1-11 Voltage Processors (VP)
We
designed
the
Korg
PS
and
MS
synthe
sizer
series
so that
any
module
can
be con-
trolled
by
a voltage
within
the
range
of
SV~+5V.
This
standardization
gives
you
greater
flexi-
bility
and
more
precise
control
over
synthesiser
operation.
The
voltage
processors
take
the
—5~+5V
output
signal
from
some
control
voltage
source
and
change
its range
and
phase.
As
shown
in
figure
32,
they
act
like
a
lens
and
change
the
way
the
voltage
looks
in
accord
ance
with
the
limiter
(A
and
B) settings.
When
no
input
is connected
to one
of the
VP's,
it
operates
as
if
it
has
a
—4.5V
input
So
you
can
use
it
as
a
fixed
voltage
source;
for
rough
adjustment
of
output
voltage,
use
limiter
B;
for
fine
adjustment,
use
limiter
A.
For
example,
if you
connect
a VP
output
to the
SG
section
PWM
input,
you
can
use
limiters
A and
B to control
pulse
width.
