Roland AIRA Compact S-1 Polyphonic Tweak Synthesizer

Roland's AIRA Compact S-1 is a revolutionary portable polysynth that puts an entire synth studio at your fingertips. Powered by Roland's acclaimed Analog Circuit Behavior technology, the S-1 lets you craft custom waveforms and add richness with overtones and comb filtering. The onboard 64-step sequencer provides endless options for crafting rhythms and melodies, with features like velocity, gate length and probability controls. Wearing multiple hats, the S-1 functions as a standalone synth for live performance, a sequencer for driving external gear and a MIDI controller for software synths.

ACB Engine Delivers Vintage Sound with Modern Flexibility

The heart of the S-1 is Roland's Analog Circuit Behavior synthesis engine, which authentically recreates the warm tones of vintage analog synths. ACB provides the S-1 with incredibly flexible and powerful sound design options not found on traditional analog synths. With OSC Drawing, you can draw your own waveforms on the color touchscreen. OSC Chop adds overtones and metallic resonances with overtone and comb filtering. The results are rich, dramatic sounds that are all your own.

Sequence and Perform Like Never Before

The S-1's 64-step sequencer opens up a world of rhythmic and melodic possibilities. Program velocity, gate length, sub-steps, motion recording and probability for experimental results. In D-Motion mode, you can manipulate a sequence in real time using the touchpad and knobs. The arpeggiator, with over 200 preset patterns, makes it easy to create pulsing synth lines. You can even transpose sequences and arpeggios on the fly for improvisation.

A Synth, Sequencer and MIDI Controller

Remarkably versatile, the S-1 serves multiple purposes for music creation. Use it as a standalone synth for live performance or in the studio. Employ the 64-step sequencer to drive external MIDI gear. In MIDI controller mode, the S-1 sends notes, program changes and control messages to software synths and more. A lithium-ion battery provides up to 4.5 hours of power for portable operation.
