ONEIROI is a full-stereo synthesizer that easily creates dense atmospheres for hypnotic music or cinematic sound design. Featuring three oscillators, four effects, a looper, modulation with complex routing, and a randomizer.

At the core of module, there is a Sine Wave Oscillator, Wavetable/Supersaw, and a joyful Looper. This is followed by an FX section featuring a Multimode filter, a Resonator, a Delay, and a Reverb. The on-board randomizer creates instant patches at the touch of a button. The Looper can record the external input or the output with “Sound On Sound” looping.
