Roland Cloud - 'PROMARS'
(Lifetime Key/Digital Download)

a reproduction of the rare and powerful PROMARS synthesizer
The Roland PROMARS was first designed as a younger brother to the JUPITER-4, the PROMARS compuphonic Synthesizer combines the stability and flexibility of microprocessor control with the beloved sound of analogue, resulting in a synth that provided incredible punch (2 oscillators per voice and a great-sounding filter) and impressive stage presence, 10 Preset and 10 User Patches- one of the first with memory. Nowadays we take programmability for granted, the influential sound of the PROMARS can only make a comeback with the power of ACB, and is now available as a fun software synthesizer on Roland Cloud!
The original PROMARS is often thought of as simply a monophonic version of the JUPITER-4. But the PROMARS was more than that. The JUPITER-4 had one VCO and one sub-OSC per voice, whereas the PROMARS had two of each. The pitch of the two VCOs could be detuned slightly to produce a unison chorus effect, and a sub-OSC was provided on each VCO. Capable of producing sounds close to a four-VCO synthesizer, the PROMARS sounded positively huge, and is practically the definition of a huge, fat synth tone. Although it isn’t as well known as the JUPITER-4, the thick sound and “compu-memory” function that allows sounds to be stored and recalled made it a highly regarded instrument with a unique place among the iconic Roland monosynths.
The PROMARS PLUG-OUT Synthesizer offers the sound of a rare, vintage instrument, perfectly reproduced with Analogue Circuit Behavior (ACB) technology. ACB faithfully captures the sound and feel of a renowned classic, using original design specs, and a detailed, part-by-part analysis of each analogue circuit. While the sound and behavior is reproduced with full accuracy, Roland improved 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. Just like Roland’s other PLUG-OUT synths, the PROMARS has great-sounding effects and an enhanced arpeggiator section.
