Roland has introduced the JUPITER-4 Software Synthesizer, the latest addition to their Legendary instrument series, available through Roland Cloud.

Released in 1978, the JUPITER-4 was Roland’s first polyphonic synthesizer and the first to carry the JUPITER name. With the JUPITER-4 Software Synthesizer, the sound of this classic synth is now available as a computer-based plug-in and as a PLUG-OUT for the SYSTEM-8 synthesizer keyboard.

Here’s what they have to say about it:

“Roland products with the JUPITER name represent the current pinnacle of the company’s synthesizer development, a benchmark started over four decades ago with the JUPITER-4. In addition to incredible analog synthesis power, it brought then-revolutionary digital voltage control and the ability to store eight presets with technological wizardry dubbed “Compuphonic.” But the JUPITER-4’s real appeal was its warm, fat voice and inviting hands-on panel, which inspired synth pioneers to create the defining sounds of synth-pop, new wave, and other emerging styles of the late ’70s and early ’80s.

Roland’s evolving Analog Circuit Behavior (ACB) technology brings the JUPITER-4 to life through careful analysis of original hardware units, circuit diagrams, and other historical data. This information is then used to recreate the authentic circuit behaviors of the vintage instrument—including all the beloved quirks and instabilities—giving the JUPITER-4 Software Synthesizer a breathtakingly accurate sound that buzzes with unique character.”

The JUPITER-4 software synth features new Circuit Mod and Condition controls, which let you adjust the overall character. The JUPITER-4 also includes enhanced features for modern workflows, including extended oscillator range, adjustable noise, velocity sensitivity, sub-oscillator volume control, and a flexible arpeggiator.

In addition, phaser, flanger, overdrive, reverb, and delay effects are available to complement the lush Ensemble chorus effect from the original keyboard.

The plug-in flows easily into modern DAW environments with a resizable UI, support for VST3, AAX, and AU formats, and native compatibility with Apple silicon. It also offers full integration with the Roland SYSTEM-8 Synthesizer. Users can control the software plug-in from the keyboard’s panel, and PLUG-OUT functionality turns the SYSTEM-8 into a standalone, eight-voice JUPITER-4 for stage and studio playing.
