What is a Tone?
Although a Tone is the smallest unit of sound handled by the JUPITER-50, it boasts an extravagantly powerful structure based on SuperNATURAL 
sounds. 
“SuperNATURAL Acoustic Tones” not only reproduce the sounds of an acoustic instrument, but also automatically analyze—in a way that’s 
appropriate for each dierent tone—the dierences between the phrases, chords, and melodies played by the performer, and deliver the 
responsiveness that is characteristic of that specic acoustic instrument. Starting with the SuperNATURAL piano, each of these sounds brings you the 
highest possible level of expressive power that has been developed for the sound engines of earlier Roland products.
Each “SuperNATURAL Synth Tone” incorporates three OSC, FILTER, AMP, and LFO sets; this means that powerful synth sounds can be created using just 
a single tone.
The JUPITER-50 contains more than 1,500 preloaded sounds, covering the full range of synth sounds from analog to digital.
What is a Live Set?
In the JUPITER-50’s sound engine, the smallest unit of sound is the “tone”; each tone consists of a SuperNATURAL sound.
Up to four tones can be layered to create impressive and richly expressive sounds.
Such a combination can be saved as a “Live Set.”
What is a Registration?
The combination of sounds assigned to the Upper Part, Solo Part, and Percussion/Lower Part, together with settings for the JUPITER-50 itself, can be 
saved as a single “Registration.”
A Registration can be called up instantly, allowing you to switch sounds as appropriate for the song you’re playing, or to instantly get the settings you 
need for live performance or studio recording.
