Creative & Musical Uses of Precision Adders, Offset Voltages & Transposing // BEFACO VOLTIO

video upload by DivKid

"In this video we explore creative and musical uses of offset voltages and precision adders. Using the Befaco Voltio we explore creating chord intervals both statically and with offsetting musical sequences, we get creative with adding asymmetrical behaviours to waveshapers, we lock in FM ratios with analogue VCOs and plenty more.

The Befaco Voltio is a musical voltage source with 0-10V or -5/+5V octave offsets alongside semitone offsets, perfect for dealing in chord intervals. It features 2mm banana outputs that work with probes and it is a very accurate voltage that they designed for testing, building and calibrating modules. As well as generating voltages it's features a sum input, allowing this to work as a precision adder for adding or subtracting CV offset values from both sub audio CV signals and from audio sources."

Instruō - Befaco FX Boy - microPhaser cartridge | All-pass filter tutorial

video upload by Instruō

"Here's something a bit different!

Befaco (https://www.befaco.org/) have launched this very cool module which uses the "game boy" cartridge form factor as a means of hot swapping analogue and/or digital circuitry as effects processors.

I caught up with Manu and Diego at Superbooth23 and learned of this mad idea. I very quickly asked how I could get involved and contribute a cartridge design.

Time was a bit of a crunch.
I set the target of a month following return from Berlin as a timeframe for getting a cartridge production ready.
Challenge accepted!
I believe I had the first two (heavily circuit bent) prototype cartridges in the mail to Barcelona in just over a fortnight.
The last 5 minutes of this video shows a bit of this process designing the first prototypes.

The FX Boy ships with 7 carts in total designed by a wonderful range of creative developers.
I'm very excited to be part of this project.

This video goes through some of the capabilities of my microPhaser effect and ends with some behind the scenes recordings of the rapid development of the circuitry.

Cheers!

Befaco FX BOY // Gameboy based Eurorack FX with CV controlled EQ, Drives, Modulation, Delay & more!

video upload by DivKid

"Eurorack FX in Gameboy style cartridges that are hot swappable into a module with CV controlled parameters and a four band fully CV controlled EQ … YES PLEASE, WHAT A CONCEPT!

Beyond the obvious nostalgia hit of the Gameboy cartridges I’ve long been a fan of swappable FX platforms that allow a module to be used in a wider range of patches. FX BOY comes with 7 ‘founders pack’ cartridges with the Making Sound Machines Analog Wavefolder, FEEDBACK modules Flanger, XOR Electronics Delay & Granular FX, Instruo microPhaser, Befaco TRASH distortion, TouellSkouarn Noise & Feedback Fuzz and Tesseract Modular AVMA downsampled & ring modulator. It’s a wide range of FX all with two CV controlled parameters, plus CV over dry wet for parallel blends and modulation.

In this video I chose to give each cartridge it’s own patch, letting them shine on different patches with different use cases, as that’s how I’ll end up using the module going forward. However each cartridge easily warrants it’s own demo video going through a range of patches as these circuits have proven to be great on a range of sources. So I’m already thinking about future videos … leave a comment about what you’d like to see more of.

FX BOY is an open source platform for people to develop their own cartridge circuit FX, so who knows where this will go, whether Befaco release more cards, companies sell them on their own or whether it spawns some interest DIY ideas along the way."

Modular Day Barcelona 2023 after party - HRTL

video upload by Befacosynth

"There are few in the Czech electronic music culture with a background as storied as HRTL, the performing alias of Prague-based synthesiser musician Leoš Hort. Iconically performing from the centre of the dancefloor, HRTL is a force of the wildest nature on his instruments of choice, a carefully curated setup of modular synthesisers and tabletop instruments. Infamously electrifying and always improvised, each of his live club performances is quite literally one-of-a-kind; generative breakbeat rhythms meet with liquefying acid, and synths sliced from the utmost peaks of euphoria."

Befaco - FX Boy

"Happy and excited to be part of @modulardaybarcelona tomorrow - it's a super nice #modular #meet in Barcelona, Spain, with DIY #workshops, lots of great #synth makers and performances. We will be showing our #Stolperbeats drum trigger sequencer as well as the #Befaco FXboy, a #collab module between @Befacosynth @tesseractmodular3149 @MakingSoundMachines @touellskouarn6916 @xorelectronics @instruo and @feedbackmodules9902.

The module has a slot that takes cartridges in the same form factor as the @NintendoJP #gameboy, but with an #audio #effect circuit on it. This allows you to hot-swap #fx #circuits on you eurorack #modular #synth on the go, taking one cartridge out and replacing it with another as you jam. Our cart has an #analog #waveshaper on it, and provides you with #visual #feedback on the incoming CV with #colorful #LEDs shining through the translucent case.

Today's video is a little jam that happened when packing for Modular Day! Stolperbeats is seen here sequencing the #CycloneAnalogic TT-78, a drum machine inspired by the #classic #Roland CR-78 analog drum synth. The individual outputs are processed with the #FXboy, as well as our Farbhighpass transistor ladder highpass filter.

If you've been eyeing one of our #eurorack #DIY #kits and you want to build it together with us, Modular Day will be the the #perfect #opportunity! Hang out with us and build a Farbfolder, Farbshaper, Farbhighpass or TausenddB and Multiplikand with us.

Clank Thererec 2-channel eurorack cv motion recorder

video upload by John Schussler

Announcement post with pic here.

"There are quite a few cv recorders available in eurorack, including a few that use motion or pressure to indicate gestures. Clank has now released Thererec, which uses proximity sensors to sense your finger motions, and coupled that with recording functionality to loop your gestures.

The name is derived from its inspiration, the theremin, bonded to a recorder.

Where it gets more interesting is in the ability to change the range and speed of the looped gestures, plus a reset jack for syncing to a clock.

Source audio is a Befaco Pony VCO.

Eurorack cv presets - Traffic, Frames, Morphader, VC Transitions

video upload by John Schussler

"With the arrival of Traffic, a new module from Jasmine & Olive Trees, I find myself with several modules that do similar things around 'cv presets.'

The scenario I'm considering today is putting a single module (e.g. Basilimus Iteritas Alter from Noise Engineering) into different 'states' by simultaneously changing multiple cv inputs going to the module. This way you can get multiple 'instruments' out of a single module, in this case a variety of drums and percussion, which can then be sequenced.

There are other modules that do this as well (e.g. Endorphines Total Control), but these are the ones I happen to have. So, grain of salt and all that.

Sequencer is Pittsburgh Modular Micro Sequence. Clock source is Pam's Pro Workout.

Superbooth 2023: Befaco - FXBOY

video upload by sonicstate

"At Superbooth 2023, we spoke to Diego from Befaco about their new FX module, FXBoy. This module allows users to change effects via cartridges, which are designed by different manufacturers. These cartridges can be easily swapped out to change the effect on the fly. The distortions are analog, but some digital options are available as well. Effects Boy will come with a bundle of cartridges, but more may be released in the future.

Befaco is also presenting their new case, a 7U case with multiple connections, including USB hosts, USB devices, and MIDI. The inputs and outputs are color-coded, and the case features a web editor to customize outputs to be gates, oscillators, envelopes, and more. Befaco is preparing a 1U version without a display and the cases will come with a lid cover and are expected to be available at the end of June.

Befaco hopes to have FXBoy available in a couple of months for under $400."

Befaco Introduces the Fx Boy CV Controllable EQ Eurorack Module

via Befaco

"Following, our most special project till date: Fx Boy

Fx Boy is a 12 HP multi FX module with CV controllable EQ and Dry wet, with the peculiarity that each FX is built into a Gameboy cart! Yes, you read right, a Gameboy cart!!

And this is not just it, we have gathered a group of fellow Eurorack manufacturers to design a cart. So we will have 6 carts included in the module from: Feedback modules, Making sound Machines, Tesseract, Touel Skouarn, XOR electronics and Befaco!

It has been a great pleasure and BIG FUN to collaborate with these mega talented designers in these projects! You can expect old fashioned flangers, aggressive folders, dirty bitcrushers, fuzz galore and trashy distortions!

Module will be released in summer 2023 both assembled and DIY and pricing is still to be decided."
