Pulsar Synthesis | A Microsound recipe by Curtis Roads

video upload by Cinematic Laboratory

"Before anything else I'd like to stress that this video was triggered by the Plume from Hieroglyphic, but doesn't feature it. It's NOT intended as click-bait, it's an educational video. If you took the bait, go watch DivKid [posted here] or Tom Churchill's walkthrough [posted here].

The concept is from Curtis Roads Microsound book. I read about the subject and tried to patch a few experiments with various results. Some good, some bad, and some turned out to be amazing. This video also fits my goals for 2024, where it's not always necessary to get yourself a new module when your existing modules still have plenty to offer. Happy patching!"

Patching a modular sequencer from basic building blocks

video upload by Tom Churchill

"This is a patch with two voices playing relatively complex complementary melodies - but I’m not using a dedicated sequencer module to drive them. Instead, I’ve patched up a sequencer from scratch using a couple of voltage-controlled switches, a couple of clock dividers, a matrix mixer and a quantiser. All I need to feed in are a simple steady clock and a fixed offset voltage, and I get loveliness out. Find out how in this video!"

Exploring pulsar synthesis with Hieroglyphic Plume

video upload by Tom Churchill

"Plume is the debut module from Hieroglyphic. It’s a digital oscillator based around pulsar synthesis, which is a fairly obscure technique devised by Curtis Roads in 2001, inspired by astronomical observations of neutron stars. In this video I build a few patches to explore the range of sounds it can produce - from complex stereo leads to West Coast-style wavefolded tones to rich, modulated drones.

Thanks to Hieroglyphic for supplying the module."

Xaoc Devices Berlin: the oscillator that opens up the Leibniz Binary Subsystem

video upload by Tom Churchill

"On the surface, Xaoc Devices Berlin is a simple compact VCO offering square and saw waves with hard sync, FM input and octave switching. The most interesting part lies behind the panel and that is the Leibniz Binary Subsystem interface, namely LBZ out and LBZ in. The frontpanel LBZ LINK button and its corresponding gate input switch between the default saw wave and a signal that has been passed through any Leibniz module (or a combination of Leibniz modules) connected to Berlin. Add Xaoc Devices Jena for wave processing and the output is no longer a simple saw wave – you now have a vintage-style wavetable oscillator with a penchant for the experimental due to its open, hackable nature. Berlin operates in a way similar to the classic PPG Wave and Fairlight CMI synths and employs a variable sample rate of an extremely widerange internal clock. As the sample rate changes with the oscillator frequency, Berlin's internal square and saw waves exhibit no aliasing effect. The whole frequency range spans from 30 seconds in LFO mode up to 250 kHz (!) with the clock reaching an astounding 20 MHz. Add to that voltage control over all parameters and the result is a highly versatile module capable of creating a significantly diverse palette of unusual waveforms.

Xaoc Devices Berlin notable features:

– wide-range VCO with LFO mode (over 20 octaves of tracking);
– Leibniz Binary Subsystem interface;
– extremely widerange clock source;
– manual and voltage control over all parameters (including octave switching and LBZ LINK!);
– simultaneous Square and Saw/Leibniz wave outputs;
– extensive waveshaping potential when combined with Xaoc Devices Leibniz Subsystem modules, e.g., Jena or Rostock"

Deep dive with the AtoVproject Dual Harmonic Oscillator

video upload by Tom Churchill

"At the end of last year I took delivery of the Dual Harmonic Oscillator, courtesy of AtoV Project. I did a ‘first patch’ type video a few weeks ago, but now that I’ve had a bit longer to get to know it, I wanted to do another video that explores it in a bit more depth. I’m glad I took my time, because this is a very deep oscillator. It’s quite different from any other VCO I’ve used, and it really rewards experimentation. I’ve been coaxing some amazing sounds and textures out of it, and in this video I break down seven patches."

5 kick drum patches with Shakmat Battering Ram

video upload by Tom Churchill

"Shakmat’s Battering Ram is a great-sounding kick drum module that I’ve been using for a few weeks now. It’s already made an appearance as a supporting player in my last couple of videos, but I wanted to do a demo where it’s front and centre, because it has some pretty cool tricks up its sleeve."

Cizzle: a killer Casio CZ-style voice from ALM / Busy Circuits

video upload by Tom Churchill

"Cizzle is a Eurorack synth voice from ALM Busy Circuits based around Phase Distortion synthesis, which Casio pioneered in their CZ series back in the 1980s.

It contains two digital oscillators that would typically be combined and used as one voice, but you can also use them independently. Each oscillator can produce four-note chords and has its own VCA, so all you need is an envelope or two to start using this as a complete voice.

Acid, pings & alien voices | Nekyia Circuits Root Locus VCF

video upload by Tom Churchill

"Root Locus is an analogue filter from Nekyia Circuits, a new manufacturer based in Greece. It’s a 12dB/octave multimode design that’s based on the classic Serge VCFQ - but it adds a couple of unique twists, like the two audio inputs with a voltage-controlled crossfader, and a variable mode output with CV input.

In this video, I explore some of the weird and wonderful things you can do with it. A lot of these techniques can be applied to other filters too - you might just need one or two extra modules in some cases - so as always, you’ll hopefully get some ideas you can apply to whatever you’re using."

via Nekyia Circuits

"Root Locus is an analog 12dB/octave multimode filter, based on the CGS512 VCFQ filter. It adds a dual input crossfading mixer with gain control and a variable mode output with cv control for sweeps between filter modes, aiming for an extensive tonal variety! It also features a Ping input that allows for an impressively wide variety of percussive sounds. The sub range switch makes it a very versatile CV filter too, able to filter control voltages as well as transforming it to an interesting quadrature LFO while in self oscillation."

The AtoVproject Dual Harmonic Oscillator is a monster!

video upload by Tom Churchill

"This is a rich, complex-sounding patch based around the Dual Harmonic Oscillator from AtoVproject. It’s a big, super-powerful module with two triangle-based VCOs that offer four octaves worth of harmonics, as well as regular sine, saw and pulse outputs via the expander. I’ll be covering it in more detail in a dedicated video soon, but in the meantime check out DivKid’s excellent deep dive if you want to know more about it: [posted here]

In this patch, it produces four melodic layers, with everything driven from a simple 8-step sequence out of the Jasmine & Olive Trees Traffic module switched over to the Water firmware. Joranalogue Filter 8 provides some quadrature LFO modulation to control the levels of the harmonics, and ALM Pamela’s Pro Workout provides clock, trigger patterns and transpose voltages. I’m also using the Nekyia Circuits Obsidian for some extra LFOs, and the Sosumi LPG on two voices - full video coming soon on all the Nekyia stuff, it’s great! Reverb is Valhalla Supermassive (in the box).

Exploring clocks, loops and chaos with Rung Divisions from Fancyyyyy Synthesis

video upload by Tom Churchill

"This video is about Rung Divisions, by Fancyyyyy Synthesis. It’s one of the most inspiring modules I’ve used recently, but it’s also quite a hard one to sum up in one sentence.

It has two main components. The first is a clock divider which outputs pulses that you can combine in two buses to create polyrhythmic patterns. That drives a universal shift register which outputs pseudo-random, chaotic or looping stepped voltage patterns. It’s an evolution of Rob Hordijk’s Rungler circuit, which is at the heart of the Benjolin synth. And there are dozens of interesting musical applications for it - a few of which I explore here.

Find out more at

NB: Fancyyyyy Synthesis sent me this unit to check out, but I don’t get any other sort of payment. This is a demo, not a review, and this channel is a hobby, not a job, so I only showcase things that I’m genuinely enthused about.

More stuff from me:

00:00 Intro and patch previews
02:46 Rung Divisions overview
05:54 Drum trigger sequencing
09:54 Melodies from pulse divisions
14:14 Shift register sequencing
20:15 2-channel pitch sequencing
24:00 Patching a voltage-controlled clock divider
27:42 Shift register as a VCO
30:22 Rungling for chaotic sequencing"

​Rung Divisions combines a universal shift register, a “divide by n” pulse divider, analogue noise, and several logic and binary operations. These functions synthesise an array of predictable and unpredictable digital signals at arbitrary time scale.

Rung Divisions’ primary use is as a complex polyrhythmic gate generator that drives a chaotic / pseudo random / looping stepped cv pattern generator, with voltage control over the pattern “direction”, length, and chance of the pattern looping. The combination of these features can be used to generate auditory illusions similar to a stroboscopic effect – like the visual aliasing of a wheel that appears to stand still and reverse direction at speed. Rung Divisions is built with solid state & discrete logic blocks to work at frequencies between 0–40kHz. The module is designed to drive multiple voices with gate patterns and CV, or to generate audio rate mayhem - these functions can be combined through patching with other modules that can take input signals over a wide frequency range. ​

Rung Divisions behaves in many surprising ways with feedback and self patching - the module has propagation delay compensation to allow for all outputs to be used in feedback loops.

Creative modular sampling patches | SebSongs Sampler

video upload by Tom Churchill

"This video is about the SebSongs Modular Sampler. It’s a new DIY kit available from Thonk, who kindly sent one over for me to check out. It’s a simple 12-bit mono sampler with about three and a half seconds of memory and a beautifully crunchy, lo-fi sound inspired by vintage machines like the Akai S612.

In this video, I’ve put together a small case with a few of my other favourite modules - the Blukac Endless Processor, the Serge VCFQ and Resonant EQ, the Pladask Dradd effects unit and the Xaoc Devices Sarajewo BBD delay - and I've built a few simple patches that explore some creative uses of sampling."

CHORUS EXPANDED! Stereo BBD Juno style Chorus for Eurorack // SoundForce Chorus 6 & µChorus 6

video upload by DivKid

"Here we have a video packed with audio examples of not only the Chorus 6 and µChorus 6 from SoundForce but lots of examples of how to use Chorus and how to expand on the basic uses.

This video includes lots of patches with the DivKid Community music and patches! I asked my Patreon supporters to send in their audio that they’d like to hear through these modules and they sent in a great range of audio, all credited below and in the timing index. Thank you for the general support and thank you for the great audio to work with.

The Chorus 6 and µChorus 6 are both based on the classic Roland Juno series synths and they feature the same audio path as those originals. It’s a stereo array of MN3009 BBDs with basic mode control on the micro version and more expanded fully featured LFO, CV control and externally modulated options of the larger module."

Xaoc Devices Rostock & Drezno II: new patch ideas for the Leibniz Binary Subsystem

video upload by Tom Churchill

"In this video, I’m taking another look at the Leibniz Binary Subsystem from Xaoc Devices. This is a set of Eurorack modules that let you convert analogue audio and CV into 8-bit digital signals and then process them in all sorts of unique and interesting ways. Using various combinations of Leibniz modules, you can do everything from waveshaping and bitcrushing to sequencing and drum pattern generation.

Xaoc Devices recently sent over the latest modules in the system for me to check out. Drezno II is a new and improved version of their original analogue to digital and digital to analogue converter module which acts as the main front-end for the system. And Rostock is a binary data pipeline, or digital shift register, which lets you delay, loop, scramble and reclock the 8-bit data stream. In the video, I build a few patches that explore some of the musical applications of these tools."

5 filter patch ideas featuring Plum Audio ADVA

video upload by Tom Churchill

"This video is all about some of the weird and wonderful things you can do with filters in a modular synth setup. The filter I’m using is ADVA, which Plum Audio kindly sent over for me to check out.

As you’ll see, it has some powerful features crammed in. But don’t worry, most of the patch ideas in the video can be achieved using other modules too, so hopefully you’ll get a few ideas for things to try no matter what gear you’re using.

Please note: Plum Audio supplied me with an ADVA module in exchange for this video. It’a demo, not a review - but do rest assured I only make videos about modules that I would genuinely recommend to others."

7 patch ideas for Joranalogue Delay 1, from chorus to kick drums

video upload by Tom Churchill

"This video is about Delay 1, which Joranalogue very kindly sent over from Belgium for me to check out.

It’s a super-high-quality analogue BBD design that specialises in very short delays, from 1 to 50 milliseconds. This turns it into something much more interesting than a conventional delay or echo effect, as well as opening up possibilities for Karplus-Strong synthesis.

In this video, I build some patches that explore the musical applications of Delay 1, from stereo chorus and comb filter to melodic voice and kick drum generator."

Replica Buchla 100 series modular synth: LA67 Mort’s Barge

video upload by Tom Churchill

"This video is about Mort’s Barge - a replica mini-system of five Buchla 100 series modules that were used by electronic music pioneer Morton Subotnick in the mid-1960s. I recently built the 4U DIY modules from LA67, and in this video I walk through the features and create a few patches that show what they’re capable of.

My build notes are here:

Find out more about the Mort’s Barge DIY set on the LA67 website:"

You can find additional posts featuring Mort's Barge here.

Notes and pics via Tom Churchill's post on Mod Wiggler:

"I thought I’d share a couple of things I learned along the way which maybe aren’t immediately obvious from the BOMs alone, in case anyone else is planning to tackle the build and is looking for some tips.

Some of this stuff has no doubt been covered earlier in the thread, so apologies for any repetition. Also, a lot will probably be obvious to experienced builders, but I’m definitely not in that category yet, so for anyone else (like me) who’s only built Eurorack kits previously, maybe isn’t super-familiar with circuit theory and component sourcing, it might be useful.

After I ordered the panels and PCBs from LA67 I contacted Julian at The Beast to ask about his 6U Buchla boats. As luck would have it he still had a couple of the special boats he supplied to LA67 for the pre-built Mort’s Barge systems, with matt black coating and pre-drilled holes for power inlet, power switch and grounding banana socket, so I snagged one.
I added some rubber feet to allow a bit of clearance for the screws I used to mount the PSU PCB (see below) and to avoid the underside getting scratched.
For mounting the modules, I bought a pack of 20 M3 speed fasteners (aka captive nuts, aka Tinnermans) from eBay, and secured the modules using M3 6mm screws with plastic washers.
The PSU PCB doesn’t require any caps and you just need to solder one bridge as marked. (This is now clear on the Mort’s Barge PSU BOM, but it wasn’t at first.)
I mounted the PSU PCB on 8mm M2.5 standoffs via the pre-drilled holes in the bottom of the boat.
I added a DC inlet and wired a 20mm round rocker switch in series.
I added a single banana socket connected to 0V to provide a ground for any other cases I might want to use with it (and for connecting to Eurorack - see below).
For the AC-DC converter I just used a standard 12V 2A wall wart I had lying around, with a 2.1mm centre positive barrel connector.
I used the 2-pin Molex connectors as per the BOM to distribute power to the individual modules (with the power cables hard-wired to the individual module PCBs)
Component sourcing:
I combined the individual BOMs for the five modules into one master BOM, ticked off what I already had in stock (mostly resistors), then ordered any other required resistors, trimmers, pots, 2N3904/6 transistors and various bits of hardware from Tayda; caps, specialist transistors, diodes, switches, knobs, lamps etc from Mouser.
I’m in the UK and banana sockets worked out slightly cheaper from Thonk, so I ordered those there. I also bought the necessary matched transistor pairs from Thonk to save time (I don’t have the tools or experience to match them myself!)
This might be sacrilege to Buchla purists but I went for Switchcraft 3.5mm sockets instead of Tini-Jax - I already have lots of 3.5mm patch cables and it makes for easier integration.
The 910p film caps on the BOM are huge - 10mm lead spacing - and expensive. I ordered them before I realised this, and with a bit of leg straightening/bending they do fit fine in the 158 and 180 boards, but I replaced them with these much smaller and cheaper 1n mylar film caps for the 140 - ... apacitor-5 - and they work just fine.
The BOM has since been corrected, but slightly annoyingly at the time I was ordering, the part code for the Dialight lamps in the 123 was out of date, so the ones that arrived in my original order were the wrong size. I had to do a separate order for the correct parts, 609-1122-130F. These aren’t cheap, so double check that you’re getting 9mm ones!
On the 158 BOM, there’s a suggestion to use 1n5 instead of 47n for C11 to reduce saw wave distortion. I put sockets in for that and tried both - the 1n5 definitely gives a much cleaner saw so I’ve stuck with that. I also left out C8 as suggested to improve sine shape - I didn’t try it with it included but the sine is definitely a good shape without so I’ll stick without it.
General tips:
I built them in the left to right order they’re shown on the LA67 photos - 158, 110, 180, 140, 123. It was pretty easy to test this way.
Calibration-wise there’s not much to do - the trimmers on the 158 adjust the sine shape and upper and lower frequency limits; use the 110 trimmers to minimise clicking with a raw trigger in; the 140 trimmers set the upper and lower period (I haven’t really touched these)
For the wiring, I soldered pins to the PCB and used a bunch of F-F Dupont jumper wires, cut in half, so if I ever need to take the board off I can simply pull these off and don’t need to desolder anything. For the multiple outputs I mostly just used old resistor legs to bridge them.
Integrating with Eurorack clock is easy - both the 180 and the 123 respond to triggers as low as 5V (e.g. from Pam’s). I don’t use a format jumbler, just a 3.5mm to two bananas cable, with the ground banana connected to the spare ground I fitted near the power switch. I don’t think I’ll ever bother trying to send CV from Eurorack but this way I can at least clock it to the rest of my system if I want to, and maybe even play around with some more complex rhythm patterns.
Anyway, hope that’s handy for someone - I’ll share a bunch of patches on YouTube soon!"

Xaoc Devices Odessa: full guide and fresh patch ideas using additive synthesis

video upload by Tom Churchill

"Odessa, by Xaoc Devices, is one of my favourite modular sound sources. At the time of recording, it’s been available for well over three years, but as far as I can see it’s still pretty much the only Eurorack voice of its type - a one-knob-per-function, five-voice paraphonic, digital additive oscillator - and I think it’s often still a bit misunderstood.

So I thought now might be a good time to take a fresh look at Odessa and see how it stacks up in 2023. If you’re an owner who hasn’t used it for a while, I hope it inspires you to dig in again, and either way, I hope you just enjoy some of the sounds and maybe learn a bit about additive synthesis in the process.

Note: I’ve done a few videos in collaboration with Xaoc Devices recently, but this isn’t one of them. I bought Odessa with my own hard-earned cash last year, so it’s not sponsored - I’m making this purely as a fanboy and I have no other agenda.

Make a Eurorack drum machine in minutes with Traffic by Jasmine & Olive Trees

video upload by Tom Churchill

"This video is about Traffic, by Jasmine & Olive Trees, a new maker from Barcelona. Traffic is a trigger-based CV controller that makes it really simple to set up three different drum or percussion sounds in a macro-oscillator like Mutable Instruments’ Plaits or Noise Engineering’s Basimilus Iteritas Alter, and then control them with individual triggers from a sequencer. But it’s definitely not limited to those modules, and in this video I’ll show you a few ways I’ve been using it with other sound sources.

This video isn’t sponsored; I bought the module myself and have no affiliation with Jasmine & Olive Trees. You can find out more about it at"

"Trigger-based CV controller with random modes.

Imagine having 3 triggers that will instantly set a BIA or Plaits as a kick, snare, and hi-hat. Using Traffic, you can effectively control multiple sounds from a single oscillator using triggers, much like a preset selector.

Traffic features 3 rows of 3 knobs, with each row having an output for the values of the knobs. You can select the active column of knobs using the trigger inputs. The three outputs are simultaneous, making Traffic a 3 channel controller or sequencer. Plus, the trigger sum output sends a trigger whenever there is a trigger in any of the inputs, ensuring seamless synchronization of triggers and CV values."
