Befaco Introduces Iroi Stereo Effects Processor Eurorack Module

video upload by Befacosynth

"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."

Press release follows:

"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."

Befaco - Pony VCF

video upload by Befacosynth

"Space-conscious lowpass filter and volume processor.
A combination of VCF + VCA + Mixer that lets you mix three different sound sources, and shape their tone, and levels in a breeze.
The Pony Filter is built around the SSI2144 FATKEYS™ Chip. Has the elegant sound of the classic transistor filter without the associated distortions, due to Dave Rossum’s 'improved ladder' topology."

Also see DivKid's video here, and mylarmelody's Molten Music Technology video here.

Befaco - Octaves VCO

video upload by Befacosynth

"A harsh and funky take of an additive Oscillator.
Pile up multiplications of your frequency to get a lo-fi-retro wall of squared sound!
You get six doubled frequency pulses, or octaves, with common PWM and volume control for each of them.
The output of each is cascaded to the next one, so you can either have one output with all frequencies or break the chain and get several sums and modulate each independently!"

Update: and video from Divkid directly below. Also see mylarmelodies' Molten Music Technology video here.

A harsh & funky take on an additive oscillator // Octaves VCO from Befaco

video upload by DivKid

"Here we have what Befaco say is "a harsh and funky take on an additive oscillator" as it has individual harmonics or partials and VCAs to modulate them. However the idea of harmonics here is replaced with 6 octaves of square waves. It's an analog design with a triangle core oscillator that through frequency doublers give 6 octaves to work with, each turned into squares that respond to PWM. An onboard mixer allows for blending these squares, you can break out into new tones with self patching, or make multi-layered wide frequency spanning voices from the individual outs."

Farbfilter and Stolperbeats in 7/8 time - Transistor Ladder Lowpass with Drive

video upload by Making Sound Machines

"For this one we channelled our inner Radiohead and made a beat with a 7/8 rhythm.

Come to @superboothberlin 11-13 May 2023 to chat to us and test our modules - we'll be in a beach tent together with all our friends @thisisnotrocketscience3942 @paultasbeeb @knobula6211 @apolloview9305 @vaskiembedded and Swampflux!! We are going to have a really good time and you are all invited to come and play!

Plus they are all debuting new modules we are really excited about!

In this video we are using #Farbfilter, an analog transistor ladder filter for Eurorack with a wicked overdrive stage and CV controlled resonance. We're still putting the finishing touches on this one, tweaking a resistor value here or there and taming the ranges a bit, but we love how it sounds already. A huge thankyou to @DivKid and @SynthDad for providing feedback on this one!

In this patch, #Stolperbeats is sending a MIDI sequence to the @WeAreElektron Model:Samples, playing Samples from the @GoldbabySamples Silverdrum Machinedrum pack for modelsamples. The bass is a PWM saw wave from Apollo View Modular's Allscillator complex VCO.

Both signals are filtered using the Farbfilter, with Stolperbeats sending a CV ramp to the filter cutoff of one lowpass filter and @Befacosynth Rampage being triggered to modulate the other. Enrica is controlling the offset for cutoff and attenuating the incoming resonance modulation. Kits will become available after Superbooth via our friends at @ThonkSynthDIY and @explodingshed5542.
