01  How the JUPITER-50’s Sound Generator is Structured
SuperNATURAL Acoustic Tones
These are SuperNATURAL acoustic tones that can reproduce not only the sound of 
an acoustic instrument, but also the expressiveness of the techniques used when 
playing it.
A dedicated sound engine optimized for each tone is used to automatically analyze 
the phrase played by the musician, and take account of the dierences between 
chordal and melodic playing.
SuperNATURAL acoustic tones represent a completely new sound generator 
technology, which uses Behavior Modeling Technology to model even the distinctive 
response that is specic to each musical instrument.
For example, the SuperNATURAL acoustic tone “violin” lets you obtain—via conventional keyboard playing—a solo violin sound 
that’s imbued with the same realistic expression that you might enjoy if an actual violinist were playing.
In addition, you can use pitch bend, modulation lever, and assignable buttons ([S1], [S2]) to freely simulate the richly expressive 
performance that is characteristic of acoustic instruments.

The JUPITER-50 is Roland’s new synthesizer that inherits the powerful SuperNATURAL sounds and unrivaled real-time 
performance capabilities of the JUPITER-80.
It comes with a generous collection of the latest SuperNATURAL sounds created using Behavior Modeling Technology, making 
possible expression that is richer and more natural than ever before.
This section explains the sounds of the JUPITER-50.
SuperNATURAL
These are proprietary Roland sounds created using Behavior Modeling Technology, which 
enables natural and rich expression that was dicult to achieve on earlier sound generators.
Behavior Modeling Technology
Not only physical modeling of the instruments, Roland takes it a step further by modeling the instrument’s distinctive 
behavior that responds to how the performer plays, resulting in true-to-life, expressive sounds in realtime.
SuperNATURAL Synth Tones
These are SuperNATURAL synth tones, which realistically reproduce sounds ranging 
from vintage analog synths to digital synths. Each synth tone consists of three sets of 
OSC, FILTER, AMP, and LFO, meaning that powerful synth sounds can be created using 
just a single synth tone.
In addition, the behaviors of the oscillators and lters of analog synths have been 
analyzed, allowing their distinctive sounds to be reproduced. The JUPITER-50 contains 
more than 1,500 preloaded sounds, which cover every type of synth sound from analog 
to digital.
Layer Four SuperNATURAL Tones in a Live Set
The JUPITER-50 lets you layer up to four SuperNATURAL tones to create a sound, 
and save this as a “Live Set.”
You can use a Live Set to perform truly impressive and expressive sounds.
To play a Live Set, you need to assign it to the Upper Part.
