Additional Signal Sounds listings

"Tetrax follows a lineage of touch-based Ciat-Lonbarde instruments, built around four wooden bars that are pressed to activate four internal oscillators, each with its own fine-tuning slider embedded directly in the bar. Two master pitch knobs and two master chaos knobs shape the overall sound, with each chaos knob gradually increasing modulation from one oscillator to the next in a circular pattern, taking the instrument from pure sawtooth tones into dense noise.

The duplicated master controls reflect Tetrax's focus on timbre modulation via the separate upslope and downslope of triangle waveforms, giving independent shaping in each direction. Twenty-eight banana-jack modulation points are arranged in four diagonally shifted columns corresponding to the four bars, colour-coded by function — cool colours for inputs, hot colours for outputs — enabling touch-patching by pressing banana studs directly by hand. A stereo mini output reflects the press/release cycle of each bar across the two channels, and the instrument runs from either the included 12V PSU or a 9V battery."

CHOMPI is Open Source!

video upload by chase bliss and CHOMPI CLUB

"Our little pal CHOMPI is officially being discontinued.

That's the bad news.

The good news is that we've decided to make it open source as a result. You now have everything you need to edit firmware, create your own firmware from scratch, and even physically build a DIY CHOMPI of your own.

We're also releasing a new beta firmware called WAVE – a wavetable synth – that's available for everyone to play with, and an ideal starting point for open source work.

You can find everything you need to get started on the CHOMPI website.

Kaitlyn Aurelia Smith: The shape of what remains with Rev OCEAN, MiniFreak and KeyStep

video upload by Arturia

"Kaitlyn Aurelia Smith’s music draws on classical training, years of exploration with modular synthesizers and a deeply physical relationship with sound. The American composer, producer and synthesist brings these experiences into intricate electronic arrangements, orchestral passages and a voice transformed through processing.

We joined Kaitlyn along Portugal's Atlantic coastline to explore her creative process, evolving sound and the ideas behind her forthcoming album, alongside a vivid performance of GTP! shaped with Rev OCEAN, MiniFreak and KeyStep.

RUIN: IT’S NOT JUST MUSIC is out October 2 on @someonespecialstudio."

Jaap Vink and Cascading Multiplication

video upload by La Synthèse Humaine

"Jaap Vink was a technician and teacher at the Institute of Sonology in Utrecht from 1967 until his retirement in 1993. During that time he pioneered numerous techniques for the analog realization of dense electronic sounds and was a key collaborator of Roland Kayn in the 1970's and 1980's. Vink was always in search of sounds that would break the inherent periodicity of electronics, and found that feedback was the key.

This video is the second in a mini-series looking at Vink's techniques which were documented by the fantastic retrospective double LP on Recollections GRM. We look at two patches which are structured around cascades of ring modulators - creating many sidebands and dense tonal clusters out of simple sources.

Tre Modular - State of Mind (RSG first look)

video upload by Tre Modular

"Introducing State of Mind, our upcoming Eurorack Workstation. In this video we want to show you one part of what it can do. And that part is RSG, the Random State Generator. Whole 10 minutes of uncut video of RSG in action.

RSG is State of Mind's random melody generator. With the Musicality control you can choose between true random voltages, that can be quantized or played as they are, and structured melodies that play like a song, or anything in between.

At full Musicality, State of Mind takes a random stream of voltages and applies a set of musical rules to it. Essentially, it writes songs. Each time a song starts, each of the four voices draws its own character: where it sits in its range, the rhythm it leans on, a melodic shape it keeps coming back to.

Every voice has its own pitch CV and its own gate, and the gates carry the rhythm: which steps play and which rest, how long each note is held, when a note ties into the next. It pushes against the beat, leaves space and holds notes where it wants to.

Depending on the mode you set, the four voices work together in different ways. They can play chords with the lead, move beneath it in fifths and octaves, hold a chord tone, answer with a line of their own, sit on a bass note, or each go its own way entirely.

Why do we call State of Mind a Workstation? Well that's because it can do a lot more than making random melodies. Stay tuned to find out more of what SoM can do.

Enjoy!

Lo-Fi Electronica with Granular Piano & Soft Synths | Touch the moon 2026-09-30 by atnr

video upload by atnr

"An electronica piece where lo-fi piano textures overlap with quiet harmonies.

This piece was created with the OP-1 field, norns shield, volca fm2, and Omnisphere 2.

On the OP-1 field, a phrase is played using the ENDLESS sequencer and processed with reverb through the blueSky.

On the norns shield, a piano performance is recorded into graintopia and played back with granular processing. The output is connected to the Chase Bliss LOST+FOUND for delay and reverb.

The volca fm2 is processed through the Guyatone AE-5 for echo, followed by reverb through the MICROCOSM. The PHRASE LOOPER in the MICROCOSM is also used to capture and repeat phrases.

The remaining parts are built in Ableton Live using Omnisphere 2.

Whimsical Raps Atrium -CALC- Brass Bahnd in the Lobby - Atrium as desktop module with Launchkey

video upload by -CALC-

"Today's etude d'Atrium. Using it a a 5 voice analogue desktop synth controlled by a Novation Launchkey in Chord Map.

Atrium is a wonderful, complete and comprehensive instrument that sits very well on it's own terms.
But it can also be an incredible desktop module with functions, features and most importantly timbres that are totally unique.
Here it is simply using the FM synthesis mode to provide 5 voices of lovely analogue sawtooth sweetness FM only comes in later. Halfway through the looping envelopes activate to bring natural articulations to each of the 5 voices. As a (lapsed) trombone player it gives me great joy to hear how close to a trombone ensemble this comes. The chords are being fed from a Novation Launchkey Mini 37 with pads set to the superb Chord map with adventure and exploration set high. So much work went into developing and curating the chord map and its a joy to use, even for one fingered musicians.

I would say that 2026 has easily been the year of the Atrium in my world, and its only been the first year of Atrium in my world. It won't stop there either.

What an instrument Whimsical Raps have managed to bring into the world.

......It has my heart"

The Digitakt II and Outbox 8 Are Perfect Companions

video upload by EZBOT

"The Digitakt II is my favorite sampler I own, I absolutely love it. Now that I have Outbox 8 on the table, I am constantly trying to find the perfect way to utilze external effects for individual tracks. It's truly a journey. I recently found a cheap mixer that I can use to sum outputs post-fx, it feels like it's finally starting to come together. Let's dive in and chat about it, maybe make some tunes while we are at it."
