PlantsSystem-KOSMOS3 InteractiveReverb

video upload by plantssystem

"KOSMOS3 is an interactive reverb instrument that transforms reverberation from a static audio effect into a playable, responsive acoustic space. Instead of applying a fixed ambience, KOSMOS3 continuously reshapes its internal reverb field based on incoming audio, gestural control, and real‑time modulation signals.

At its core is a multi‑parameter reverb engine capable of smooth, expressive morphing across decay, diffusion, pre‑delay, and spectral balance. These parameters respond immediately to performance input, allowing the reverb to behave like a dynamic environment rather than a background effect.

Key features include:

Interactive control via MIDI, OSC, TouchOSC, and HID
Real‑time modulation for shaping spatial texture during performance
Headless operation suitable for installations and long‑running setups
Instrument‑like behavior where the reverb becomes an active part of the performance

KOSMOS3 functions not merely as an effect processor but as a playable acoustic space—a reverb you can push, bend, and sculpt in real time."

Synthesizer Pioneer Patrick Gleeson Has Passed Away

Some sad news in via The Alan R Pearlman Foundation and The Bob Moog Foundation

Celebrating the Life of Composer and Synthesizer Pioneer Patrick Gleeson

We received the sad news about about the passing of Patrick Gleeson. With respect to Pat's widow, and in conjunction with the Bob Moog Foundation, we are sharing their Press Release:

Legendary Master Synthesist Patrick Gleeson Dies at 91

On behalf of the estate of Patrick Gleeson, the Bob Moog Foundation shares the passing of the legendary electronic music pioneer. Patrick Gleeson passed away on July 19, 2026; he was 91 years old. Gleeson may be best remembered as the owner of Different Fur Studios, and for his subsequent work with Herbie Hancock. However, his career stretched well beyond those accomplishments, including producing and engineering for a multitude of musicians, recording solo albums, scoring soundtracks, and performing live.

Wendy Carlos once wrote of Patrick, "Our eight-year wait for someone else to explore electroinc music realisation with what we judge to be appropriate technical standards and musical taste has ended. In short, one hears the ears of a gifted musician at work, in a field where one must exercise unprecedented discipline and self-control."

You can read much more about Patrick's significant contributions to the world of synthesis and music HERE."

"triple reverse sigmoid chaos in 8HP."

via nonlinearcircuits

This 8HP module contains three reverse sigmoid chaos circuits, these are the same as those used in 1U reverse Sigmoid and How’s the Serenity.

This version exists because not everybody has 1U and How’s the Serenity is quite large and more focused on very slow CV generation. This version is limited to 0805 capacitors to set the timing. Tayda sell 22uF caps and you could stack these to get to 44uF easily enough. Generally, a lot of fun can be had using 1uF, 470n and 220n caps.

The syncing between the stages works very nicely with this module as the frequency ranges are closer together than How’s the Serenity, so they have a more obvious effect upon each other.

Please note if you install caps less than 470n, the 62k on that section needs to be changed to 68k. This prevents the circuit locking into a periodic orbit after CV is applied.

The caps for each section must be the same. So you will see three pads marked C1, install the same value cap in all three.

The LEDs should be very bright to shine thru the panel, a low value for RL helps too, say 2k2 or 3k3 which you are installing elsewhere on the PCB anyway. The panel renders below do not show the LEDs but they are there.

SILT - A Generative Tape-Loop Instrument by Tunary Instruments

SILT is a new instrument from Tunary Instruments who brought us ARGISH.

It's available online and as an AU/VST3/Standalone (Mac) + VST3/Standalone (Windows).

Details from the creator follow:

"I've just put out the second Tunary instrument, and it's the opposite animal: SILT, a generative tape-loop instrument.

Four short melodic loops of different lengths run through a warm tape machine and slowly drift out of phase, so the music writes itself from the drift — soft music-box tones, smeared by wow, dust and age, over field recordings of birds, stream and vinyl. Press play and it settles into gentle, ever-shifting ambient that never quite repeats. It's the Reich/Basinski tape-loop idea, turned into an instrument you just leave running.

Like everything we make, the sound engine is algorithmic — real synthesis and DSP, no AI, no trained models, no 'generate' button. You steer the mood; it does the drifting."

inMusic Donates Synthesizer Prototypes and Documentation to the Bob Moog Foundation

via The Bob Moog Foundation

Extensive Collection of Schematics, Prototypes, and More Donated to the Bob Moog Foundation Archives

The Bob Moog Foundation is excited to announce an extraordinary donation from inMusic Brands, the parent company of Moog Music. This collection of an astounding 4,489 items includes Bob Moog’s office effects from his final years at Moog Music, over 500 schematics and 700 letters spanning the 1970s through the early 2000s, and vintage synthesizers and prototype models, including a Fairlight CMI synthesizer and Minimoog Voyager bench-model prototype!

Vintage product catalogs from dozens of industry competitors and collaborators, drafted speeches and articles, letters of both a business and personal nature, and plenty of other surprises fill drawer after drawer of Bob's file cabinets. In one file folder, there might be something as everyday as a tax form or an employee review, and in the next, a poignant, handwritten letter from Wendy Carlos or Lydia Kavina! It took almost two years and many volunteers to assist the Bob Moog Foundation in accessioning these historical materials into the Bob Moog Foundation Archives.

Moogerfooger prototypes, a Multiple Resonant Filter (MuRF) test fixture, and a rare Moog Phone Controller model PC-30 are just a few more of the fascinating artifacts included, which altogether shine a fascinating light on some of Moog Music's legacy of engineering and innovation. There are far too many items in this collection to fully share here, but we created a blog post with a few more details and images. And of course, we hope to have a few of these rarities on display in the Moogseum!

Contributions like this, along with the ongoing support of our Members and other Donation sources, empower us to maintain our continually growing collection of over 15,000 historical pieces. Please consider making a donation today so that we can give this world-class archive the attention it deserves.

ECHOA STEREO DUAL DELAY AND REVERB PROCESSOR

Four delay lines total — two per stereo channel. Morph delay into reverb from first principles, from clean digital delay to smeared, textured reflections. Route the four lines in series, parallel, isolation, or spectrally. Presets, parameter lock on every pot, character engines, and more.

TIME
Delay time from 1 ms to 16 seconds, up to four taps per delay line, configurable for your sound design. Feedback up to and past unity, and a dry/wet mix per channel. Freeze delay buffers, set tempo with tap on the line buttons, or patch a clock and lock each line to a musical division. Linear or logarithmic time taper options: a full featured, clean delay line.

SPACE
Bend echoes into reverb. Diffusion sweeps a four-stage Schroeder all-pass network from discrete repeats to a wash. Bloom grows short, fixed loops into long modulated plate and hall tails. Damping is bipolar from noon — counter-clockwise darkens the tail, clockwise thins and brightens it.

ENGINE
Degrade each line's voice across with four engines — digital, BBD, tape, vinyl. Saturation, bandwidth limiting, compander, wow and flutter, hiss, crackle, digital glitches. Depth scales from bit-pristine bypass, to a gentle touch of character, to destruction.

CONFIGURABLE FOR PERFORMANCE ROUTING
Parallel, series, mono, or spectral delay-line topologies.

CV MAPPING
Per-CV destination, with attenuverters on every input.

XpandrLink, a native Mac/Windows editor and DAW plugin for Xpander/Matrix-12 (beta)

This one came in on the xpantastic Oberheim Matrix-12 and Xpander list. Details from the creator follow:

"I'm Jake, a Matrix-12 & Xpander owner and synth repair tech. For the past few months I've been building something that has gotten a lot of use in my studio: XpandrLink, a from-scratch C++/JUCE editor for these synths built using XplorerEditor's protocol and design as reference, with standalone, AU, and VST3 builds for both macOS and Windows. I've been really enjoying having this tool for my own purposes and wanted to share it with the community if anyone else might also find it useful.

First, the part that matters most to me. Like many of you, I've used XplorerEditor for years. It's a big reason these synths are still practical to own and play, and this project only exists because of the groundwork it laid. I started down this road after reading a note more than a year ago in the XplorerEditor README: the developer had no time to add new features but welcomed forks and PRs, and recommended a long-term JUCE port for a more modern cross-platform foundation.

MORPH-6: Algorithmic Lifeforms Synthesizer (First Explorations)

video upload by Laboratory 0

"Six observed entities share the same communication protocol, yet exhibit entirely different behaviors. The same signal manifests as a different physical reality within each: some proliferate like concrete, forming vast resonant structures; others retain an untamed, primordial roar; others persist as translucent organisms of granules, metal, rubber, and glass, sustained through endless cycles of fracture and reassembly.

The windows are not control panels, but communication terminals. What you see are not parameters, but cross-sections left behind as another consciousness passes through the medium. No label can faithfully translate them. Each algorithm is another point of contact with a different lifeform.

Or perhaps they have simply chosen to borrow our world as a place to be heard.

nonlinear circuits spectrum shaper

video upload by cirtcele

"I'm still learning how to use this thing but here are some excerpts from a patch with Tinkle and FM OP via Product wavefolder both fed into the Spectrum Shaper."

via nonlinear circuits

"36 channel voltage controlled comb filter aka string filter.

This module has some history. In 2018, I was part of a team putting on a show with CellF at the Todays Art festival in Den Haag. I popped down to Rotterdam to visit Dennis (aka Mono-Poly) and his studio of vintage lab gear. Dennis had an incredible patch going centred around a Bruel & Kjaer 36 channel Spectrum Shaper. Listen to his album Testlab to hear how it sounds. I just knew I had to make something like it one day. This type of filter is often called a ‘String filter’, used to emulate stringed instruments tho don’t feel limited by that.

Fast forward to 2026, I read an AES paper by R. Burhans describing his 36 channel comb filter. It reminded me there were some designs in Electronotes, so I looked them up and discovered they were both inspired by and heavily influenced by Burhans, particularly in terms of the comb filter frequencies and spacing. One was a 40 channel version by Ian Fritz using transistor based filters. He had an interesting mod, originally suggested by Lester Ludwig, where each set of 6 filters had a feedback pot. Some screenshots from these articles are at the end of this build guide. The relevant Electronotes issues 107, 115 and 116 can be found online.

The Bernie Hutchins design used 39 regular op amp based filters, along with Ian’s feedback per 6 filters mod and added an inverter so the feedback could be positive or negative (so, centre off). Negative feedback ‘flattens’ the peaks somewhat and smears the sound, positive feedback makes the peaks narrower and higher (if tuned for it, you can make them self-oscillate, see notes). Bernie also added a noise gate on the output, summing 39 channels is always going to be noisy.
