Authentic ACB Polyphonic Engine

Powered by Roland's acclaimed Analog Circuit Behavior (ACB) technology, the S-1 delivers the iconic sound and response of the vintage SH-101 monosynth, expanded into a four-voice polyphonic engine. This allows for the creation of rich pads, classic basses, and sharp leads with authentic analog character. Go beyond emulation with modern sound-shaping tools for a truly unique sonic palette.

Ultra-Portable and Battery-Powered

Create and perform anywhere thanks to a compact, rugged design and a built-in lithium-ion battery providing up to 4.5 hours of operation. The S-1 is the ultimate travel-friendly synth, ready for impromptu jam sessions, mobile production, or integrating into a larger live rig. Power and recharge easily via a standard USB-C connection.

Advanced Sequencer and Performance Tools

Bring your ideas to life with a comprehensive 64-step sequencer and a host of performance features. Manipulate sounds in real-time by physically moving the synth with D-Motion control, or craft intricate melodic lines with the arpeggiator. The sequencer offers deep control, including motion recording and probability, for evolving, dynamic patterns.
