The Cherry Audio Mercury-4 is a detailed software emulation of one of the best-sounding and quirkiest polyphonic synthesizers of the late 1970's, the Roland Jupiter-4. It’s the rarest and most sonically unique of the fabled Jupiter series, and we’ve gone to great lengths to recreate the subtle (and not-so-subtle) nuances and character of this beloved classic. Every aspect of Mercury-4 has been expertly modeled upon a vintage Jupiter-4 originally owned by Greg Hawkes of the legendary 80’s new wave band The Cars, and played on their double-platinum 1981 album Shake It Up. In Greg’s words, Mercury-4 “sounds just like my old Jupiter! It’s nice to have it back.”
The Jupiter-4 had its share of disadvantages, including limited patch storage, just four voices of polyphony, and boat-anchor weight. Cherry Audio’s Mercury-4 improves upon the original’s design by offering 16-voice polyphony, infinite patch storage, velocity sensitivity, MPE support, and much more. We’ve even paired it with a fantastic model of the classic Roland Space Echo tape delay.
Originally released in 1978, the Roland Jupiter-4 synthesizer was one of the earliest instruments to combine voice-assign polyphony with digital patch storage - that is, the ability to store and recall sounds to a digital memory and recall them at the touch of a button.
The Jupiter-4 rapidly became the go-to polysynth for numerous English and European acts in the 80's including Duran Duran, Thomas Dolby, The Human League, Simple Minds, and more, and for good reason: the Jupiter-4 sounded fantastic, with a raw, raunchy tone not found in any of the other beloved Juno and Jupiter synths. Its analog oscillators have a uniquely aggressive tone quality, the built-in sub oscillator adds girth, its oddly fast and deep LFO modulation capabilities allow it to create uniquely whacked-out modular synth-like tones, and Roland's famous stereo chorus "ensemble" circuit is beautifully implemented, adding a boatload of width and dimension.
Mercury-4 is available in AU, VST, VST3, AAX, and standalone formats.
A free 30-day demo of Mercury-4 is available. This demo will play white noise periodically, but is otherwise unlimited.
