Barcelona, February 2010.

Befaco says it was created in February 2010 in Barcelona as “an open hardware platform focusing on professional DIY musical hardware,” turning the earlier electronic, musical and artistic research of its members into instruments. The company does not name its founders on its website, and French Wikipedia, the only Wikipedia edition with an article on Befaco, describes it simply as an association for sound research and a maker of modules for modular synthesizers, created in February 2010 in Barcelona.

The earliest archived version of befaco.org, captured by the Wayback Machine in November 2010, was a Spanish-language site that greeted visitors with “Bienvenido Befaco!” and promised information on how to build your own electronic instruments and “noisy contraptions.” It listed weekend workshops for that November and December: a noise generator with a lag processor, an oscillator, a 30 dB-per-octave low-pass filter, a quad envelope generator based on the Buchla 281 complex function generator, a quad VCA and a ring modulator. The workshop, not the shop, was the starting point.

Befaco’s home has long been Hangar, the arts production centre in Barcelona’s Poblenou district, which lists Befaco as one of its “orbiting” collectives. Befaco credits Hangar and Barcelona City Hall for supporting the project. In May 2025 Hangar hosted a Befaco workshop to mark 15 years since its first building workshop at the centre. Hangar’s archive also records a Befaco–La Orquestra del Caos residency grant in 2016, whose holder researched new approaches to composing and performing live with analogue modular synthesizers.

Kits, Creative Commons and the workshop.

What sets Befaco apart is how it publishes. The company says its designs are released under a Creative Commons Attribution-NonCommercial-ShareAlike licence, so anyone can download schematics and assembly guides and make their own variations for personal and educational use; anyone planning a commercial derivative is asked to get in touch first. Its support form lists three formats for its modules: factory assembled, full kit and PCB set.

The workshops remain central. Befaco says it runs them regularly in Barcelona, Madrid, London and Berlin, and has taken them to Tokyo, Kyoto, Toronto, Montreal, Chicago, Frankfurt, Helsinki, Lyon, Stuttgart and Amsterdam. It describes them as a test bed, where every module built by a newcomer becomes feedback, and says the process has incubated “several new modular initiatives” run by other makers. Befaco also organises Modular Day Barcelona at Hangar, a makers’ fair with a DIY zone and concerts; Hangar listed the twelfth edition for 13 December 2025.

The catalogue is broad and mostly practical: the Even VCO, the Rampage dual ramp generator, the Kickall bass drum, the Muxlicer, mixers, attenuators and a spring reverb driver. Thirty-four Befaco designs exist as free virtual modules in the VCV Rack library, tagged there as hardware clones. Recent pieces are more ambitious. Synthtopia reported the Noise Plethora in December 2021, three digital noise generators feeding three analogue filters, priced at €254.10 as a kit or €356.95 assembled, and the Oneiroi in May 2024, a stereo ambient and drone voice built on the OWL mk3 platform and named after the bringers of dreams in Greek myth. In between came the Morphader of 2021, four CV-controlled crossfaders under a master fader, which Synthtopia listed at €250 assembled, with DIY options too.

Open source as identity.

Two of the seven are British. ALM Busy Circuits dates its start to 2012 and its first module, Pamela’s Workout; its founder, Matthew Allum, is named by retailers and FACT magazine, and its press releases are datelined London. Instruō Limited of Glasgow, Scotland, was incorporated in 2016 with Jason Lim as its director, Companies House records show, and Lim has presented its instruments in public, including at the SchneidersLaden shop in Berlin in 2019.

Two have their roots in Barcelona. Befaco says it was created in February 2010 as an open-hardware platform, publishing its designs under a Creative Commons licence; an archived version of its website credits the support of Hangar, a Barcelona arts production centre. Endorphin.es says it was founded in 2010 by Andreas Zhukovsky in Kyiv, Ukraine, registered as a company there in 2013 with Julia Bondar, and moved to Barcelona in 2016.

Two are American. Pittsburgh Modular says it was established in 2012 by Richard Nicol, though archived pages show it selling modules by 2010; it is based in Pittsburgh, Pennsylvania, where it says its Structure cases are built, tested and shipped. Qu-Bit Electronix says Andrew Ikenberry founded it in 2013 while a student at Berklee College of Music in Boston; it is now based in San Clemente, California, and says it keeps as much manufacturing as possible in-house.

Verbos Electronics crossed the Atlantic. Mark and Sonya Verbos launched its first five modules at the NAMM show in 2014, moved production into a New York workspace after six months of outsourcing, and relocated to Berlin in 2017; the company, now Verbos Electronics GmbH, says its modules are designed and assembled there.

This guide sets out what can be checked about each brand — who founded it, who owns it, and what it says about where its products are made — and marks clearly what rests only on the company’s own word.

A collective that became a manufacturer.

Befaco now presents itself as a Eurorack manufacturer as much as a collective. Its website and shop describe its instruments as “designed and assembled in Barcelona,” a claim the company makes and which we have not seen independently documented. Collaboration is a habit. For the FX Boy, announced before Superbooth 2023, each effect lives on a Game Boy cartridge, and Synthtopia reported that Befaco invited fellow makers, among them XOR Electronics and Tesseract, to design carts. The Oneiroi Pod case was designed with 4ms, the RANDOM8 random-voltage generator was a first collaboration with the synth YouTuber Mylar Melodies, and several modules carry the name of the modular YouTuber DivKid. Synthtopia quoted Befaco’s Manu Retamero on the 2021 Morphader crossfader. In September 2026 Befaco announced ARK, a 40HP sequencer, synthesizer and sampler priced at US$799 for release in late 2026. Even the hardware around the modules is now its own: the Befaco 7U Case, announced in 2023 with a 104HP frame and offered assembled or as a kit, with MIDI and USB built in, is described by the company as a slim unibody of black anodised aluminium.

There is no published brand book. Befaco’s visual identity lives on its panels and web pages, the company publishes no official colours or typeface, and we have not found a documented logo designer. What it does document, in detail, is how its instruments are built, which is its own kind of brand standard.

For a design guide, Befaco shows how openness can be the identity: a maker that gives its schematics away and still sells the kit. Compare Erica Synths, another European maker that sells DIY kits, and 4ms, its partner on the Oneiroi Pod. For this guide we use panel black, a kit-bag orange and solder grey with a grotesque sans, an unofficial interpretation; no product or logo is reproduced.
