"We're excited to share something we've been working on: Nodes, a modular FX plugin that just launched in early access.
Here's what makes it different: instead of being locked into a single effect chain, you get 55 nodes and counting—24 modulation sources and 29 effects—that you can wire together however you want. Sound design on steroids. We've also baked in our Eurorack LFO Lowstepper and mutable instruments modules, so the creative possibilities are basically endless.
The best part? It's a one-time purchase ($50 right now, down from $100). No subscriptions, no hidden costs. The price holds until version 1.0, when we're adding Linux support and more.
We built this for sound designers and producers who love tweaking, but the macro system makes it live-performance-friendly too. And because we're an active developer team that actually listens to community feedback, this thing is only going to get better.
It's CPU-efficient, works on Mac and PC now (Linux coming at 1.0), and honestly—you can build anything with it.

This demo takes Freqlux into a synth-based setup, using its tri-pitch engine to create movement, harmony, and new layers of sound beyond the usual pedalboard world.
NeonGlow was never made for one instrument.
It was made for ideas."
Pitch shifting, reimagined.
Freqlux is not just another pitch pedal. It is a creative engine built for players who hear more than one idea at a time. With three fully independent pitch voices and deep real-time control, Freqlux turns complex harmony concepts into playable reality.
Three Voices. Unlimited Directions.
At the core of Freqlux are three completely independent pitch engines. Each voice can run a different mode, interval, and behavior. Unlike traditional mono or standard poly pitch pedals, Freqlux lets you stack, blend, and sculpt three pitch ideas at once.
Each voice can be assigned to one of the following modes:
Poly Mode
Flawless polyphonic pitch shifting that preserves chord structure and articulation. Big chords stay intact. Fast passages stay clean.
Key Mode
Set a key and scale, and Freqlux generates musically intelligent harmonies that move with you. Classic harmony tones with modern precision.
early tests with Buchla Lightning + Max; once again, using a Buchla controller as a way of testing different parametric linkages / interaction strategies for what i hope will eventually become a standalone instrument. in this case, lightning is sending several position-related CCs to Max, which is running several simultaneous [gen~] patches. these patches were originally developed for several daisy-based modules i designed, namely:
2x Impulse Generator (a pulsar synthesis-based oscillator and nonlinear distortion feedback device)
1x Retention Mechanism (a granular sampler / multitap delay / pitch shifter)
1x Temporal Drag Processor (a multitap delay / resonator)
i only recently acquired the Lightning; here, i'm using it with the rings from a Buchla 222e Multidimensional Kinesthetic Input Port. the use here is quite basic, relying mostly on the Lightning "Ear's to MAX" factory configuration. no doubt i'll keep exploring more unusual ways to use it in the future
"The Djupviks Elektronik Grief Manual is a Neuron-based wavedestroyer, CV generator and chaos source. This is the full functionality walkthrough, covering every control and how the three internal circuits relate. A separate patch video is coming soon.
Grief Manual is a limited run of just 50 copies, each bundled with a vinyl LP. The module and the record share a theme of grief and loss. Unlike most Djupviks modules it ships pre-built rather than as a DIY kit, in the same spirit as the Bunker bundles.
At its core is a Neuron circuit based on Andrew Fitch's Non-Linear Circuits design, used here with Andrew's blessing. Around it Jonas has built a digital noise circuit related to the one in Mörser, a chaos and LFO circuit of his own design, and a square oscillator that doubles as a modulation source.
Everything interacts with everything else, so patching into it means intervening in a system that is already in motion.
Disclosure: Jonas sent me this module to keep. As always, my assessment of it is my own and entirely honest.

"This is a quick demo of the new Catalyst Audio Electroserf MiG Thruster vacuum tube noise generator module showing some of the sonic textures that it can produce.
The output of the Thruster goes to the MiG VCA module and then directly to the digital recorder with no external effects or modifications to the sound, other than a bit of resonance "crunch" added by the VCA near the end of the video.
The Catalyst Audio Electroserf modules are now available to purchase at quality synthesizer retailers."
"To demonstrate the character of the Glowing Orb stereo state variable filter a series of filter sweeps were recorded. The audio passed from the Glowing Orb, through a SideCar VCA, Instruo Cuir output module and then to a Sound Devices MixPre 6 field recorder. No additional audio processing has been carried out apart from level adjustment."
"Glowing Orb is a new vintage-voiced, Stereo State Variable Filter from WORNG Electronics. It takes the SSI2140 filter core (based on the SSM2040 filter which gives the Prophet 5 Rev 2 its big and beefy sound) and configures it in a -12dB/oct SVF circuit based on the Oberheim SEM design, combining characteristics of two of the best loved, best sounding vintage filters in a unique combination. Of course a module from WORNG Electronics has to include 21st century features like stereo operation, volt per octave tracking and a gain compensated drive circuit which enables an extraordinarily wide tonal palette.
At 10hp, Glowing Orb is perfect for any sized system large or small, and packs in just the controls you need to keep things compact while still being incredibly usable, with space around the controls designed for human fingers.
The module features stereo input, with normalling for mono to stereo operation if only the left input is patched. The stereo output switches between sweepable Low Pass/Notch/High Pass, and Band Pass filter slopes, on a single output pair to simplify patching.

Please meet the module I've been making with Befaco! 🟠 RANDOM8 is a random voltage generator designed bring a whole modular to life, in the smallest possible space. You get 8 independent random voltage generators, with dedicated per-channel looping buttons and attenuators, in just 8HP(!) It's what I've wished I could have in my live modular for a long time - a stupid amount of per-step modulation in a small space, yet you can control the looping instantly.
RANDOM8 is previewing at the Superbooth 2026 show in Berlin May 7-9 2026, and in dealer hands for sale on June 15th. Visit Befaco's tent at Z180 to give it a squiggle!
There is a limited batch to start with and more will follow. Thank you, M8s."
Xaoc Devices proudly debuts two new products at Superbooth 26: Skopje 1988 Dual Quantizer and Budapeszt 1972 Exploratory Stereophonic Spectral Lattice Network. Here is some information on the modules.
On the surface, Skopje is a seemingly simple compact (6HP) dual quantizer with two independent channels. However, some clever features coupled with high-precision A/D and D/A converters make it a complex (though extremely easy to use) compositional tool suitable for all kinds of musical outcomes. The user interface is similar to Zadar with frontpanel labels clearly indicating the features available for adjustment. No menu diving as the small OLED display is only used for selecting banks and scales. Each channel is able to quantize its input to a different scale from a different bank (up to 100 banks each containing up to a 100 scales - if you're deranged enough to need as many... ;-). Skopje stores its data on a regular microSD card. The module supports its own very simple scale format (a straghtforward TXT file you prepare on your computer), as well as any of the abundant SCALA files you throw at it. You can mix and match different scale format files in one bank. Various tuning systems and description formats supported. Microtonality galore! Our own scale programming system additionaly includes a few clever features, e.g., various voltage limiting settings. But there's more.
Got a lovely sounding VCO, but with volt/octave tracking leaving something to be desired? Skopje to the rescue - you can quickly calibrate any of its channels to fit your VCO like a glove for precise tracking! Other notable features include: glide, scale switching via triggers or CV (great as a performance/compositional tool with your own scales/note combinations), and transposition (including unquantized for vibrato).
Skopje is in production and will be available in June 2026.
PS Yes, this is a game of life screen saver on Skopje in one of the photos :-)
MAIN FEATURES: - dual quantizer with precision A/D & D/A converters - highly customizable - compatible with microtonal scales - OLED display for ease of use - up to 100 banks, each with up to 100 scales - VCO calibration feature - data stored on microSD card - SCALA file support - 6HP
Budapeszt is a stereo dual spectral processor built around the interference of resonant structures. It features two independently tunable comb-type filters with six distinct modes. Each filter has its own set of controls, with two separate triangle LFO's providing internal modulation (with free and synced operation, and an envelope follower mode on top). The real magic happens in the interference between two stereo filters though. The overlap of two resonant structures weaves a spectral lattice: a complex grid of peaks and voids. The final geometry of that lattice is determined by the relationship between the channels rather than by either one in isolation. To encourage experimentation and for even more sonic flexibility, multiple feedback paths are available, including cross-coupled feedback between the filters. There's also a feedback phase inversion switch for each filter.
Filter modes include delay-based, phase-based, and filterbank-based approaches to shaping the frequency domain. The first mode draws on a signal model inherited from Xaoc Devices Samarkanda, enabling artifact-free pitch behavior across the full frequency range. The remaining modes distribute resonant energy in ways ranging from the mathematically orderly to the perversely irregular. That being said, more familiar results, like flanging and chorus, are also easily attainable - delivered by Budapeszt with unusual precision.
Budapeszt is equally at ease processing oscillator waveforms and complex samples. It eagerly responds to short triggers with percussive transients whose character depends entirely on what the two channels are doing to each other. The interaction between the two channels is the instrument. Two channels agree, and the result is color. Two channels disagree, and the result is stormy weather. The space between agreement and disagreement is where Budapeszt lives.
"Superbooth is around the corner and I’m happy to finally unveil the prototype we’re going to show this year.
The Queen’s Court is a new kind of stereo matrix mixer, combining a fully analog signal path with deep digital control — and removing the need for external modulation. Designed for performance as much as for studio work, it brings hands-on control, internal modulation, and preset morphing into a single, cohesive instrument.
At its core, The Queen’s Court offers 4 stereo inputs (configurable as stereo or dual mono), 3 auxiliary stereo inputs, and 4 stereo outputs — all freely routable within a flexible matrix and it embeds modulation directly into the routing structure.
The Queen’s Court integrates 36 internal modulators directly into the matrix.
Per-input panning with LFO-based autopanning Per-routing-point bipolar envelopes, triggerable via CV or extracted from audio signals Integrated LFOs on each routing point, with sine and random waveforms, clock-syncable This enables advanced behaviors such as internal sidechaining, dynamic routing, and animated spatial movement — without relying on external modules.
Designed with an open-ended philosophy, The Queen’s Court can function as:
a self-contained matrix mixer a performance mixer a feedback processor a routing hub for audio and CV Oh and the system can also be expanded with up to two expanders, increasing the total to: 8 stereo inputs 5 auxiliary stereo inputs 4 outputs 8 CV inputs"
"Eddy is a three channel stereo CV controlled mixer with sidechaineable compression and distortion, designed as a compact submixer. It also has normalized feedback paths for more experimental tone shaping, no input mixing, and percussion synthesis workflows.
The Cascade expander allows access to the individual VCA outputs for use as a triple stereo VCA as well as access to the feedback filter outputs and simultaneous clean, compressed, and distorted bus outputs for additional mixing and processing options."

"A short update on the browser based Nord Modular Editor that I am currently working on as a fun hobby project."
Additional details via https://nordmodulareditor.com where you can try it out yourself if you own an original Nord Modular:
"Nord Modular G1 Editor
Create, edit and (soon) share your Nord Modular patches with the community.
Some quick remarks:
This is still a very early version. A lot of things don't work or don't work correctly yet. You should be able to edit patches, browse slots, add modules and cables, adjust parameters and load patches into a slot. You probably want to run this in the Chrome browser, i haven't tested others. I have only tested this with a Nord Modular Keys for now, I assume the Rack version will work the same but I don't know about the Micro. I assumed it would work the same but it appears that some people have issues getting it to connect. Parameter values are often shown as their raw 0–127 values. None of the displays work yet. When something is wrong, updates don't come through, or communication seems to be stuck: refresh the page. When using a trackpad, you probably want to use "scroll to pan" navigation. You can select this in the settings. To add a module, drag it from the toolbar on top. To delete a module or cable, select it and hit delete. The tab key in the editor will toggle rendering cables behind or in front of the modules. If you were following my personal YouTube channel for updates, please follow my other channel instead. Feedback is much appreciated, but I don't have a proper way to do that yet. This is a personal hobby project. I am not affiliated with or connected to Nord in any way. Peter van der Noord"

KONSTRUKT-8 is an expressive live performance instrument and sound design tool – plus a hands-on deep dive into electronic circuit design. Each of its eight DIY modules comes with a detailed build guide and can be explored on a breadboard first, letting you trace every circuit design decision before assembling the final instrument.
KONSTRUKT-8 includes four fully analog drum voices:
• Snare Drum. A burst of filtered transistor noise layered over a tuned resonator creates a crisp snap.
• Hi-Hat. Six dissonant square-wave oscillators are mixed, filtered, and overdriven to create metallic percussion.
• FM Drum. Two interacting oscillators form a versatile percussion voice capable of kicks, toms, bells, and cymbal-like sounds.
A four-channel drum sequencer lets you tap in rhythms that loop automatically. Under the hood, shift registers store the pattern as a circular sequence of binary data.
All voices feed into a four-channel mixer with per-channel FX sends and a master insert, allowing you to shape the entire beat with external effects or the built-in distortion and compressor.
Two effects modules complete the system: an analog bucket-brigade delay (BBD) with flanger and delay modes, plus a diode-based compressor with sidechain capability.

"GreyScale is a compact, self‑contained MIDI sequencer built entirely around the Raspberry Pi Pico (RP2040).
Its minimal hardware footprint hides a surprisingly deep generative engine, combining Euclidean rhythm generation, step sequencing, probability control, and evolving melodic behavior.
The clean GreyScale UI provides immediate visual feedback — step activity, Euclid parameters, probability states — all rendered on a crisp LCD. A joystick and four dedicated buttons offer fast, tactile control, keeping the workflow musical and instrument‑like rather than menu‑driven.
GreyScale runs completely standalone with standard MIDI output, making it an ideal partner for hardware synths, desktop modules, or DAW setups.
Designed for spontaneity and long‑form generative performance, it encourages exploration and rewards experimentation.
A small instrument with a refined feel, GreyScale blends DIY charm with a polished, modern sequencing experience."
About this Pack
This updated sample pack is composed entirely with Serge Modular Synthesizers — systems known not for emulating instruments, but for redefining how sound is shaped.
Included are raw noise textures, slowly morphing drones, and intricate one-shots captured through extensive patching with Random*Source Eurorack modules and classic Paperface 50 series panels.
Each sound reflects the chaotic elegance of analog voltages in motion. You’ll hear modulations that escape grid-bound sequencing, and timbral behaviors that emerge from complex feedback, slewing, and intermodulation — the kind of detail digital systems rarely capture convincingly.
Why Serge Matters
Serge Modular was designed in the 1970s by Serge Tcherepnin. It was created as an open-ended tool for sonic experimentation. Influenced by cybernetics and avant-garde composition, this system rejects musical hierarchies and embraces uncertainty.
In Serge, control voltages and audio signals are treated as equals. The circuits invite exploration through feedback, cross-modulation, and unpredictable interactions. Every patch is a process of discovery rather than reproduction.
This makes Serge a powerful choice for artists seeking sounds that are not pre-shaped or confined by rules. The textures you will find in this pack are unstable, alive, and deeply human.
After sculpting sound in space with The 3B, The 3FX explores the creation of sound spaces capable of transcending all your instruments.
ARCHITECTURE
The heart of The 3FX is built around three fully independent effect voices, each based on a coherent 8-module architecture:
Two delays per voice, usable in series or in parallel An advanced, progressive feedback path up to controlled self-oscillation An analog 12 dB/octave multimode VCF (BP, LP, HP) to optionally process the audio spectrum, both on the delay lines and on the dry signal Independent levels for the dry signal and each delay line A panorama control to position the voice within the stereo field. The stereo input signal is distributed across the three voices: left / left + right / right. A mono signal is distributed across all three voices. Each voice can be used alone, stacked or combined with the others to create textures impossible to achieve with a conventional delay.
Check with dealers on the right for availability and price.

3. Hello Alchemist ! Bastl Citadel synth engine rave to experimental - Stazma and Bastl Instruments
Alchemist is now EURORACK... into the CITADEL!!!!!
So here we go checking out how this synth engine will play out with his other citadel friend the Wave Bard in breakbeat torture mode.
Also a cool oportunity to play around the Diktaat from Mzourack to trigger both units in a performative way.
Citadel Alchemist is a patchable hybrid-synthesis based eurorack module that empowers you in discovering melodies and even harmonies despite being monophonic. Patch programmable sequencing via the control signals into the two PITCH MOD inputs opens up a world of melodic inspiration beyond classic arpeggios while staying in your preferred SCALE.
5 synthesis modes The Alchemist has a carefully tuned wide timbral range spanning across 5 synthesis modes (FILTER, FM, HYPERSINE, SUPERSAW and GLITCHNOISE) accessed by main TIMBRE sweep that is refined by the RATIO control.
The ENV macro knob affects different parts of the synth and sequencing engine to maximize musicality and it even lets you continually morph between the synthesis modes and access truly unique sounds. The timbral palette is further extended by the dual FX section which offers either a wide delay that will smear the arpeggios into echoed harmonies or a chorus-flanger-distortion-combfilter macro custom tuned for each synth mode. You can also access gliding rubber textures with the PITCH SLIDE macro that applies pitch envelope and portamento. You can customize its rhythms and scales with the web-based editor. Modulate anything All main parameters can be modulated and tightly sequenced by the surprisingly powerful CV and GATE pattern generator. Create groovy off-grid beats using the built-in LFO, which can be synced, reset, or left to run freely.
Here's what makes it different: instead of being locked into a single effect chain, you get 55 nodes and counting—24 modulation sources and 29 effects—that you can wire together however you want. Sound design on steroids. We've also baked in our Eurorack LFO Lowstepper and mutable instruments modules, so the creative possibilities are basically endless.
