The JUPITER-4 Software Synthesizer is an authentic recreation of the first synthesizer to carry the iconic JUPITER name. Introduced in 1978, the JUPITER-4 kicked off the storied legacy of Roland analog polysynths and sounds exactly like you’d expect—warm, fat, and evocative of synth pop, new wave, and other emerging styles of the era. Now you can have this analog classic in your own productions and performances, complete with modern enhancements that take its creative capabilities further than ever.
Roland’s first polyphonic analog synthesizer launched the JUPITER legacy of best-in-class sound and cutting-edge innovation. Along with its incredible synthesis power, the JUPITER-4 brought digital voltage control and the ability to store eight user presets with new technological wizardry dubbed “Compuphonic.” But 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.
They’ve used proprietary circuit modeling technology to bring the JUPITER-4 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.
