Connecting an External MIDI Device
About MIDI
MIDI (Musical Instrument Digital Interface) is a standard 
specication that allows musical data to be transferred between 
electronic musical instruments and computers. If a MIDI cable 
is connected between devices equipped with MIDI connectors, 
you’ll be able to play multiple devices from a single MIDI keyboard, 
perform ensembles using multiple MIDI instruments, program the 
settings to change automatically as the song progresses, and more.
About MIDI Connectors
The JUPITER-80 is equipped with the following 
three types of MIDI connectors, each of which has 
the following role.
MIDI IN connector
This connector receives MIDI messages that are sent from an 
external MIDI device. When the JUPITER-80 receives MIDI messages, 
it can respond by playing notes, switching sounds, etc.
MIDI OUT connector
This connector transmits MIDI messages to an external MIDI device. 
Use it when you want to control an external MIDI device.
MIDI THRU connector
MIDI messages received at MIDI IN are re-transmitted without 
change from this connector to an external MIDI device. Use 
this in situations such as when you use multiple MIDI devices 
simultaneously.
Using the JUPITER-80 as a Master 
Keyboard (External Part Settings)
You can connect external MIDI devices to the JUPITER-80’s MIDI 
OUT connector, and use the JUPITER-80 to control the connected 
MIDI devices.
MEMO
External Part settings are saved in the Registration.

Enabling the External Part Settings
1.  In the Registration External Part screen (p. 31), set the MIDI 
out Setting to “EXTERNAL.”
The External Part settings will be enabled.
MEMO
•  If the MIDI Out Setting is set to INTERNAL, Parts that are turned 
on will transmit MIDI messages. 
Choose the INTERNAL setting if you want a Part’s performance 
data to be recorded on a MIDI sequencer, or if you want to 
control the JUPITER-80 from a MIDI sequencer.
•  The MIDI channel of each Part is specied by the system 
parameter “Part Channel” (p. 85).
