Roland Aira S-1 Tweak Synth

Divine a new world of sound with the S-1 Tweak Synth, a potent micro polysynth inspired by the legendary Roland SH-101. Jam with the snappy basses and expressive leads you’ve loved for years. Then launch your music into uncharted territory with futuristic wave manipulation, onboard sequencing, and unique performance features designed for modern creators. With its inspiring hands-on controls and intuitive workflow, the powerful S-1 delivers a fun and satisfying experience for beginners and serious synth adventurers alike

INSPIRED SEQUENCING.

The S-1 is primed to push classic SH tones into new dimensions. Build from square, saw, sub, and noise oscillators and mono, poly, unison, and chord modes. Or craft custom waveshapes on the step pads using the powerful OSC Draw function. OSC Chop unlocks even more harmonic potential, allowing you to cut waveforms into sections and explore a labyrinth of metallic timbres. Then top off your tones by using the noise oscillator as an independent riser to add sweeps and pulsing sound effects.

PERFORMANCE PLAYGROUND.

The S-1 is packed with features to inspire dynamic performances. Get physical with D-Motion to create compelling sound changes simply by moving the synth. Pop on the arpeggiator for cascading musical moments. Trigger the Step Loop function for live fills and on-the-fly rhythmic improv. And transpose patterns with just a few quick touches to instantly add harmonic richness to your jams.

Enhance your sonic palette with a wide selection of classic Roland effects. Add shimmering dimension with lush choruses derived from the iconic JUNO and JX-3P synths. Introduce spaciousness and movement with manual and tempo-synced delays. Then envelop your sounds with studio-grade reverb effects and a variety of adjustable parameters.

UNBOUND VERSATILITY.

The S-1 has all the connectivity you need to sync with your musical world. Link up with other AIRA Compacts like the T-8 Beat Machine, J-6 Chord Synthesizer, and E-4 Voice Tweaker to create a portable creative juggernaut. Interface with computer DAWS and mobile music apps via USB-C. Or use the S-1 and its MIDI I/O as a standalone sound module in a larger performance rig.

EVERYWHERE
AT ONCE.

The S-1 is ready to deliver instant inspiration anytime and anywhere. The lithium-ion battery provides up to 4.5 hours of runtime per charge, while the rugged Roland build will support you through years of musical journeys.
