Korg MS-20 Owner's Manual Supplement

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.
Here are some more patches to work with!
