Roland AIRA Compact S-1 Tweak Synthesizer, 4-Voice Polyphonic Synth, 64-Step Sequencer, 64 Patterns, Built-In Effects, USB-C, MIDI I/O (S-1)

The Roland AIRA Compact S-1 Tweak Synthesizer is a powerful and portable synthesizer inspired by the legendary Roland SH-101. It combines classic Roland sounds with modern synthesis, sequencing, and performance features in a compact design that is easy to take anywhere.

The S-1 features four-voice polyphony and offers multiple oscillator options, including square, saw, sub, and noise waveforms. Its hands-on controls allow you to shape sounds using the oscillator, filter, envelope, and LFO sections. Creative tools such as OSC Draw and OSC Chop let you create unique waveforms and explore experimental sounds.

For music creation, the S-1 includes a 64-step sequencer with 64 patterns, allowing you to record and edit melodies, rhythms, and sound changes. Motion recording, probability, sub steps, velocity, shuffle, and portamento provide additional ways to create dynamic sequences.

The S-1 also includes an arpeggiator, Step Loop function, D-Motion control, and built-in Roland effects such as chorus, delay, and reverb. With USB-C, MIDI I/O, and battery-powered operation, it can connect with computers, mobile devices, other AIRA Compact instruments, or larger MIDI setups.
