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 com-
mercially 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 con-
nector 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 com-
puter equipped with a USB port in order to receive MIDI mes-
sages 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 ex-
ample, 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.
About the MIDI implementation chart
The MIDI implementation chart lists the MIDI messages that
can be transmitted and received. When using a MIDI device,
compare the MIDI implementation charts to check that the MIDI
messages are compatible.
TIP Detailed MIDI specifications are provided under MIDI implemen-
tation. For more information on MIDI implementation, visit the
