To celebrate the 45th anniversary of the JUPITER-8, Roland introduces a miniature synthesizer with sonic capabilities and interface features inspired by the early-’80s legend.

Housed in the popular Roland Boutique format, the JUPITER-08 is a powerful and fun instrument that delivers classic sound, hands-on control, and modern performance tools in a highly mobile design.

The JUPITER-08 is perfect for synth collectors, electronic musicians, producers, and performers looking for the iconic JUPITER polysynth experience in a compact instrument for studio creation and live performance.

JUPITER SOUND, MODERN ENHANCEMENTS
Backed by Roland’s latest technologies, the JUPITER-08’s refined voice allocation and pitch
behavior deliver a rich, animated playing experience with enhanced polyphonic performance and genuine vintage-inspired character.

Maximum Creative Power
While previous Roland Boutique models had trimmed-down polyphony, the JUPITER-08 offers the complete eight-voice/two-part architecture of the mighty JUPITER-8. Players can access the same layered, split, and dual-part capabilities as the original, making this mini synth a highly capable tool for performance and composition.

Polyphonic Sequencer and Arpeggiator
Create basslines, chords, and melodic sequences with a two-part, 64-step polyphonic sequencer that supports up to eight notes per step plus motion recording. There’s also an arpeggio function for crafting dynamic, evolving sounds on the fly.

Expanded Effects Processing
The JUPITER-08 features powerful onboard processing for extensive sound shaping and spatial enhancement. Players can tap into 17 unique effects — including chorus and MFX—plus dedicated delay, reverb, and a new shimmer reverb.

Performance-Oriented Workflow
Dedicated controls, Hold functionality, and an intuitive interface provide immediate hands-on interaction in both studio and live environments.

Modern Connectivity
USB-C audio/MIDI interface, traditional MIDI I/O, and an external clock input make the JUPITER-08 easy to integrate into any contemporary production environment.

Compact Roland Boutique Design
The JUPITER-08 carries on all the great design features of the Roland Boutique series, including built-in speakers and flexible battery/USB-C power for music creation on the move. A K-25m keyboard dock is included, creating a standalone mini-instrument that’s ready to travel everywhere.
