Parameter Value Explanation
Keyboard
Keyboard Velocity
Species the velocity transmitted when a key is played.
REAL
The transmitted velocity value will 
correspond to the force with which you strike 
the key.
1–127
The transmitted velocity value will be xed, 
regardless of the force with which you strike 
the key.
Keyboard Velocity 
Curve
LIGHT
The keyboard will have a lighter-feeling 
touch. Since you’ll be able to reach fortissimo 
() without having to play as strongly as 
with the MEDIUM setting, the keyboard will 
feel lighter. This setting makes it easier for 
people with reduced nger strength to play 
the keyboard.
MEDIUM This is the standard keyboard touch setting.
HEAVY
The key will have a heavier-feeling touch. 
Since you’ll need to play more strongly than 
with the MEDIUM setting in order to reach 
fortissimo (), the keyboard will feel heavier. 
This setting allows you to use your playing 
dynamics to add more expression to your 
performances. 
Keyboard Velocity 
Sens
-63–+63
This is a ne adjustment to the keyboard 
sensitivity that’s applied after the Keyboard 
Velocity Curve setting. Higher values will 
cause a greater velocity value to be transmit-
ted for a key-strike of the same force.
MIDI ([F4] button)
Parameter Value Explanation
MIDI
Device ID 17–32
If you want to send and receive system exclusive 
messages, the device ID numbers of both devices 
need to be matched.
Soft Thru OFF, ON
If this is “ON,” MIDI messages received at the MIDI 
IN connector will be retransmitted without change 
from the MIDI OUT connector.
Remote 
Keyboard 
Switch
OFF, ON
Turn this “ON” if you’re using an external MIDI 
keyboard instead of the JUPITER-50’s keyboard. 
In this case, the MIDI transmit channel of your 
external MIDI keyboard does not matter. Normally, 
this can be left at “OFF.”
*  If you want to control the arpeggiator from an 
external MIDI device, turn this “ON.”
USB MIDI
USB-MIDI Thru OFF, ON
If you’re using MIDI via a USB connection, this speci-
es whether the MIDI messages received at the 
USB port/MIDI IN connector will be retransmitted 
without change from the MIDI OUT connector/USB 
port (ON) or will not be retransmitted (OFF).
MIDI Channel
Registration 
Control 
Channel
1–16, OFF
Species the MIDI receive channel on which 
Registrations can be switched by an external MIDI 
device. Turn this “OFF” if you don’t want to switch 
Registrations from a connected MIDI device.
UPPER Part 
Channel,  
SOLO Part 
Channel,  
PERC/LOWER 
Part Channel
1–16
Species the MIDI receive channel that will play 
each of the JUPITER-50’s Parts (PREC, LOWER, 
UPPER, SOLO), and the MIDI transmit channel on 
which each Part will transmit to an external MIDI 
device.

SYNC ([F5] button)
Parameter Value Explanation
Sync
Sync Mode
This selects the synchronization source used by the 
JUPITER-50.
MASTER
The JUPITER-50 will be the synchronization 
master. Choose this setting if you’re using the 
JUPITER-50 on its own without synchronizing 
it to another device, or if you want the tempo 
of an external MIDI device to synchronize 
with the JUPITER-50.
SLAVE
The JUPITER-50 will be the synchronization 
slave. Choose this setting if you want the 
JUPITER-50 to synchronize to MIDI clock 
messages received from an external device.
Sync Output OFF, ON
If this is ON, MIDI clock messages will be 
transmitted to an external MIDI device.
*  These messages will not be transmitted if 
the Sync Mode is “SLAVE.”
Clock Source
This species whether the JUPITER-50 will synchronize to 
tempo data from the MIDI IN connector or to tempo data 
from the USB connector when the Sync Mode is SLAVE.
MIDI
Synchronize to tempo data from the MIDI IN 
connector.
USB
Synchronize to tempo data from the USB 
COMPUTER port.
