When it was introduced in 1978 the JP-4 brought digital voltage control and the ability to store eight user-presets with new “Compuphonic" memory system-- Although the real magic was in grabbing the panel controls and designing big, beautiful tones, which led synth pioneers to create timeless tracks that continue to influence musicians today.

With this new software re-issue, Roland used their proprietary circuit modeling technology (ACB) to bring the JP to life in your DAW or SYSTEM-8. The ACB process involves carefully analyzing original hardware units, circuit diagrams, and other historical data. They then use this information to recreate the authentic circuit behaviors of the vintage instrument, including all the beloved quirks and instabilities... This is what gives the JUPITER-4 Software Synthesizer its breathtakingly lifelike sound that buzzes with unique character.

While the JUPITER-4 only has a single VCO, it sounds positively massive. The combined characteristics of its oscillator, filter, LFO section, and other components make it sound thick and warm. And its built-in ensemble chorus pours on a helping of lusciousness that takes it to a new level. This is where ACB really shines, giving the ability to capture the behavior and interaction of all the components working together to create sonic magic.

New features:
During the development of the JUPITER-4 plug-in, Roland found areas to improve the original hardware while keeping the authentic experience intact. With new features like extended oscillator range, adjustable noise, velocity sensitivity, sub-oscillator volume control, and a more flexible arpeggiator.

Circuit Mod:
Vintage synths like the JUPITER-4 had internal trim controls that allowed technicians to tweak various analog components when they drifted out of spec. But sometimes, “out of spec” created a sound that was unique, interesting, or extraordinary. Realized through the latest ACB advancements, the new "Circuit Mod" function lets you sweep through multiple trims using a single macro control. Along with the Condition parameter, which simulates the effects of aging, you can dial in everything from a factory-primed JUPITER-4 to a road-worn synth that hasn’t seen a tech bench in decades.

With the System-8:
You can change the JUPITER-4’s plug-in panel to match the SYSTEM-8, or use the PLUG-OUT functionality to turn your SYSTEM-8 into a standalone, eight-voice JUPITER-4 that you can play in the studio or on stage.


The JP-4 Software Synthesizer is available with Roland Cloud Pro and Ultimate memberships or a Lifetime Key purchase.
