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
