"Text by Peter Blasser

The Sidrax Organ follows a lineage of electronic musical instruments based on touch. It was redesigned twice, first as Sidrassi, then as Sidrazzi. It has seven wooden bars that you press to express seven oscillators within. Each oscillator has its own fine tuning slider, embedded right within its bar. Also, there is a master pitch knob, and a master chaos knob. The master chaos knob makes the instrument go from pure triangle tones to a nest of noise. It does this by gradually increasing modulation from one oscillator to the next in a circular pattern. Sidrax has enough bars to construct sweetest melodies from the triangle waves, whereas Tetrax is a simple four-bar entity, with complexity of tone for funky bass.

There are 44 modulation points brought forth as banana jacks. They are arranged in seven columns, representing the seven bars. Their layout is shifted diagonally, to allow inputs in proximity to outputs. This is for touch-playability; you can make banana jack metal studs that can be squished by hand to gesture-patch the instrument. Inputs are cool colors: blue, green, and grey. Outputs are hot colors: red and orange. The grey jacks are parallel inputs with the master knobs: the one on the left is for master pitch, the right one is master chaos. The color allotment for each bar is as follows:

Two orange jacks, representing the press and release gestures on that bar in voltage.
One red jack, which is the pure triangle output of that oscillator.
Two green jacks, that are "glitch" inputs. They cause the boundary conditions of each oscillator to wire to the output of another. A modulation inspired by circuit bending.
One blue jack, an fm modulation input for that oscillator.
The Sidrax organ has a stereo-mini output on the back. This is because each bar, outputs in different channels during the press/release cycle. In addition to the stereo-mini jack, it has an power switch, and optional built-in batteries, or an external, 9volt battery snap."

Cxaxukluth Drone Synth - Demo //01 (drone, ambient, NTS-1, MSG II)

Lowering Skies

"Just to add a bit more of context here. I'm making a Drone synth for iOS and this is its demo. It's a pretty simplistic soundscapes exploration tool primarily targeted to live sets and recordings. Cxaxukluth consists of two Morphing wavetable oscillators, one sub-oscillator and one additive oscillator to smooth rough edges when you need it. There's also a bit reduction algorithm, a cascade of effects, two LFOs and a number of organic unparalleled logic to mix it all together. That's the main part I'm currently testing and working on.

The video also features Moffenzeef MSG II Synthesizer which I love and my new Korg NTS-1.

It's currently in Round 1 Alpha testing and you can try Cxaxukluth right now via TestFlight.

Follow the link https://testflight.apple.com/join/WfG... from an iPad and have TestFlight installed. I would love to hear what do you think about it!"

Koma Electronic Field Kit for the mixing.

Cxaxukluth (Drone Synth) // tech demo 02 (Tetrax, Field/FX Kit, Moffenzeef MSG II)


"Another tech demo of the upcoming iPad drone synth Cxaxukluth. This time with Ciat-Lonbarde Tetrax and Koma's FX/Field Kits. Exploring sub-octave and more clicky side of Cxaxukluth this time. Two main oscillators are detuned and are using different waveshapes and it creates a rhythm pattern as a result."

一念而就 / one take, not an end

"A moment seized without decoration, and a story to extend the moment.

Rotary Tetrax is based on Ciat-Lonbarde Tetrax. 360º potentiometers enable new gestures, patch bay layout accepts banana shorting bars. With built-in reverb.

Tetrax has Harmonic Locking behavior with audio at “FM Input”, which works great with unlimited single direction rotations. I’ve embedded a Teensy 3.6 for 2 channels of audio to voice 1/3, tuned 660Hz / 880Hz for this track, with symmetry control over variable shape triangle waveform.

Todd Barton - Start From Silence

https://nathanmoody.bandcamp.com/album/start-from-silence

"I'm so excited that this album is now out! Last month I met Nathan Moody in person for the first time. He dropped by my place on his way to do a talk and performance at Velocity in Seattle. After just a few hours together my friend, Bruce Bayard came by and we three decided to jam. Nathan had a cool field recorder that he setup and recorded us all in the room. The jam turned out to be sonic serendipity, a rare conjunction of modular planets. I hope you enjoy it . . .

"Recorded live in Ashland, Oregon, “Start from Silence” captures three masters of West Coast analogue synthesis performing with a focus on reciprocal listening and improvised expression.

Todd Barton, Bruce Bayard, and Nathan Moody combine a unique set of unusual instruments into a journey in tone, gesture, and sound. The aural dynamics were made in response only to the sounds, breaths, and movements of each performer. The music ranges from ambient to intense, gliding from amorphous to structured with bubbling streams of energy and contemplative drones that guide the listener throughout. The recording purposefully contains the artists’ breaths and movements, lending verisimilitude, presence, and authenticity to this organic performance.

The artists hadn’t played together before this recording, making the emergent soundscapes and sonic exploration all the more stunning…yet perhaps unsurprising, given the their combined 70+ years of composition and performing experience.

A marriage of melody & chaos with the Meng Qi Wing Pinger // Superbooth 2019

Published on May 9, 2019 DivKidVideo

"The new Wing Pinger from Meng Qi had really caught my attention with seemingly random pentatonic melodies shifting through a great spring reverb (not part of the module) on the Meng Qi Instagram page. We check out the Wing Pinger as well as some custom and one builds of Lorre Double Knot controllers and Ciat Lonbarde Sidrax and Tetrax based synthesisers."

"The Tetrax Organ follows a lineage of electronic musical instruments based on touch. It was redesigned once, as. It has four wooden bars that you press to express four oscillators within. Each oscillator has its own fine tuning slider, embedded right within its bar. Also, there is are two master pitch knobs, and two master chaos knobs. Each master chaos knob makes the instrument go from pure sawtooth tones to a nest of noise. It does this by gradually increasing modulation from one oscillator to the next in a circular pattern. The reason there are two of each knobs: the Tetrax is all about timbre modulation, by changing the upslope and downslope of triangle waves separately. So, for master pitch and chaos, there is a separate upwards and downwards knob. In general, Tetrax is for funky bass and complex tones, while is for sweet melodies. Of course they all have noise available at any point!

There are 28 modulation points brought forth as banana jacks. They are arranged in four columns, representing the four bars. Their layout is shifted diagonally, to allow inputs in proximity to outputs. This is for touch-playability; you can make banana jack metal studs that can be squished by hand to gesture-patch the instrument. Inputs are cool colors: blue, green, and grey. Outputs are hot colors: red and orange. The grey jacks are parallel inputs with the master knobs: the two on the left are for master pitch, the right two are master chaos. The color allotment for each bar is as follows:
Two orange jacks, representing the press and release gestures on that bar in voltage.

Tetrax Meets the Field Kit

Published on Jan 13, 2018 Encyclotronic

"Having some fun with the Ciat Lonbarde Tetrax and the Koma Electrik Field Kit. These things work great together. The extra LFO and mixer is handy for controlling the Tetrax, and vice versa. Note: The box uses the Solenoid switch to push the marbles against the metal objects and fed back to mix via the piezo pickup."

Part 04 - phases and tines (stay tuned for more!)

In these times of often unwanted changes it is good to have something steady: Like friends all over the world. So what can be better than two friends from the Netherlands and Germany collaborating to make international noises for one world. Noisemakers kozepz and weinglas are making the world a better place! Even if this means that we all have to listen to their dark soundscapes and aural pollutions first."
