The Roland Jupiter-4 software synthesizer will be available as a Roland Cloud plug-in or as a System-8 plug-out.

Roland announced the release of the Roland-4 software synthesizer emulation. Now, this recreation of the company’s first polyphonic synthesizer is the latest addition to the Legendary Series available on Roland Cloud. You can access the Roland-4 emulation as a DAW plug-in as a “plug-out” for the company’s System-8 synthesizer keyboard.

Roland said the recreation was possible thanks to their Analogue Circuit Behavior (ACB) technology. Essentially, through analyzing the behaviors of the original units, their uniqueness, and even their instabilities, Roland was able to bring the unit to the digital domain. But new features include new condition controls and a new circuit module that lets you manipulate the “character” of the synth poly to suit your taste and musical style.

Roland’s evolving Analog Circuit Behavior (ACB) 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 beloved quirks and instabilities, giving the JUPITER-4 software synthesizer a breathtakingly accurate sound that buzzes with a uniqueness.

Although the Roland-4 has emulations of the unique VCO, LFO and filter sections, some features have been improved. For example, the recreation has an extended oscillator range and sub-oscillator volume control, velocity sensitivity, adjustable noise, and an arpeggiator! And adding a new phaser, flanger, overdrive, reverb, and delay on top of the original instrument’s overall chorus gives us plenty of effects to play with.

The Roland-4 plugin has a resizable user interface like the majority of modern plugins. Moreover, it also supports VST3, AAX and AU plugin formats. Native M1 and M2 compatibility is also available.

With System-8 integration, you can control the plug-in through the keyboards panel or use the plug-out functionality. This feature turns the System-8 into a standalone eight-voice Jupiter-4 synth!
