Befaco Pony VCF Demo

video upload by Stazma

"Today I'll show you some fun patches with the new, small HP, all analog VFC by Befaco: the Pony VCF Don't be fooled by it's size, this little thing is a strong sounding 24dB/oct lowpass filter, but also a 3 channels mixer and VCA.
Great at both clean and dirty things."

Befaco's Octaves VCO Demo

"It's a very playful and 'retro' sounding oscillator in the sens that it's only square waves, so it will scream chiptune anthem instantly.

Have fun!"

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."

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!"

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."

A Eurorack Mix & Output Problem Solver // The NEW! Output Bus from DivKid & Befaco

video upload by DivKid

"Introducing the new OUTPUT BUS module from me (DivKid) and Befaco. It's an 8HP summing mixer, output stage, soft clip limiter, line level integrator, LED meter visualiser, headphone monitor and more ... it has many features that aimed to solve typical mix and output problems you'll find yourself working with in a Eurorack modular system."

A 5 minute rave on the Divkid Output Bus.

video upload by mylarmelodies

"Weirdly Ben has made almost exactly the module I need right now, as I'm building a modular mixer in my latest live system, and I need to sum and 'vibe up' the Roland TR-8. My pal Ben @DivKid sent me one for free - so here's me starting to use it! (Video update on this case coming soon!) 🙌 "

via DivKid

"The Output Bus is your ultimate output module: Presented by DivKid and Befaco, meant to be the last link in your modular chain!

Inspired by pro audio and studio summing units the Output Bus allows for summing style mixing, external gear integration, soft clip limiting, flexible output types, headphone monitoring and level visualization.

The module works great mixing all your other mixers in your setup, to return mono or stereo FX into the master bus and for bringing in external stereo line level gear with ease. All of this in just 8HP while also being able to visualize your final levels, output appropriate signals on the right cable type and monitor in headphones.

FEATURES

Six stereo inputs.

Line/synth selector in input six.

Modular level minijack out.

6,5” Jack balanced out.

3.5mm and 1/4″ headphone outs.

Led VU-meter.

Soft clipping circuit at main output."

Hot swapping FX circuits with the Befaco FX Boy // CAUTION - there's utter filth in here!

video upload by DivKid

"I really enjoyed making the FX Boy demo for Befaco and have enjoyed using the module since, so as further ideas for the FX Boy came to mind I decided to make FX Boy Fridays (anything for a catchy hashtag! #FxBoyFridays). For now this will be a pair of videos with some extra ideas, starting here with making one riff-y complex modular bass patch and drum beat thing and hot swapping the cards to see what they offer that sound. Short simple and there's some UTTER FILTH in there.

Fulsome FX Boy Demo, give it a watch //" [posted here]

Eurorack Phasers

volume 3 video upload by John Schussler

"I got a Pittsburgh Modular Toad not long ago, and realized I'd not compared the WMD Orion to anything either. Figured I'd put them both together, and throw in the G-Storm Polychrome to help join this video with earlier comparisons of eurorack phasers.

The Orion is now discontinued, and the Toad is a limited edition that will sell out. Only the Polychrome is in continued production. Not that there aren't other phasers, mind you, just saying if you like these....

VCO is a Befaco Pony. Little bit of reverb to make it not so harsh, but not too much. That's about it. Enjoy.

Eurorack Phasers - Take 2

video upload by John Schussler

"(This is a 'headphones required' video. You won't hear half of what's going on if you don't listen in headphones.)

This is my second attempt at a video on eurorack Phasers. The first (linked here but not otherwise listed in my channel: Eurorack Phasers) contained a number of mistakes. I'm keeping it around because I actually find those mistakes interesting, and want to be able to remind myself.

In particular, I didn't understand a couple things:

1) The SynthTech E560 input isn't set up for Eurorack levels, it's set up for line levels. If you don't attenuate the input, it distorts rather badly.
2) You have to use BOTH outputs of any module (that has them) if you want to hear stereo phasing. It's the contrast between the source audio and the phased audio that makes the effect, and you need two outputs to make that happen.

So. Once again into the breach, I attempt to compare some eurorack phasers. I think somewhat more successfully this time.

"Today i'll be showing you one of the most crazy eurorack module made last year: FX Boy by Befaco.
I'll be using it as an extension of the Doepfer Basic System 3, with it's little friend Voltio on as a sidekick, and I'll process EVERYTHING throught it, in order to create materials to then organise a little session in Ableton Live.

Have fun!"

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."
