* 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 perform with it while using a sequencer.
• Equipped with earlier and later filters:
Different VCFs were installed in the earlier and later versions 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.

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 handle tools to avoid scratching panels, etc.
Provide a sufficiently large work space to complete the assembly 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.

VCF setting
The VCFs (high-pass filter & low-pass filter) of the original MS20 are differentiated into the earlier and later filters, depending
on the production date.
Since the circuitry of these two types of filters differs, they have
different sound quality characteristics, although their frequency
characteristics are similar.
The MS-20 Kit is equipped with both types of filters for you to
select as desired.
Setting procedure
Insert the short pin into the 3-pin header on the back of the VR
circuit board (large).
When the short pin is inserted into the later filter (late type), the
later filter is set.

4. About MIDI
The MIDI IN connector and USB port on the MS-20 Kit are some
of the main differences between it and the original MS-20.
By connecting the MS-20 Kit to a computer, you can perform
with it while using a sequencer.
Connecting MIDI devices
In order to transmit/receive MIDI information, you can use commercially available MIDI cables. Connect the MIDI connector of
the MS-20 Kit to the MIDI connector of the external MIDI device
where information will be exchanged.
MIDI IN connector: This receives MIDI messages from other
MIDI devices. This should be connected to the MIDI OUT connector of the other device.
The only MIDI messages that can be received at the MIDI IN
connector are note messages (Velocity is disabled) on MIDI
channel 1 (fixed).
TIP If a Note On message with a note number of 92 or more is re-
ceived, the message will become invalid, and the sound being
produced will stop. It will also be invalid if a note number is 11 or
less; however, the sound will continue to be produced.
Connecting a computer
Use a USB cable to directly connect the MS-20 Kit to a computer equipped with a USB port in order to receive MIDI messages in the same way as with the MIDI connectors.
The only MIDI messages that can be transmitted and received
at the USB port are note messages (Velocity is transmitted fixed
at 64 and reception is disabled) on MIDI channel 1 (fixed).
TIP The only MIDI messages that are transmitted are note messag-
es transmitted when the keyboard is played. Messages, for example, for pitch bend and modulation, will not be transmitted.
TIP When connecting via USB, the KORG USB-MIDI driver must be
installed. Download the KORG USB-MIDI driver from the Korg
Web site ( http://www.korg.co.jp/English/Distributors/ or http://
www.korg.com/ ), and then install it according to the instructions
in the document included with the driver.

Comporte une prise MIDI IN et un port USB: Vous pouvez
brancher le MS-20 Kit à un ordinateur et jouer sur l’instrument
accompagné d’un séquenceur.
Équipé des filtres anciens et récents : Plusieurs VCF ont été
installés dans les versions anciennes et récentes du MS-20
d’origine. Le MS-20 kit est équipé des deux types de filtres, qui
peuvent être sélectionnés avec un fil de raccordement sur la
carte du circuit.
Caractéristiques de l’adaptateur secteur: Bien que l’alimentation soit passée à un adaptateur secteur, les caractéristiques
de tension interne sont identiques à celles de l’instrument original.
Assemblage
Précautions avant l’assemblage
Éviter les blessures lors de la manipulation de pièces
Maniez les cartes des circuits avec soin pour éviter les blessures qui pourraient être causées par accident par des pièces
protubérantes. Protégez vos mains en portant des gants de travail (en coton). De plus, veillez à laver vos mains avec du savon
lorsque vous avez terminé la procédure d’assemblage.
Aligner correctement les vis et les écrous avant le serrage
Le serrage des vis et des écrous en angle peut endommager
l’enfilage, ce qui peut les empêcher d’être complètement serrés. Veillez à aligner les vis correctement avant de les serrer.
De plus, faites attention à ne pas serrer les vis en exerçant une
force excessive et à ne pas trop les serrer, car les pièces pourraient être endommagées.
Éviter les blessures et la rayure des pièces lors de l’utilisation d’outils
Lorsque vous utilisez des outils pour serrer des vis et écrous,
faites attention à éviter les blessures, à vos doigts notamment.
De plus, maniez les outils avec soin pour éviter de rayer les
panneaux, etc.
Organisez un espace de travail suffisant pour effectuer la procédure d’assemblage, et préparez des tapis de travail pour ne pas
rayer les pièces.
Éviter de perdre les vis et écrous
Maniez les vis et écrous fournis avec soin afin de ne pas les
perdre. De plus, n’utilisez pas d’autres vis et écrous que ceux
fournis pour l’assemblage, et n’utilisez pas les vis et écrous
fournis à d’autres fins.
ASTUCE Des vis et écrous supplémentaires sont fournis. Utilisezles en cas de besoin de remplacement.
Outils à préparer
Tournevis Phillips (+) : Utilisez le tournevis convenant à la
taille de la vis. Utiliser un tournevis de la mauvaise taille pourrait
endommager la vis ou vous empêcher de bien la serrer.
Clé polygonale (fournie) : Utilisez-la pour serrer les écrous
hexagonaux de 11 mm et 12 mm.
