KORG MS-20
Owner's Manual Supplement
This
supplement
manual for the
Korg
MS-20 is for the synthesist using the External
Signal Processor (ESP)
.
Patch the MS-20
as
shown
on
Diagram
I.
This
is the simplist patch when using the ESP.
Since all musical instruments have different ranges
in pitch, tone,
dynamics
and har-
monic (overtone) content, the setting of the
controls on the
ESP
will vary accordingly.
Setting the Controls
on the
ESP
^
Preliminary
-
If
your instrument has its own controls for tone and volume,
setting
these
is
very important.
For guitar, it has been found that these
settings vary from
one instrument
to another. All give the best response
with
volume
on
"10",
but some
use
the tone on
"0",
some on
"10".
Most use
the
front
(rhythm) pickup, and some
use
both front and rear
(rhythm and lead)
.
Experiment with
your instrument settings
along
with
the
following
settings for the ESP.
1. Signal Level: Set this
so
that at
your loudest signal, the
peak light goes on. (On
guitars where there
is a
strong attack
and quick decay, the peak
light
should
stay on
about two seconds on the
loudest and longest sustaining
note
-
usually the low
E.)
For more sustain,
set at
a
higher level.
2.&
3.
Low and High Cut Frequency: These
controls filter the incoming
signal to get rid of
unwanted noise and excess harmonics, which
can falsely trigger the
pitch to
voltage
converter.
Start
with the fully open setting,
(low cut "O", high cut
"10")
If
the
high cut frequency is set too high, it lets
unwanted harmonics through which
can
falsely trigger the MS-20.
Set it so your lower notes trigger on
the correct pitch
and
your upper notes still trigger the
synthesizer. If
the
low
cut
frequency
is set
too high, the
fundamental
pitch will be cut
out
and
again the synthesizer will falsely
trigger. Set it so the lowest note triggers
correctly. These controls must
be set
properly for the ESP
to
work
accurately. Experiment with
them to find the best
setting for your instrument,
(approximate settings for
guitar; low cut
0,
high cut
5-7),
4. CV Adjust: Set at
10 for unison pitch. By setting this
control lower the control
voltage will be correspondingly lower
along with the final
pitch of the MS-20.
5.
Threshold Level:
For longest sustain,
set at
"10".
This
control sets the length of
the trigger. For certain effects, where
you want to re-trigger
often, it should
be
set at less than
"10".
Once these are
set, you should get a sound from
the MS-20 corresponding
to the settings
on Diagram I.
All controls on the MS-20 work with the ESP
except portamento. You can now
refer to
the
owner's manual for
help in using the controls, patching,
and the different
sounds
you can achieve on the
MS-20.
For expanded effects, the synthesist using the ESP module
can
use our
optional MS01
Voltage
Pedal,
instead of the "wheel"; and our FP1 Footswitch, instead of the push-
button.
