Critic Reviews

Roland AIRA Compact S-1 Tweak Synthesizer

soundonsound.com

The Roland Aira Compact S-1 Tweak Synth offers a delightful sound experience reminiscent of its SH-101 predecessor, featuring impressive four-voice polyphony and a range of effects. The compact design is portable, and the unique Draw and Chop features allow for extensive waveform manipulation. However, the tiny keyboard can be challenging, and navigating the convoluted menu system can detract from the overall experience. While the synth shines in sound quality and versatility, its usability issues—like the lack of a clear undo function and the frustrating sequencer—may leave some players wanting more. For those who prioritize sound over convenience, the S-1 could be a valuable addition to their setup.
