Performing
When you play the keyboard, you hear the sound of the part(s) that 
you selected in ““Selecting the Parts to Perform” (p. 14).
The JUPITER-X lets you customize performance-related settings so that 
you can perform in the way that’s best for you.
Performing Arpeggios
To start arpeggio performance, make the I-ARPEGGIO [ON/OFF] button 
lit.
To stop arpeggio performance, press the button once again to make it 
go dark.
& “I-ARPEGGIO” (p. 20)
Making Performance Settings
Using the Controllers
You can use the controllers of the controller section to quickly 
operate the sound parameters or to modify the sound to create 
excitement in your performance.
You can also assign functions to a footswitch or expression pedal, 
and use it to switch scenes or turn the arpeggio on/o while you 
perform.
To assign functions to controller, make settings in the system 
parameters.
& “List of functions that can be assigned to the controllers” 
(p. 47)
Specifying the Key Range
By specifying the key range, a sound that you play or an arpeggio 
performance can be restricted to a specic region of keys.
For example, you could specify that the left-hand region of the 
keyboard plays only the bass part, so that an arpeggiated bass 
continues without being aected by what you play in the right-hand 
region of the keyboard. Alternatively, you could specify fades between 
multiple parts to create gradations between sounds.

will sound.
Make these settings when you want 
dierent key ranges to play dierent tones.
Specify the lower limit of the key range.

Explanation
ARP PART
K-Range Lo C-–G9
Species the lower pitch limit that is 
sounded by the arpeggio. If the arpeggio 
attempts to play a note that is lower than 
this, the octave is raised.
K-Range Oct 0–12
Species the number of higher octaves in 
which the arpeggio is sounded, relative to 
K-Range Lo.
If the arpeggio attempts to play a note 
that is higher than this range, the octave 
is lowered.
Oct Range -3–+3
Species the range of octaves in which the 
arpeggio is sounded.
You can specify whether the arpeggio is 
sounded in the octave(s) above (+) or below 
(-) the notes you play.
Transpose -36–+36 Shifts the arpeggio notes in semitone steps.
ARP COMMON
In Range Low
C-–G9
Species the range that is detected for 
arpeggio performance. Pressing a key 
outside the specied range does not aect 
the arpeggio function.
In Range Upp

Scene” (p. 13).
Performing with a Connected Mic (Vocoder)
The “Vocoder” adds eects to a human voice. If you run your voice 
through the vocoder, you can give it a toneless, robotic tone. Control 
the pitch by playing the keyboard.
1. Connect a microphone to the rear panel MIC IN jack.
NOTE
The JUPITER-X supports dynamic microphones and electret 
condenser microphone (plug-in power system). It does not 
support condenser microphones.
2. Use the rear panel [MIC GAIN] knob to adjust the 
volume.
Make detailed adjustments to the MIC IN volume after you 
select the sound.
Initially, set the knob to approximately the center position.
3. Select part 1, and then press the [MODEL BANK] 
button to make it light.
4. Press the [MODEL BANK] button and then press the 
[15] button.
* With the factory settings, “VOCODER” is assigned to the model bank of 
the [15] button.
You can change the model bank that is assigned.
& “Customizing the model bank” (p. 15)
5. Use the [1] knob to select a vocoder sound (two 
types).
6. While playing the keyboard, vocalize into the 
microphone.
Use the [MIC GAIN] knob to make ne adjustments to the 
volume.
