Basic Structure
Tone
The sounds that you play from the keyboard are called “tones.” 
A tone consists of an oscillator (OSC) which creates the basis 
of the sound, and a lter and eect (MFX) that modies that 
sound. The types of oscillator, lter, and eect dier depending 
on the model.
Model
A “model” is a sound engine such as JUPITER-8, JX-8P, or PR-A which reproduces 
the sound of a specic vintage synthesizer, or a sound engine that has 
distinctive functionality.
The JUPITER-X is equipped with numerous models, meaning that a single 
JUPITER-X unit can be used as if you own a variety of dierent synthesizers. 
Each model is equipped with distinctive parameters and eects, and you can 
use these to create tones that are unique to those models.
Category
Classications of instrument or types of sound, such as Ac.PIANO or Synth 
Lead, are called “categories.”
Part
A “part” is a location to which you can recall a tone and save it 
together with settings such as pan and EQ.
Each scene has ve parts: for parts 1–4 you can select a 
synthesizer tone, and for part 5 you can select a drum kit tone.
I-ARPEGGIO
This analyzes your keyboard performance, and plays multiple 
parts using appropriate arpeggio patterns.
As you play slowly or rapidly, this automatically switches 
arpeggio patterns based on your performance. By simply 
selecting a type and rhythm, you can use a wide variety of 
arpeggio patterns.
You can create a song using the following workow: 
“Performing with I-Arpeggio” 0 “When you nd a phrase 
that you like, adjust it with Step Edit” 0 Import it into your 
computer DAW as MIDI data.”
System
You can apply eects to the audio signal from the scene, and 
output the sound from an external device connected to the 
OUTPUT jacks or the PHONES jack, or from the speakers that are 
built into the JUPITER.
The system settings let you edit the system eects. Unlike the 
scene eects, these parameters keep their settings even when 
you switch scenes.
Controller
“Controllers” include the keyboard, the buttons, knobs, sliders 
on the panel, pitch bend and modulation, and a damper pedal 
etc. connected to the rear panel. Performance data generated 
when you press or release a key or press the damper pedal is 
converted into MIDI messages and sent to each part or to an 
external MIDI device.
Interface
This section lets you input/output MIDI, and transfer audio 
and MIDI data to and from another device that’s connected via 
Bluetooth or USB. If you connect a USB ash drive to the rear 
panel, you can use it to save or load scene and tone data.
