"Burg is a great way to start with modular synthesis and plugging in patchcables ;) It provides you with all necessary tools to start your modular journey now. It is a standalone synth voice, complex multi FX processor, controller for external gear or all at once. The perfect companion to any setup, if you already have modular stuff, wanna connect with instruments or other gear. It can work for many different musical approaches and creative processes, it bridges between the analog modular world and external gear. The unique combination of circuits let you customize your desired sound in all analogue ways.
18 individual and characterful modules allow you to explore beautiful and weird interactions. You can easily create dynamic melodies, harmonic drones, weird noises and outer space sound effects. If you plug-in an instrument, a microphone, your favorite tunes or the internal sounds, it is easy to modulate any signal with a crispy filter (wasp-style), a wavefolder, some heavy distortion and a double delay to glitch your mind away. With 55 patching points in total, possible combinations are almost endless. The intuitive touchpad interface gives easy control over multiple CV and gate signals at the same time and is the main modulation source of the Burg system.
Two light dependent controllers guarantee a unique behavior and can be modified easily according to your needs or for experiments. Also other modules can be modified by exchanging components on the back plate, so customizing the frequency range of the oscillators/LFOs or shaping your individual clipping distortion with different types of diodes is possible.
There are two power bus connectors on the backplate so Burg can be used as a power supply for other eurorack modules as well. The internal power supply can be powered with USB-C (barrel jack) from 9V to 18V (center positive) and can work as a power supply for small modular racks using a flying bus cable."

This is a pre-release preview with automation-heavy settings and sequenced randomization firing at different musical divisions, so the “codec decay” breathes and glitches in time. Expect swish, birdies, smear, framey wobble, and the occasional moment where reality briefly loses its license.

Been working on this for a while and it's finally at a point where I want to share it.
*Tresse* is a standalone polyphonic synthesizer built around Mutable Instruments' Plaits DSP code, running on an ESP32-S3 with a custom PCB. Three voices of polyphony, 38 synthesis engines, USB, DIN/TRS and Bluetooth MIDI, and perhaps Ableton Link and our upcoming stack (VMB) Våld Modular Bus, expected to ship this summer, and which will a new wireless comms protocol with negligible latency, auto discovery and machine mesh capabilities (to be released soon). Also enough knobs and encoders to actually play the thing without menu-diving, and a battery for when you're bored outside of your studio.
*The core idea:* take the full Plaits engine library — all 24 algorithms — and make it polyphonic in a self-contained hardware instrument. Then keep going and add 14 more custom engines on top. There are hundreds of options similar to this in modular systems and i thought why not bring all these god-level creative tools to bedroom, desktop producers who don't have the money or the space (or will) to mingle in the modular space, and bring them one contained box with all they need.
What's inside
*ESP32-S3* doing all the DSP across both cores (voices 0+1 on Core 1, voice 2 on Core 0, parallel render) **PCM5102A DAC**, 24-bit output, 32kHz sample rate *4 pots + 4 rotary encoders* through CD74HC4067 mux and MCP23017 I2C expander *OLED display* (128×64) for patch info, engine select, preset browsing *USB MIDI + BLE MIDI* — works with everything, no adapter needed for wireless Custom PCB, all through-hole friendly
38 engines
The first 24 are straight from Plaits — East Coast, Phase Distortion, all three DX7 variants, Terrain, String/Chords, Chiptune, Wavetable, Speech, Swarm, Particle, the Rings modes, the three drum engines, etc.
Then 14 custom engines built from scratch:
*Karplus-Strong* — proper physical string modeling with excitation morphing (noise → impulse → tonal) *ByteBeat* — 8 classic formulas with pitch-tracked rate, gets wild *CZ Phase Distortion* — Casio CZ-style, three distortion shapes *Supersaw* — up to 7 detuned saws with PWM, the obvious one but it needed to exist *Formant* — vowel synthesis with 3 bandpass resonators, gender shift control *2-Op FM* — clean FM with 13 ratios and operator feedback *Wavefolder* — sine/tri/saw/square source into a proper folder with bias *Noise Drums* — SVF-based with pitch envelope, covers kicks through metallic hits *Modal Resonator* — 8 tuned bandpass partials, morphs from harmonic → bell → bar inharmonicity, with a bowed excitation mode *Sympathetic Strings* — 3 coupled Karplus delay lines with controllable coupling and interval ratios *Comb Resonator* — 4 parallel comb filters with spread control *Drawbars* — organ-style additive with 8 Hammond-ratio partials *Complex Oscillator* — FM into wavefolder, Buchla-adjacent territory *Grain Noise* — granular noise with smoothing, good for textures and pads
Controls
Three parameter layers accessible via toggle buttons:
*Normal* — Timbre, Morph, Harmonics, Color on pots; Attack, Decay, FM, LFO Depth on encoders *MOD* — Fold, Detune, Ring Mod, Chorus on pots; LFO destination/shape/speed/sync on encoders *SHIFT* — Filter Cutoff/Reso/Env/Type on pots; Portamento, Octave, Vibrato depth/speed on encoders
Hold both buttons → engine select overlay. Double-tap MOD → system menu (randomizer, MIDI config, play mode). Double-tap SHIFT → preset browser across three banks (own patches, generated, branches).
Play modes: Poly, Mono, and chord modes (Major, Minor, 7th, Sus4, Power, Octave).
The randomizer is one of my favorite things — it generates random patches with procedural names (stuff like "Velvet Moth" or "Iron Shard"), you scroll through them with the encoder, and save the ones you like to a generated preset bank. 512 slots each for generated and branch presets, 128 for your own.
What it sounds like
Honestly covers a lot of ground. The Plaits engines already span everything from classic analog to FM to physical modeling to noise, and the custom engines fill in some gaps I wanted — proper supersaw, real Karplus-Strong, the modal/sympathetic stuff for metallic and evolving tones, and the ByteBeat engine for when you want to go full chaos. The global FX chain (filter, wavefolder, ring mod, chorus) ties everything together.
The project should be available from April 2026, in kit or assembled units! Price to be discolsed once i have the final FINAL prototype, but shouldn't hurt the wallet.
This is a *Våld Labs* project from Lisbon Portugal. Much more to come.
Would love to hear what people think, and happy to answer questions about the build or the DSP. Be aware that this is a pretty advenced prototype, but still a prototype"
"Introducing my second sequencer for the Disting NT: Tintinnalogia. This Lua script (written with Claude) is an implementation of 'change ringing.' Invented in 17C England, change ringing is essentially a procedure for ringing church bells. It’s an early example of algorithmic composition, and is also proto-minimalist in its emphasis on a fixed, deterministic process. So...perfect for music-making on the modular!
All Tintinnalogia needs is a sample player with multiple trigger inputs: eg ALM Squid Salmple, Bitbox, or Disting’s own Sample Player.
Random thought: if the number of bells could be increased to 12, the script could be a twelve-tone serialism machine!
Katherine Hunt, 'The Art of Changes: Bell-Ringing, Anagrams, and the Culture of Combination in Seventeenth-Century England,' Journal of Medieval and Early Modern Studies (2018): connects change ringing to 'mathematical recreations' and to Early Modern ars combinatoria such as anagrams. If there was a meaning to change ringing, it was the 'exhaustion of meaning.'
Margaret Aston, Broken Idols of the English Reformation (2015): specifically, the chapter on bells.
Robert Adam Hill, 'The Reformation of the Bells in Early Modern England' (PhD thesis, 2012): dispels the assumption that bells lost their earlier, sacred meanings in the era of change ringing.
Brian Eno, 'Bells and their History,' Sound Unbound: Sampling Digital Music and Culture, ed. Paul D. Miller (2008). 'The same supply of metal would be made into cannon in wartime and would go back to bells after hostilities were over'
Ambient Engine is designed not just for 'making songs' but as a 'device that continuously generates sound.'

This one is in via GreyScale aka plantssystem whose videos you have likely seen on the site.
"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."
"everything is from the synth to the zoom recorder, twin t drums, xor snare, pt2399, and cmos stuff.
attiny85 reseting the phase of 40106 oscilators, the digital control accepts 1voct from keysetp and go to the 40106 inputs through resistors, a little rc for filtering the pwm, and for this reason when you change the oscillator frequency you can get intervals and crazy stuff. is not orthodox but suits my need for Rich timbres. the dco goes to 40106 buffers , and then 4040 dividers, twin t filters, one for each of the two voices, one goes to env, vca, filter, delay, and the other one to clock divider and filter, to get the sub osc.
firmware super simple only for checking the conversion from filtered frecuency of the attiny85 to my 40106 non exponencial vcos.
currently is tracking 10 octaves really good, the trick is put a voltage divider in the cv in of the attiny because keystep has 0 to 10v and the attiny accepts 0 to 5v tehn the tracking inside the attiny converts o.5v oct to 1 volt oct. i dont know anything about coding but i made it with chat gpt and my design .
source code will be in the coments ."

"Entanglement uses a 1D quantum wave function (Schrödinger equation) to produce evolving waveforms for use in a dual polyphonic wavetable synthesizer. You can add energy to the simulation in various different ways (wave packets/quantum particles, free draw, and waveform files) and those waveforms will evolve and transform based on the equation and your settings. You can also add environmental factors (potentials) to transform the energy/waveforms in different ways. Additionally you are able to manipulate the resulting waveform in different ways (stretching, warping, quantizing, smoothing, FM etc). You can derive your waveform from the wave function with many different equations and value options each of which offers a different sound. Each oscillator has its own independent wave function, energies, potentials and settings. Both oscillators can also be entangled adding a rich and complex modulation of the waveforms. That coupled with an internal modulation system makes this device a powerhouse for insane sound design! From basic synth sounds, to complex evolving sounds, to crazy mind blowing sounds. The evolving nature and very compelling transformations of the waveforms through the quantum wave function stands this synth apart from the many other wavetable synthesizers out there.

"Tom takes a look at Smear, the debut module from Smoothie Audio. It’s a dual stereo 98-pole allpass filter, and it’s capable of some pretty mind-bending spectral effects.
"We say... It's not often that we come across something genuinely new and innovative in Eurorack these days, but Smear is just that - a pair of stereo 98-pole all-pass filters that open up all sorts of strange sonic territory. Brilliant!
Manufacturer's description Smear is Smoothie Audio’s first Eurorack module - a dual stereo 98-pole allpass filter unlike anything else in your rack.
At its core, Smear takes a deceptively simple concept - the allpass filter, usually buried deep inside reverb algorithms — and refines it into a playable, sculptural processor. A single allpass subtly shifts the phase of incoming audio while passing the entire signal unfiltered. Stack 98 poles in series, and the effect becomes striking: frequencies across the spectrum are delayed by different amounts, creating a rich spectral delay that can smear, morph, and transform sound.
Smear can be become different effects, according to how you set the parameters:
Transient Smearing & Spectral Delay that reshapes transients, can add punch Resonator & Percussion Voice for metallic, physical-modeling tones when pushed into feedback territory Morphing filter & Phasor for animated timbral movement Interface & Controls
The panel is laid out symmetrically, with two identical sections (Left and Right). By default, stereo audio flows left → right → out, but a dedicated Split Mode allows each side to process audio independently.
Each section offers three core parameters — Frequency, Resonance, and Stages — each with dedicated CV inputs. Frequency and Resonance have attenuverters for precise modulation. A global Feedback control (with CV) unlocks resonant, flanger-like, and physical-modeling behaviors.
The Stage sliders reveal Smear’s hidden depth: with LEDs indicating crossfade modes between filter poles, you can dive into complex notch filtering, animated flams, and evolving timbral movement. Modulate them, and the module comes alive with unpredictable, dynamic filtering effects.
