Roland’s Jupiter-4 Software Synthesizer is the latest addition to the instrument series available through Roland Cloud. Released in 1978, the Jupiter-4 was Roland’s first polyphonic synthesizer and the first to carry the Jupiter name. With the Jupiter-4 Software Synthesizer, the authentic sound of this synth is now available as a computer-based plugin and a plug-out for the System-8 synthesizer keyboard. Roland’s evolving Analog Circuit Behavior technology brings the Jupiter-4 to life through careful analysis of original hardware units, circuit diagrams and other historical data. This information is then used to recreate the authentic circuit behaviors of the vintage instrument, including all the quirks and instabilities, giving the Jupiter-4 Software Synthesizer an accurate sound that buzzes with character.
