"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."
"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!) 🙌 "
"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.
We have a new (and familiar) maker in town. :) Congrats to DivKid! I added a new DivKid maker label to the site. Don't miss the interview with BoBeats further below.
"**TIMING INDEX / SECTIONS BELOW** So here we have it, the FIRST DivKid Eurorack module. It's been a long journey (and and on / off casual one to start with) since I first drew up a rough idea and panel design for this years back but this super simple, but highly effective little module (if I do say so myself) is finally released! Now I'm not a circuit designer or manufacturer, which is why this took some time. But more recently I worked with Befaco to bring this to life so I'm proud to say that although this is a DivKid module the PCBs say "powered by Befaco" on them. There's tonnes of potential ways to patch and make use of this and nothing will make me happier than to see the module living in peoples systems for a long time. This is available as a DIY kit or PCB/panel as well as assembled. Check the link below for more information.
**CORRECTION** This is available as a FULL DIY KIT or PCB/Panel combo not a partial kit as I say at the end of the video.
"In case you missed the live stream at the time, made it but would like to watch again, or were even at the in person event itself and wish to relive the beer, pretzel and modulation good times... here's a fresh 4k HD edited version of the OCHD-OBER-FEST event that myself (DivKid), Instruo and Signal Sounds had back in October 2023 to launch the new ochd expander.
I've also just put up a new video with the case and patch that I set up for this event. This was filmed more long form and in detail when I got back home. It's a polyphonic, generative ambient piece that makes use of lots of ochd and it's expander. Check it out here // [below]

The patch that launched the OCHD EXPANDER // Polyphonic Generative Ambient Eurorack Modular
"Here we have a detailed run down of the patch that launched the expander. I brought this case and exact patch back from my journey up to Glasgow for the OCHD-OBER-FEST live event with Instruo in Signal Sounds. We launched the ochd expander at that event and this patch was my demo for that event. Note - you can check out the live event re uploaded and editing in 4k below.
This is patch is a 4 voice, polyphonic generative ambient piece that uses 4 wavetable oscillators into 4 VCAs for heavily modulated chordal sound sources. That is then tone, drive and level modulated before feeding two FX with a novel patch routing. It's highly dynamic, from near silent quiet sections to loud sections. All that dynamism comes from ochd and the ochd expander."
"I’m proud to present to you STEREO STRIP. My next module made in collaboration with Befaco. Stereo Strip is a stereo EQ, VCA, panner, distortion, mute & line level input and/or output interface for external gear.
Stereo Strip builds upon the well trodden paths of studio channel strips expanding them for musical and creative modular use with voltage control. Simply try swapping out simple VCAs for Stereo Strip to enhance your patches with EQ and voltage controlled panning. Or get creative and check out the patches below for highly shapeable distortion hacks, mind bending stereo ring modulation, CV routing, feedback waveshaping and more."
Divkid Stereo Strip - A Channel Strip For Eurorack
video upload by Patchwerks
"In this video Matthew (aka EZBOT) shares an overview and demo of the Divkid and Befaco collaboration, Stereo Strip.
Stereo Strip takes the idea of a channel strip and makes it modular. We hope that by bringing this long-established component of the audio engineering world into the Eurorack environment and by adding CV control over its key parameters that you will find new, creative ways to use it in your patches!
It features stereo inputs and outputs for audio or CV with EQ, voltage controlled panning, stereo VCA, performable mute and input/output level switching for Eurorack or line level uses. Abusing the input level switching allows for some musical, modulate-able and highly shapeable distortion sounds too.
Stereo Strip was designed to be a creative part of a modular patch. Creating
stereo images from mono sources, shaping and modulating existing stereo
images, synthesising stereo pseudo ring modulation, sweetening FX with EQ or drastically wave shaping your oscillators, creating send FX routings with benefits or it can simply be used as a channel strip at the end of chain in a patch.

The addition of line level gain boosting (for the input) or reduction (for the output)
allow it to work as a stereo input or output interface for external gear with the
advantage of the VCA, panning and the EQ to shape the sound. Experiment with
bringing external gear into the Eurorack format and then shape and modulate
those sounds them on the way in!
Try patching Stereo Strip anywhere you would place a VCA in a system and/or
explore its EQ and voltage controlled panning, which are rarer additions to the
sound sculpting options for the Eurorack format.

"Here’s a video with Eric Schlappi from Schlappi Engineering going through his Eurorack performance set up that was filmed as part of DivKid’s West Coast Adventure (playlist below) last year. We get a look at his two voice system, focussing on distortion and harmonic control and saturation and simple drum set up that allows him to perform on a relatively small modular set up.

DivKid's West Coast Adventure
"One of the first voices I heard when I started modular in 2018 was Ben DivKid Wilson's and it's been my goto channel for learning a new module ever since. The DivKid modules are simple, affordable and small, but offer something that wasn't there before they were released. I used them in almost all my patches, often off-screen or underexposed. In my first Ochd video (January 2020) it doesn't even show. With the release of the Ochd expander I realized how important these modules are for my case. This DivKid Show is a contribution to the contributions Ben already made to the modular community. For those who are new to modular it's cool to have all modules in one video (except Stereo Strip, I don't have it). The shots from his videos are used without kind permission but I am sure it's OK.
As always I am not affiliated with anyone or anything.
The opening music is an adapted remix of one of Ben's youtube music library tracks (empty moons of Jupiter), free for everyone to use on videos."
"The new ochd expander adds 16 outputs to ochd with 4 sections of different functions. We have unipolar outputs from full wave rectifiers, analogue diode logic giving 2 pairs of MAX/MIN outs, a cascading mixing trigger section for stochastic timings and a 4-bit DAC ladder section offering 4 flavours of slow noise stepped random patterns. It really is a mammoth addition of functions not just to ochd but to any Eurorack system.
The ochd expander was released as part of ØCHD-OBER-FEST an in-person event that was also live streamed. If you’d like to watch the event check that out here"
ØCHD-OBER-FEST (live event) with DivKid, Instruo & Signal Sounds // celebrate all things ochd!
"Launched in 2019 and designed in collaboration with Ben "DivKid" Wilson, the Instruō øchd has set a standard for compact and versatile modulation sources which can now be seen across thousands of eurorack systems.
The øchd's 8 analogue outputs can now be be tripled with a farther 16 unique control voltage sources by pairing it with the øchd expander ([ø] 4^2).
All outputs are derived from combinations of the 8 analogue triangle LFO cores to produce an extravagant range of variable voltages, triggers and 4x 4-Bit DAC based stepped random voltage sources which are best described as flavours of "slow noise".
Enhance your existing modulation capabilities immediately with this 4HP cluster of control voltage capabilities.
Note: øchd required, all cables included with expander"
"A quick overview of the Molten Motion Meter designed by myself and Befaco Modular. It's a visualiser of voltage and a seer of signals. It's a VU meter and CV attenuator, it can mix and offset and looks lovely in a rack.
"Join me to explore my first Eurorack module - it's a beautiful and exciting thing! Designed in collaboration with Befaco, and Manu will be joining me to talk about the process and how it all works. It's not complicated; it's a simple and useful module that I hope will bring joy to every modular user.
The module will become available to buy during the live stream in assembled and kit form. An overview video and DIY build video will appear after the live stream.
Divkid also has a video:"
Audio & CV VISUALISED I love a Eurorack utility! // Motion Meter (MTR) from Molten Modular & Befaco
video upload by DivKid
"Here we have the new Motion MTR Eurorack module from Molten Modular (Molten Music Technology, Robin Vincent) and Befaco. The Motion MTR is your classic modular synth utility provided attenuation, inversion, offset voltages and mixing with the addition of lots of blinking lights!
More than a pretty light show the LED rings work as a VU meter (audio mode) or CV monitor and show your input voltages so you can better trace a patch, track down that feedback getting out of hand, or simply stared at blinky lights because secretly we all want out modulars to look like Christmas tree. They look great and perform well as you’ll see in the video.

MOTION MTR
CV AND AUDIO UTILITY / REALTIME VISUALIZER
Motion MTR allow you to mix, attenuate and invert signals while having clear visual feedback of their levels.
Each channel can function as:
Audio level control with VU meter
CV attenuator with voltage meter
CV inverter with voltage meter
Each input is normalled to 10v, so you can
use each of them to generate fixed voltages.
Also, the outputs of channels 1 and 2 are summed into Out 3 to be used as a mixer.
Patch it wildly to make it work as an attenuverter with offset, as a mixer, a VU meter or a combination of them all!
This module is our first collaboration with Robin Vincent from Molten modular.
"DivKid teamed up with SSF to make the RND STEP module. We used the RND STEP to modulate parameters on both of the voice modules in this patch. The RND STEP is basically six noise generators going into six sample and holds with some clever normalization so you can generate six random modulations with one trigger.
In this patch we used the SSF Entity Percussion module to generate all of the drum sounds and the Noise Engineering Basimilus Iteritas Alter as a voice sequenced by the Make Noise 0-CTRL. The XAOC Batumi and ALM Pam's New Workout clock everything. We used the Future Sound Systems Gristleizer Filter to add some screeching resonance that can be switched in and out with the Afrorack and Ali Modular OR Switch. Everything is mixed together with the Endorphin.es Cockpit.

"All DivKid videos from my trip to Chicago, USA for Knobcon 2023"
Playlist:
1. 73-75 era Serge in the black panel 'Quasar' system // Prism Circuits at Knobcon 2023
Here we meet Sky from Prism Circuits who takes us through what he offers in the 4U Serge format, specifically taking us through his black panelled QUASAR system which uses classic 1973 - 1975 era Serge circuits.
2. Uncontrollable Rhythms from Moon Cycles and beyond // Pet Rock at Knobcon 2023
Here's Jonah from Pet Rock taking us through his sell out, sold at cost, first Eurorack module 'Pet Rock'. The module uses moon cycle data and random number generations to create two complimentary or drifting rhythms of varying step lengths and pattern densities. It's a fascinating concept that could lead to "good days and bad days" for your rhythms.
3. QV-L a POWERHOUSE of a Eurorack modulation source // Five12 at Knobcon 2023
Here's Jim Coker of Five12, of numerology and Vector fame, taking us through his new QV-L 'quad variable LFO'. It's a real powerhouse of a modulation module with 4 outputs, multiple clocking and frequency options, internal modulation, random generators, customisable control/performance options, syncing to the Vector sequencer for additional program changes and lots more.
4. NEW way to WAVETABLE! with Alias Zone & Osiris // Chris Meyer & ModBap at Knobcon 2023
Chris Meyer of Learning Modular & Alias Zone has A NEW WAY TO WAVETABLE!
Chris has been working on a new X and Y based wavetable systems that does two fascinating things, firstly it "samples" his whole large studio system while keeping that performable and responsive in the ModBap Modular Osiris and secondly he's using harmonics and interval sets to create morphing tunings within those sounds too.
This wavetable pack will be released for free through the ModBap site in the near future.
5. A Modular Approach to Eurorack Mixing with BARTENDER & BARBACK // After Later Audio at Knobcon 2023
Here we have several new modules from After Later Audio from Knobcon 2023. Lenny takes us through Bartender, Barback and Cast Iron which make up a new expandable, modular approach to Eurorack format mixing.
6. Simple solid clock sync! The Missing Link & ML:2 (Ableton Link) // Circuit Happy at Knobcon 2023
Giving the demo without any audio to listen to is a big move. A bold move made possible by rock solid behaviour from the devices from Circuit Happy. We have The Missing Link Junior and ML:2 Eurorack modules that are both Ableton Link enable devices for not just clock sync and reset but bar position aware behaviours for triggering and syncing to the patterns too. Impressive all round.
7. Better Spring Reverb! (with more filter features than your filter?) // Bubblesound at Knobcon 2023
It was great to meet David from Bubblesound at Knobcon 2023. I've been a long time user of his modules and he's consistently made quality modules over the years. The upcoming Spring Reverb module looks at Spring Reverb options in existence and aims to make them better, a fully featured SEM style multimode filter is on the module so you can really shape what's going into the physical spring, changing it's behaviour and sound. There's on board feedback which David is leaning into in this video too for more experimental patching.
"Hello and welcome to this video in which I go through more than 10 patches that break down how utilities work, how you can use them for audio and CV and how these things can improve your patches.
Whether it's patching your own compressor, precision pitch transposer, turning low pass gates into side chain ducking devices, adding controls to knob-less modules or looking to push the behaviours of other modules ... we've got you covered! These patches are applicable to a wide range of modules, so I hope you find plenty to take away and apply to your systems.
Today also marks the release of two new Apollo View Modular modules, there's 'IOU' that we'll focus on which is a take on the classic utility processes of attenuating, inversion, offset and amplification (with a DivKid requested twist!) There's also a high end dual headphone amplifier called 'CanCan'. Not only is that a nice headphone or output stage, it has a handy VU meter (eye candy!) and if you jam & play with others that's a great tool for dual headphone monitoring.

1. Øchd: Overview and Demo
Welcome to the Patchwerks video series! In this inaugural video of our series, our resident expert Matthew Piecora (aka EZBOT) demos the amazingly simple and musically powerful features from the new DivKid module øchd. Remember to like and subscribe, because we'll have more videos of great gear coming your way soon.
From DivKid:
This collaboration between DivKid and Instruo is a 4HP all analogue triangle LFO generator with 8 outputs. Each of the 8 outputs are free running and are musically tuned intervals, as opposed to synced or variable phase outputs from each other. A range of fast to slow outputs can be set to make any patch drift organically and beautifully, letting your modulation freely drift various parameters. There's a global rate control to go up into either lower audio rates on the fastest outputs, or glacially slow. A CV input with attenuverter allows for waveshaping via feedback patching, everything from log, lin or expo curves through to odd staircases waves and more. A negative voltage can reliably halt the circuit which gives 8 track and holds over the outputs.
In this video we patch the Earthquaker Devices Reverb: Afterneath into the Make Noise Rosie to take advantage of the mono to stereo send. Doing this allows us to patch a second audio output from the reflect send into the right input of the stereo return giving us a stereo reverb effect.
From Earthquaker:
The Afterneath Eurorack Module brings the Otherworldly sounds from the effects pedal world right into your modular synthesizer with an expanded feature set. The Afterneath module features one main audio input, one main audio output, an audio send and return for the Reflect feedback path, and nine controls. Four of the parameters are controllable via CV, and each has been equipped with a dedicated attenuverter to process the incoming CV. The Afterneath module has a completely analog dry signal path and a totally digital wet signal path.

"Perfect Circuit asked me if I'd like to take part in their 'artist picks' gear of the year video for the end of 2023. I said yes, while pondering what gear has brought me joy and lots of nice music making this year ... that bit of gear was the Intellijel Cascadia, which I love coupling with FX but for this particular bit of music making I went with the T Rex Replicator Junior.
A joyous, feature packed and versatile synthesizer and a wonder of lo fi tape delay, a great pairing! So I made the video for Perfect Circuit, made some music, made a patch breakdown and also made a PDF Patchbook outlining all sorts about the patch, alternative gear, mastering electronic music and more.

"Introducing dåpf, the first dedicated effects processor in the Instruō product line. The Instruō dåpf is a set of two analogue all-pass filters.
You might be asking yourself, “What is the point of a filter that passes everything?” All-pass filters don’t actually attenuate frequency amplitudes directly, but rather alter the phase relationship of frequencies across the spectrum. All-pass filter stages appear in the vast majority of voltage-controlled filter topologies as well as serving as a core building block within DSP.
The normalled I/O of dåpf allows for cascaded or independent use of the two all-pass filter circuits, offering everything from classic phase-shifting to psychoacoustic stereo enhancement and synthetic Doppler effect.
• Two parallel all-pass filters • Independent attenuverters for voltage control • 1-Pole/2-Pole configuration for left channel • Cascaded normalisation • Global 1 volt per octave tracking"
"This video is long... But the second half is very much optional expansion and deep dive into some theory of all-pass filters. The first few examples are much quicker, more practical examples of dåpf patched. Thanks for watching :)" ~Jason ---

Wow! I didn't know All Pass Filters could do this // 3 Patches with dapf from Instruo
video upload by DivKid
"I'm always striving to learn and explore with sound and music and dapf (the new Eurorack module from Instruo) certainly brought a big slap of school day into DivKid HQ. I was aware of all pass filters, getting past the funny idea that "all" frequencies pass (so what's the point?) and knowing they were use for phase shifts. What I didn't know is how core and important to filter topologies they were and how creatively useful they could be.
Some exploring later and here we are, with 3 patches that really show the power of phase manipulation. While dapf makes a fantastically chewy phaser FX unit I didn't expect it would be such a great stereo expander for a single VCO nor did I know I could be MUSICAL and totally analogue 3 operator FM/PM (like the digital Yamaha DX and Casio CZ phase/FM methods) synth."
"AtoVproject have come out swinging with a new, exciting and unique take on what you could think of as a 'complex oscillator'. It's an analogue design and signal path under digital control, which allows for a unique built in modulation section alongside an absolute festival of VCAs in the circuit offering LOTS of CV modulation options for harmonic control, TZFM and folding.
Each oscillator has 4 harmonics set an octave apart and each harmonic is its own triangle wave. These can be level (AM) modulated and used for TZFM (through zero FM) and all that goes into a mix section with external input into a wave folder. The wave folder is based on the circuit from the Befaco Chopping Kinky module (which I thought was a nice touch) with a redesigned VCA section.
The built in modulation is based on algorithmic noise which is used in video games to render things like mountain ranges, but there's also 10 LFOs you can use. Either modulation type can modulate any of the 10 destinations with the harmonic controls and FM levels.
Impressive stuff right? I'd love to know what you think ... leave a comment and lets chat about it!
p.s. it's available in the silver and black for the black panel brigade, or science lab chic crew.
"The Dual Harmonic Oscillator from AtoVproject is one hell of a sonic playground for all sorts of synthesis, sound and musical approaches to working with a dual or 'complex' oscillator. When I made the main demo (watch that first, link above) I ended up making so many patches with it that I wanted to put together a second video that revisited the module. So here it is."
EURORACK MODULE - RYO - Optodist Published on Apr 17, 2014 DivKidMusic·16 videos
RYO stand for Roll Your Own. I thought this was the first RYO post, but it looks like I had one last December here. Some info from the video follows. Click through the link for more modules by RYO.
"Here's my overview video for the RYO Optodist, voltage controlled distortion and saturating VCA. It passes both audio and CV so you can clip and modulate your control voltages as well as audio.
As always any questions ask in the comments or message me. Like the video and subscribe for more coming soon.
If there's anything you'd like to see from my set up let me know and I'll try and get a video together.
For more info on DivKid you can tweet @DivKid or go to our official site divkidmusic.com"
"A compact, easy to use, easy to build and great sounding distortion module which will also work as a VCA if desired.
The Optodist is based on two Silonex optocouplers that gives its characterful overdriven sound and plucky dynamic response to CV, it is equally at home adding a bit of extra crisp to highs and mids or warming up your lows as it is turning a resonant filter into a howling beast or your drums into crushing carnage. We offer two choices of optocouplers, SR2 and SR3, the latter giving a tighter, snappier CV response and slightly less bleed. Please note that due to the nature of the vactrol-style optocouplers, response behaviour may vary between different factory batches.
Also on board is an LED based limiter circuit which limits the signal thru a set of 4 LEDs which can be seen on the panel, for adding a different flavour to your distortion. Experimenting with different types will affect the sound.
The Optodist is a novice-friendly project, it is a low part count, single-PCB build that only requires the most basic experience in PCB soldering and module assembly. Kits comes supplied with PCB, front panel (PCB material), component kit, knobs, power cable and mounting screws. Solder and tools are not supplied."
"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!"
"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."

"Here we have what was my literal first patch with the Tempête Magnetique from Eowave. I really loved the Fluctuations Magnetique from Eowave and it was nice to see them build on that with the new module. While patching the filter I used a technique that I often do which is layering two sounds from a single oscillator into two filters with different modulation to get the sounds layered and dancing around each other. That technique is what we're exploring here.
