Trivium: VCF/VCA/Envelope combo from Weston Precision Audio & Trovarsi

video upload by CatSynth TV

"LA-based electronic music composer/artist Trovarsi takes us on a tour of Trivium, a new module developed in collaboration with Weston Precision Audio, at Buchla & Friends 2026. Trivium combines a multi-state filter, VCAs, and two envelopes in one compact unit. The idea is combine these functions into a smaller space, thus freeing up space in a live modular setup for other modules unique to the artists' creative needs.

Audio Synthesis on RP2350

video upload by Ghost In Translation

"All the sounds in this video are generated from my 2 modules that I designed around Pico 2 (RP2350) : Drone and DS1, they are visible on the front row.

On these I use the port of Teensy's audio Library for Pico:
https://github.com/ghostintranslation...

Drone is the main voice here, a Drone with 4 voices with a few algorithms to choose from. DS1 is a drums module that can do many drums but only one at a time.

The RP2350 is capable of audio synthesis while reading inputs, and controlling outputs such as LEDs and more. It is much less powerful than the Teensy 4 and cannot run very complex sketches but here it shows how capable it is.

All of my designs are open source, these modules are based on the v2 of my Motherboard, I still need to update the repos but you can find everything here:

Schlappy #202day jam

video upload by SCHLAPPI ENGINEERING

"It's #202day ! The MC-202 is one of my all time favorite synth so I wanted to build a patch around it using the Schlappy Patching system.
Only the bottom row is used (apart of a Mixswitch to mix the voices).
MC-202 to Angle Grinder for additional filtering.
MC-202 gate out to two Nibblers for drum sequencing and stepped modulation.
Kick drum by two channels of the Boundary Layer.
HiHats by a feedbacking BTFLD in a Boundary.

Have fun!!

System Lizard - Iguanamente

video upload by John Schussler

"I'm a sucker for anything with lots of cross modulation. The Iguanamente has that in spades, plus it's got a unique delay built into the audio path that makes for even more craziness.

They say: 'Iguanamente is a chaotic oscillator designed to provide a Eurorack modular synthesizer with a unique and creative sound source that is suitable for percussion, noise, leads, basses, drones, and everything in between.'

Sounds about right.

This is pretty much all just the module. There is some reverb there for space, but that's it.

00:00 Intro
00:20 Main out
06:00 Main + Aux
19:43 Sequence"

This is the first post to feature the Iguanamente!

via Perfect Circuit

The Iguanamente from System Lizard is a chaotic dual oscillator built around a cross modulating oscillator and delay network. Thanks to a keen and comprehensive array of timbre and modulation controls, Iguanamente readily stretches across musical terrain, wagging its reptilian tail between percussion, texture, and melodic applications alike. At the top of the panel, Coarse frequency control sets the fundamental frequency of the system, with dedicated 1V/octave and FM inputs for adjusting frequency via CV. The Radius control manipulates the spread of auxiliary oscillators, allowing for a wide range of inharmonic and harmonic timbral expansion. Shape controls the waveshape of all oscillators, hard clipping into a square wave to the left of center and wavefolding to the right.

These oscillators are then processed through a delay network, with controls for Feedback, delay time or Frequency, and a Mix control. At the bottom of the module, cross modulation controls and CV inputs for oscillator frequency modulation, oscillator amplitude modulation, and delay time allow you to introduce nonlinear modulations into Iguanamente, sparking unique and chaotic changes in timbre. At the top right corner of the module, independent outputs for the Main and Auxiliary oscillators offer independent post processing potential or serve as a pseudo-stereo output. If you're looking for a flexible oscillator with unique character and a taste for chaos, Iguanamente from System Lizard is a righteously fun reptile for any rack.

Fieldtone Weaver Eurorack // The Happy Accidents Module // Full walkthrough and patches

video upload by Lesjamusic

Pedal version previously featured here.

"The Fieldtone Weaver is a two-second sampler with a single knob, no undo, and no going back. Now it's in eurorack.

Weaver captures two seconds of audio - via the built-in microphone or audio input - and instantly randomises it into evolving loops, rhythms, and textures. Every turn of the knob generates a completely new variation. Nothing saves, nothing recalls. It's the ultimate happy accidents machine.
The modular version adds individual level control for three loop elements, trigger outputs that double as a random rhythm generator, a pitch switch, clock sync, and CV control - which works differently to what you might expect. I go into detail on all of this.

The Gas Club, Episode 1 - Hugh Jones, Fieldtone Instruments.

video upload by Soundgas

"Welcome to our new series, The Gas Club. Where we meet people who make things - be that music, recording devices, or instruments.

In the first episode Tony meets Hugh Jones of Fieldtone Instruments at the Soundgas HQ to explore the history of Fieldtone's celebration creations. They take a deep dive into Hugh's journey from musician/engineer to designer/builder of the Box of Uncertainty, The Weaver one knob handheld sampler and brand new Weaver Module plus a sneak peak at what to expect next from Fieldtone in 2026.

Tony and Hugh discuss the joy of sonic adventure and gear designed to produce happy accidents and the experiences of bringing new creations to the world."

A few pics and details on Weaver Eurorack:


Weaver Modular from Fieldtone is a Eurorack format version of the highly in demand Weaver handheld sampler that featured in music tech tastemaker Andrew Huang’s year round up as his Favourite Desktop FX module of 2024. The modular edition builds on the functionality of the original by adding a variety of additional control.

The Weaver is no ordinary audio sampler, it is a meditation on impermanence and chance. With a single, enigmatic knob, it embraces randomness as an artistic principle, reconfiguring two-second sound bites into hypnotic loops and evolving textures. There is no undo button, no way back once a sound is captured; the Weaver insists that you move forward, shaping the unpredictable into rhythm or texture with nothing more than a twist of the wrist or control voltage change.

New functionality on the device includes separate level controls of different elements of the loop, as well as 3 x trigger outputs which turns the device into a random rhythm generator for which you don't even need to be using the sampling capabilities. You can trigger the Recording start via CV, allowing you to keep replacing the sample whilst the loop continuously plays - something that works beautifully with acoustic sound sources such as guitar or voice, as well as electronics. A switch has also been added to select between Random or Root note sympathetic pitch playback.

Features:

Single-knob audio sampler focussed on randomness and exploration

Capture sound via built-in microphone or input jack

Fixed two-second sample time

No undo function, every knob movement generates a new loop

External sync via Clock input

Stereo output on separate L&R sockets with rich spatial movement

Separate level controls for 3 different elements of the loop

3 x gate outputs for triggering other sources

Toggle to switch between Texture and Rhythm modes

Toggle to switch between Root or Random pitch

Gate/trigger input to control Recording start

Gate/trigger input to control Weaver knob

Can be used as random rhythm generator without needing to use the sampler

Available Colours:

Forest Green (orange LED)

The "Easel" Spirit in 3U - A West Coast Eurorack Deep Dive

video upload by Sean Graves

The following is in via Sean Graves, who had the following to say:

"The piece, 'The 'Easel' Spirit in 3U: Rebuilding a Buchla Soul in Eurorack,' documents my five-year journey to replicate the specific workflow and 'soul' of the Buchla Music Easel using a curated Eurorack system."

"This post explores the creative power of 5-step sequencing (the 'migrating downbeat'), the 'origami' of wavefolding via the Verbos Complex Oscillator, and the organic harmonic dampening of vactrol-based Low Pass Gates. It’s a technical yet accessible look at why the West Coast workflow remains the 'holy grail' for performance - based synthesis."

The full write-up follows, with a demonstration of the system in the video above.

The “Easel” Spirit in 3U: Rebuilding a Buchla Soul in Eurorack

The Buchla Music Easel is legendary. It isn’t just a synthesizer. It’s a self-contained performance ecosystem. For many of us, the “Easel” workflow is the holy grail of synthesis. However, instead of chasing original hardware, I’ve spent the past five years rebuilding its specific soul within the Eurorack format. Because everyone deserves a hobby, right?

The Chef vs. The Sculptor
Most East Coast synthesizers work like a sculptor. You start with a massive block of harmonic noise (Sawtooth or Square waves) and carve it away with a filter. The Buchla workflow is different. It’s like being a chef in your own Hell’s Kitchen. You start with basic, “bland” ingredients (sine waves) and spice them up with Frequency Modulation (FM), Amplitude Modulation (AM), your choice, and then fold until the sound sizzles.

My current rig recreates this spirit by focusing on three pillars: Uncertainty, Complex Oscillation, and the iconic Sequential Voltage Source.

Part One: The Modulators (The Brain)
In a true Easel style setup, the Tokyo Tape Music Center 5-Step Sequencer acts as the brain. While most modern sequencers favor 4-8-16-32 steps, the 5-step limitation is actually a creative superpower.

Pamela's Disco: sync DJ decks to modular - Buchla & Friends

video upload by CatSynth TV

"Zoey of ALM Busy Circuits gives us a demo of their new Pamela's Disco module at Buchla & Friends 2026. Pamela's Disco connects to a PRO DJ-LINK network and converts the incoming "master tempo" to standard Eurorack clock signals that can be used to synchronize sequencers, LFOs, and modules, including the Pamela's PRO Workout (as shown in this demo). This allows modular systems to be synchronized with DJ decks and follow tempo changes and even scratches and spin ups/downs.

We also get a sneak preview of a few other upcoming modules from ALM Busy Ciruits.
