"A Shortcut for Atmospheric Processing
Iroi is a compact, 18 HP stereo effects powerhouse designed to turn any external signal into a deep, evolving soundscape. It inherits the sophisticated processing chain of its predecessor, Oneiroi. Combines a unique signal chain composed of a multimode filter, a VCA, a unique character resonator, a versatile delay, and an experimental Reverb. The filter - VCA act like a block that can be placed at any point on the signal chain"
Atmospheric FX Processing in Eurorack // IROI from BEFACO
video upload by DivKid and Befacosynth
"Here's Iroi from Befaco, which is the right hand side of Oneiroi standing alone at 18HP as a stereo atmospheric sound FX processor for Eurorack. There's improvements made and more processing headroom with Iroi and it offers stereo multimode filter, 3 band resonator, 2 tape delay and ambience reverb and reverse FX. Lots of CV, on board modulation and randomisation."

"BEFACO's NEW MODULE: IROI
The Oneiroi, in Greek mythology, were dark-winged spirits of the night who emerged to bring dreams and nightmares to mortals. Our ambient synthesizer, Oneiroi, takes its name from them, evoking that shifting, dreamlike realm of sound.
IROI is derived from 'Oneiroi' and carries that same essence forward, distilling it into something more compact and open to external signals, while preserving its cinematic feel that connects us to the world of dreams and the unknown.
What is IROI?
IROI is a stereo effects module based on the right half of the original Oneiroi. It applies Oneiroi’s sonic character to external sources in a more compact format, while incorporating subtle improvements developed throughout the Oneiroi project. Designed to shape, transform, and immerse sound, Iroi carries forward the dreamlike essence of its predecessor into a dedicated effects processor.
Audio Core: Powered by OWL mk3, featuring 24-bit 48 kHz stereo audio resolution (with 32-bit internal processing) and a full stereo signal path.
Filter: Multimode filter offering low-pass, band-pass, high-pass, and comb filtering, with flexible positioning within the effects chain.
Digital VCA.
Resonator: Three-band resonator with dedicated tune and feedback controls.
Delay: Two-tap echo (delay) with adjustable time and density.
Reverb: Comprehensive reverb effect with macro control over size, filtering, and direction.
Modulation: Various types of self-modulation, offering configurable routing and control over level and speed.
Control Voltage (CV): CV inputs for all primary parameters. Four of these inputs are dynamically assignable to secondary parameters.
Synchronization: External sync input supports clock speeds from 30 BPM to 300 BPM.
Randomization: Powerful randomizer with a flexible mapping system, including undo/redo functionality.
IROI is set to be released on April 30th, 2026 and the launching price will be 275€ (assembled version) and 210€ (DIY Kit).
Find us at Superbooth 2026, in BoothZ180 to see IROI live and take a peek at our upcoming products, we're pretty sure you'll love them."
