Promars

Features

Designed first as a "kid brother" to the JUPITER-4, the Roland PROMARS Compuphonic Synthesizer married the stability and flexibility of microprocessor control with the awesome sound of analog. The result was a synth that offered incredible punch (2 oscillators per voice and a great-sounding filter) and outstanding stage presence (10 Preset and 10 User Patches- one of the first with memory!). While today we take programmability for granted, the inspiring sound of the PROMARS could only have returned through the power of ACB, and is now available as an incredibly-fun software synthesizer on Roland Cloud!

• Perfect replica of rare PROMARS COMPUPHONIC synthesizer
• ACB provides the rich, warm vintage tone of the original
• Two VCOs plus two sub-oscillators per voice
• Fast envelopes and filters with classic Roland character
• VST, AU and PLUG-OUT compatible

The original PROMARS was a sibling of the legendary JUPITER-4, and is often thought of as simply a monophonic version. But the PROMARS was more than that. While the JUPITER-4 had one VCO and one sub-OSC per voice, the PROMARS had two of each. The pitch of the two VCOs could be slightly detuned to produce a unison chorus effect, and a sub-OSC was provided on each VCO. Able to produce sounds similar to a four-VCO synthesizer, the PROMARS sounded positively huge , and is practically the definition of big, fat synth tone. While not as well known as the JUPITER-4, the thick sound and “compu-memory” function that allowed sounds to be stored and recalled made it a highly regarded instrument with a unique place among the classic Roland monosynths.

With the new PROMARS PLUG-OUT Synthesizer, the sound of this rare, vintage instrument is perfectly reproduced with Analog Circuit Behavior (ACB) technology. ACB faithfully captures the sound and feel of our most revered classics, using original design specs, and a detailed, part-by-part analysis of each analog circuit. While the sound and behavior is reproduced with total accuracy, we couldn't help but improve a few things in this new version. The VCOs have increased range settings, the LFO has a “Random” waveform setting, and the Noise and and Pulse Width sections have full range control of those parameters. And like our other PLUG-OUT synths, the PROMARS has great-sounding effects and an advanced arpeggiator section.
