The JUPITER-4 Software Synthesizer faithfully captures the essence of the original 1978 Roland JUPITER-4, a landmark in analog polyphonic synthesis. Known for its warm and rich tonal quality, this instrument delivers the classic sounds that shaped synth pop, new wave, and other influential music genres of that era. This software version brings the iconic analog character directly into digital music production environments, allowing musicians to access and recreate vintage textures with ease.

Enhanced with modern technology, the JUPITER-4 offers an intuitive, high-definition interface that mimics the look and feel of the original hardware while providing expanded creative potential. Users benefit from increased polyphony, adjustable between two and eight notes, and a Circuit Mod function that enables live tweaking of the sound’s character. Additional features include an advanced arpeggiator, built-in effects such as chorus, reverb, flanger, delay, and overdrive, along with extended parameters that open new sonic possibilities beyond the original instrument’s capabilities.

This software synthesizer is compatible with VST3, AU, and AAX formats and supports Apple silicon natively, ensuring seamless integration into various digital audio workstations. It includes all the original JUPITER-4 patches plus new sounds tailored for modern music production, and it can be used in conjunction with Roland’s SYSTEM-8 hardware via PLUG-OUT compatibility. The integrated browser makes it easy to explore and manage sound libraries, making this a powerful tool for both studio and live performance settings.
