The ProMars Compuphonic was unique largely in part due to its introduction of microprocessor control, hence the term, "Compuphonic." It used an Intel 8048 processor to control the all-analog VCOs, VCAs, and VCFs. This also allowed it to store patches, making it one of the early few analog synthesizers that had patch memory.

The ProMars CompuPhonic has 10 preset sounds and 10 user programmable patches. The preset sounds include Bass, String, Clavi, Piano, Voice, Trombone, Sax, Trumpet, Synth I and Synth II. A very standard and well laid out set of knobs, sliders and edit controls give you the power to create some really cool sounds.

Designed as a partner to the polyphonic Jupiter-4, the ProMars is often considered a monophonic version of the Jupiter 4. However, whereas the Jupiter 4 had only one oscillator per voice, the ProMars features two oscillators (that can be de-tuned). Also found onboard are a nice VCF (filter) with its own ADSR, a typical VCA envelope section, a nice LFO and a pitch/mod wheel that can effect the LFO, VCF or VCA. It even has a noise generator. Nice wood end caps add to its vintage appeal as well. It has been used by Vangelis, Spandau Ballet, Add N To (X), Jethro Tull, and Depeche Mode.

This is one of the best monosynths out there, very versatile, capable of lots of different tones, very raw, unkempt and mistakably analogue sounds. Twin filter HP and LP..supreme LFO capable of FM effects....shares some architecture with the JP4 but with one very important difference..the Promars has twin VCO's! Also one of the very few vintage Monosynths to have patch memories. All told I'd take this over any of the SH series..
