Introduction
Thank you for purchasing the Korg MS-20 Kit Monophonic Syn-
thesizer.
To ensure trouble-free enjoyment, please carefully read this
manual and use the product correctly. In addition, be sure to
store this manual in a safe place for future reference.
The MS-20 Kit is a reincarnation of the original MS-20, which
was released in 1978.
The MS-20 Kit uses analog circuitry to faithfully recreate the
sound and characteristics of this legendary instrument. We rec-
ommend reading the reprint of the original Owner's Manual for
in depth descriptions of the various controls and their functions.
Since this manual contains additional information and details on
new functions, we recommend that you carefully read this man-
ual together with the original Owner's Manual.
The original Owner's Manual contains terms and phrases used
*
at the time of the original product release in 1978. The manual
may also contain information that differs from the MS-20 Kit or
may mention products that are no longer available. In addition,
the specifications contain details and measurement standards
from the time of the original MS-20 release, which differ from
those of the MS-20 Kit.
About the MS-20 Kit
The MS-20 Kit and the original MS-20 differ in the following
ways:
• Equipped with MIDI IN connector and USB port:
By connecting the MS-20 Kit to a computer, you can per-
form with it while using a sequencer.
• Equipped with earlier and later filters:
Different VCFs were installed in the earlier and later ver-
sions of the original MS-20. The MS-20 Kit is equipped with
both filters, which can be selected with a jumper wire on
the circuit board.
• AC adapter specifications:
Although the power supply has been changed to an AC
adapter, the internal voltage specifications are identical to
the original design.
Assembly
Precautions before assembly
Avoiding injuries while handling parts
Carefully handle the circuit boards to avoid injuries that could be
inadvertently caused by protruding parts. Protect your hands by
wearing (cotton) work gloves. In addition, be sure to wash your
hands with soap when finished with the assembly procedure.
Properly aligning screws and nuts before tightening
Tightening screws and nuts inserted at an angle may damage
the threading, preventing them from being fully tightened. Be
sure to align screws properly before tightening them.
In addition, be careful not to tighten screws with excessive force
or overtighten them, otherwise the parts may be damaged.
Preventing injuries and scratches to parts while using tools
When using tools to tighten screws and nuts, be careful to avoid
injuries, for example, to your fingers. In addition, carefully han-
dle tools to avoid scratching panels, etc.
Provide a sufficiently large work space to complete the assem-
bly procedure, and prepare work mats so parts will not be
scratched.
Preventing loss of screws and nuts
Carefully handle the included screws and nuts so they will not
be lost. In addition, do not use screws or nuts other than those
included for assembly, and do not use the included screws and
nuts for any other purpose.
TIP Extra screws and nuts are included. Use them as spares.
Tools to prepare
Phillips (+) screwdrivers: Use the screwdriver that's appropri-
ate for the size of the screw. Using a screwdriver of the wrong
size may damage the screw or may not properly tighten the
screw.
Box-end wrench (included): Use for tightening 11 mm and 12
mm hex nuts.
