Befaco is an Eurorack manufacturer that also offers DIY kits, organizes workshops and releases their designs under Creative Commons license.
In February 2010 Befaco was created as an open hardware platform focusing on professional DIY musical hardware, materializing the previous electronic, musical and artistic research of its members.
Our main activity has been developing synthesizer modules in eurorack
format and making them available in workshops. All this research is
published under CC-NC-SA License, so people can download the schematics,
and technical assembly guides, to make their own variations of the
projects for personal and educative purposes. Also build all our designs
during our regular workshops in cities as Barcelona, Madrid, London or
Berlin.
During the past twelve years, apart of these regular four
cities, we have visited cities as Tokyo, Kyoto, Toronto, Montreal,
Chicago, Frankfurt, Helsinki, Lyon, Stuttgart and Amsterdam, amongst
many other European cities.
These workshops are a huge test playground where we can track each module being built by different worldwide users, get direct feedback and quickly improve them with, develop new ones, or adapt these instruments to users demands constantly.
Direct contact with DIY enthusiasts allows an implication of users in the structure, allowing them to design their own modules and develop them in a professional way. This has developed into an incubation environment for several new modular initiatives, allowing different makers to start their own similar projects.
Befaco initiative is possible thanks to the support of Hangar, an artistic production centre in Barcelona, Barcelona city hall and the titanic work by the whole Befaco team.

Total flexibility for the Befaco 7U or Intellijel cases rear connectors jacks. The channels are reversible and can be used independently for input or output.4 Inputs or Outputs (per module) can be obtained by “AND” cables. Independent tip and ring attenuators are selectable for each channel to convert the modular input level to line output level.Features:• Selectable atenuator per channel.• Fully compatible with Intellijel’s 7U and Palette cases.• 1U Intellijel format.DIY-Kit-Type:SMD-Kit-2. This is a Do-It-Yourself kit, not an assembled module. The kit includes all parts to build the module. It includes SMD and through-hole parts!

This thing is totally awesome! Why? Imagine your plugins being controlled from your modular by CV! VCMC is a voltage-controlled MIDI controller. A fully editable MIDI controller with eight faders and push-buttons. Each of them with a CV or Gate input associated to automate their functioning via external signals or to be configured independently for further control. Each control on VCMC can be edited on its OLED screen and will be output either via DIN-5 or USB as a class-compliant MIDI device. DIYers can modify the module to make it standalone.Features:• Class-compliant USB MIDI and DIN5 connectors.• 10 CV inputs And 8 gate inputs.• 8 Faders and 8 Buttons.• Controls fully mappable to any MIDI message (CC, Notes, Program change, Clock, ST/SP, NRPN…)• Configurations saved both in internal memory and via Sysex.• Online Web EditorDIY-Kit-Type:THT-Kit-1.

RANDOM8 is an eight-channel random CV generator and looping voltage sequencer designed for improvisation, generative patching and live performance. Developed in collaboration with Mylar Melodies, it delivers random, repeating and slowly evolving control voltages in a compact 8HP Eurorack module.Each channel generates independent stepped or smoothed voltages from 0–10V. Incoming triggers are normalled between channels, allowing a single trigger source to control all eight outputs or additional triggers to create independent groups. Dedicated attenuators set the output range of each channel, while loop lengths from 1 to 32 steps make it easy to capture and repeat modulation phrases.A single button press switches a channel between looping and evolving operation. Pressing it again locks the current phrase, while a double press returns the channel to fully random generation. Per-channel probability, trigger division, offset and slide provide detailed control over the timing and movement of each voltage. Eight random generation modes include different voltage distributions, alternating high and low values, and wandering modulation that behaves like an invisible hand moving a control.The built-in pitch quantizer transforms any channel into a melodic sequencer, with 14 musical scales, an unquantized mode and a dedicated octave scale. RANDOM8 can generate eight melodies simultaneously or combine pitch sequencing with modulation, animation and LFO-style movement across an entire Eurorack system.Eight presets store the complete module configuration for quick recall, and the one-layer menu system keeps advanced functions accessible without a display.Features• Eight independent random, looping and evolving CV channels.• Adjustable loop lengths from 1 to 32 steps.• Per-channel pitch quantizer with 16 scale options.• Eight selectable random voltage generation modes.• Slide for smooth modulation, LFO shapes and acid-style sequences.• Per-channel probability, trigger divider and voltage offset.• Cascading normalled trigger inputs for grouped modulation.• Individual output attenuators and 0–10V unipolar outputs.• Eight presets for saving and recalling complete configurations.• USB-C firmware updates and free VCV Rack version.• Compact 8HP design with a depth of 30mm.• Power consumption: +12V 60mA, −12V 12mA.
