Incorporating a flexible design that allows it to used as a rackmounted, tabletop, or Eurorack synth, the Aira SYSTEM-1m Semi-Modular PLUG-OUT Synthesizer from Roland can function as a standalone instrument, provide CV/Gate signals for other synths and effects, and employs Roland’s PLUG-OUT technology that allow you to use it to control DAW-based software synths or install classic synth emulations directly into it.

The synth features 2 oscillators, with 6 waveforms each. A sync-able LFO allows you to create time-based wobbles and other effects, while further sound-shaping control is provided via the pitch, filter, amp, and EFX sections. Eurorack screws, along with a Eurorack power cable are included, along with a standard AC power cable, rackmount adapters, and 3 patch cables.
