD
TRIG)
or
similar source,
in
which
case
it
is
a
voltage
trigger signal;
or
it
can
come
from
a
switch such
as
the
momentary
switch
(M-SW)
or
a
foot
switch,
in
which
case the
trigger signal
is
like a
switch
in
that
it
just triggers
the beginning of operat-
ion.
Figure
26
is
an attempt
to
convey
the
different
relationships
between
the
two
types of
trigger signal
and
the
envelope
produced. Figure
26
also
shows
how
the
envelope
will
change depending on which
output
jack
you
use.
Note
that
when
the
GEG
output
voltage
is
OV,
the section
you
are controlling
will
operate
at
the
level
of
its
knob
settings.
(In
other
words
it
will
operate
"normally"
as
if
there
were
no
outside
input.)
So,
when you
use
the
GEG,
think
carefully
about
the
type
of
effect
you
want; then
choose
your
trigger signal
and output
jack
accordingly.
