Supersonic Compuphonic

A sibling of the legendary JUPITER-4, this rare and wonderful synthesizer from 1979 features an evocative voice with a thick, rich sound, and is increasingly sought after on the used market. Sonically accurate down to the circuit level, the versatile PROMARS plug-in cranks out big bass and lead tones with the unmistakable character of Roland synths from the era.

Big Little Brother

Initially designed as a "kid brother" to the JUPITER-4, the deceptively small PROMARS married the stability and flexibility of microprocessor control with the rich sound of analog, and was one of the first synths with onboard memory. This powerful monophonic instrument boasted fat buzzy leads and a powerful low end, proving big things often come in little packages.

Otherworldly Tones

While the JUPITER-4 featured one VCO and one sub-oscillator per voice, PROMARS had two of each. Users could detune them to produce a distinctive unison chorus effect, producing sounds like a four-VCO synthesizer. It sounded positively huge, making it a go-to synth for fat, growling basses and searing lead tones.

Plug In Your Own PROMARS

Our software version of PROMARS perfectly recreates the sound of this rare, vintage instrument using original design specs and a detailed, part-by-part analysis of each analog circuit. But it also features some new capabilities only found in the plug-in:

  • Each oscillator has extended range for more flexibility
  • The LFO includes a new Random waveform setting
  • Full user control of noise and pulse width
  • Advanced arpeggiator with tempo sync
  • Modern effects: reverb, bit-crusher, and tempo-syncing delay
Hardware Integration

PROMARS is also a PLUG-OUT synthesizer that can be hosted in Roland’s SYSTEM-8, SYSTEM-1, and SYSTEM-1m hardware synthesizers. This means you can work in your computer-based DAW or perform live without a computer using the exact same sounds. You can even send sounds back and forth between the hardware and software, and use the hardware as a hands-on controller.

*Although Roland has tested numerous configurations and has determined that on average, a computer system similar to that described above will permit normal operation of the PLUG-OUT SOFTWARE SYNTHESIZER, Roland cannot guarantee that a given computer can be used satisfactorily with the PLUG-OUT SOFTWARE SYNTHESIZER based solely on the fact that it meets the above requirements. This is because there are too many other variables that may influence the processing environment, including differences in motherboard design and the particular combination of other devices involved.
