Roland releases PROMARS PLUG-OUT software synthesizer

Roland has announced the release of its PROMARS PLUG-OUT software synthesizer.


The PROMARS PLUG-OUT Software Synthesizer is a complete reproduction of the rare and powerful PROMARS synthesizer first released in 1979.

With two detunable VCOs and two sub-oscillators per voice, the PROMARS is easily one of the most deep and rich sounding monosynths ever created.

Designed for SYSTEM-1 as well as Mac and PC hosts, the new PROMARS uses Analog Circuit Behavior to faithfully recreate every detail of the incredibly warm, dense sound of the original, with a level of authenticity that can only come from Roland.


  • 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 PROMARS PLUG-OUT synthesizer is available for purchase for 110 EUR. A special price is available for SYSTEM-1 owners.
