Experimental Synth Voice

According to Greek mythology, the Oneiroi are dark-winged creatures that emerge from their cave each night to deliver dreams and nightmares. With this module, Befaco has created a more practical way for you to receive their messages, even when awake.

What is Oneiroi?

Oneiroi is a live performance-oriented, multi-functional self-contained experimental digital synth focused on ambient pads and drone-like soundscapes.

It features a full stereo signal path, 3 oscillators (2 mutually exclusive), 4 effects, and a looper. It also includes self-modulation and a randomizer.

Oneiroi is based on Rebel Technology’s OWL platform.

Shape your performance

At its core, 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. It's 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.

The atmosphere creator

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 with four different targets thats  acts in different ways depending on the position of the two switches, three levels of intensity and undo/redo.

5-second Looper records either the stereo input or the module’s output, the Wavetable oscillator uses the Looper buffer
