"Kassiopeia is a 4-channel DC interface that lets you control motors, solenoids, LEDs, fans, lights and more with MIDI or CV/Gate.

Tap, shake, vibrate, and move objects to create sound in ways you’ve never imagined. Build kinetic sound installations, trigger solenoids rhythmically, or illuminate objects for an immersive performance.

What if sound wasn’t just about speakers and synthesizers? What if you could make music by striking metal plates, shaking objects, or vibrating strings?

Kassiopeia is a 4-channel DC interface that turns movement into sound and light. It lets you control motors, solenoids, fans, LEDs and lamps using MIDI or CV/Gate. Each channel can either smoothly adjust power levels (great for controlling motors and movement) or send short, punchy triggers (perfect for percussive hits).

Designed for experimental musicians, sound artists, and tinkerers, Kassiopeia lets you:

Trigger solenoids to create percussive rhythms on any object.
Control motors and fans to shak, vibrate, or bow strings.
Control lamps and LEDs for an immersive performance.
Build kinetic sound sculptures that interact with the physical world.
Power-starve devices for glitchy, unpredictable results.
Simply connect it to a laptop via MIDI (Ableton-ready!) or control it with CV/Gate from your modular system.

During its development, we worked closely with Hildur Guðnadóttir and her band Osmium, incorporating ideas from the modified Halldorophone used in the Joker soundtrack. It’s an instrument of endless possibilities—where will you take it?"

KASSIOPEIA actually made its first mention on the site back on May 7, 2025.

Easel Sample Transformation

video upload by Todd Barton

"I'm always amazing how the Easel can transform & transmogrify a single sound. I begin with a single gong hit sample from the Morphagene going into Aux In on the Easel. Slowly gate that then move on the Balance Modulate it and finally bring in the Complex Oscillator for some thumps. Enjoy!

ULTRAMASTER KR-106 Open Source Roland Juno-106 Soft Synth Emulation

"A virtual analog synthesizer inspired by the classic Roland Juno polysynths, with DSP calibrated from hardware measurements, firmware analysis, and factory schematics. 6-voice polyphonic.
Free and open source. AU, VST3, CLAP, LV2, and standalone."

Additional details via Reddit:

"We started building a Juno software synth in a Brooklyn loft in 2000. 25 years later, we're releasing it as open source. Meet the Ultramaster KR-106.

Back in 2000, my buddy Dave and I started Ultramaster Group with a wild idea: professional audio software for Linux. We were young, broke, working in a loft in Brooklyn, and perhaps a little bit ahead of our time.

Life happened. I went on to start a screen printing studio. Dave ended up at Google. But we never really stopped thinking about the synth.

Fast forward 25 years. Hardware is exponentially faster, DSP methodology has evolved, and we now have access to oscilloscopes, service manuals, and communities like this one. So we went back to the source code and overhauled everything.

The KR-106 is a 6-voice polyphonic Juno-106 emulation with:

Per-voice DCO, VCF (TPT cascade, IR3109 OTA-C design with 2x oversampling), VCA, and ADSR
Sub-oscillator (CD4013 flip-flop model) and noise source (2SC945 avalanche model)
PWM modes (manual / LFO / envelope)
4-position HPF (bass boost / flat / 240 Hz / 720 Hz)
Per-voice component variance modeling analog tolerances (pitch ±3¢, envelope ±8%, VCA ±0.5 dB, pulse width)
BBD chorus emulation (MN3009 modeled with Hermite interpolation)
Arpeggiator, portamento, Mono/Poly I/Poly II key modes
Two calibration modes: '1984 Mode' (firmware + schematics) and '1982 Mode' (circuit analysis + hardware measurements from my own Juno-6)
128 factory presets decoded from original SYSEX data
AU/VST3 on Mac, VST3/LV2 on Linux, VST3 on Windows, plus Standalone
It's 100% free, GPL-licensed, and we don't take donations. We just want it to be as accurate as possible, and we'd love help getting there.

Nonlinearity And Feedback

video upload by La Synthèse Humaine

New Uses for Old Circuits

"New Uses for Old Circuits is a series looking at linear and nonlinear processes in the modular system.

In this video we look at simple feedback systems and explore linearity and nonlinearity. We see how basic audio feedback through a linear system (basically a volume knob) can accentuate or attenuate what is already present in a sound. But sending the feedback through a nonlinear system transforms the sound into something else entirely."

Shakmat Ballista Blast | What This Module Can REALLY Do

video upload by Braintree56

"Shakmat Sent me the Ballista Blast to demo for you.

In my first video on the Shakmat Ballista Blast, I gave a brief overview and some first impressions...

But once you start digging into it, you realize this module goes way deeper than that.

In this video, I take a deeper dive into the Ballista Blast and explore what it can really do when you push it beyond a simple voice. From advanced modulation routing to the different synthesis engines, this module starts to feel less like a utility voice and more like a flexible sound design tool. I'm going to show you the whole thing!

• Assignable envelope routing to multiple destinations
• Built-in randomization for evolving patches
• Multiple Engines and Modes

All of these features can be combined in ways that go far beyond a typical 'starter voice.'

If you're building a compact case—or just want to get more out of a single module—this one has a lot to offer."

S4: Track in 10 posts

"An empty project and 10 minutes on the clock. In an uninterrupted one take we explore ideas, sculpt sounds, and let the S4 sculpting sampler guide the moment. 'Track in 10' is about staying in the flow and creating without overthinking. In this video we take two vinyls, and record them into the S4, building a full idea from scratch in real time. Everything is captured: the decisions, mistakes, and happy accidents.

Redshift 6 - Trance Build Up - Sequencer Demo

video upload by Supercritical Synthesizers

"5-part sequencer demo with supersaws. All running on Redshift 6’s internal polyphonic sequencers.

All synth sounds, sequencing, and FX in this trance build-up are created with Redshift 6. When all five parts are playing, there are nearly 90 oscillators running simultaneously.

The new beta firmware — featuring the sequencer and macros — is now available on our Discord server: / discord

The new sequencer engine is per-part, meaning up to six independent polyphonic sequencers can run simultaneously, each on its own dedicated part.

All synth sounds and FX are from Redshift 6 — no external effects were used."

video upload by DivKid

Also see Turing Machine, Workshop System & Planet of the Apes! // Music Thing Modular at Machina Bristronica

"Seeing the Music Thing Workshop System grow and develop over recent years have been a lovely thing and it made me happy to see part of it getting broken out into a Eurorack module and for that part to be the Workshop Computer. It's an 8HP Eurorack module that works as digital toolbox for audio and CV which offers all sorts of handy low level utility things, more exciting audio and CV generation and a range of more lo fi and hi fi audio FX.

Along with the release of the module are 3 new program cards from RYK, offering pitch shifting delay, vocoding, pitch to voltage and tape style recording and looping. You also get some default Music Thing cards and there's blank cards with a huge range of simple drag and drop a file over USB options for a range of community cards you can get for free too. Check out the links below, loads of info in the timing index to skip around. Enjoy!"
