"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.
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 Tetrax 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."

Tetrax vs the Buchla

Published on Jun 20, 2013 d4nnyp·25 videos

"Ciat Lonbarde Tetrax and Buchla.

Tetrax goes into 230e and then into the mighty 296e. Tetrax controls 259e, the 259e is modulating the 296e and also being output through a 292e. and other stuff like that........"

"Patching a Ciat-Lonbarde Tetrax with a Serge Creature/Gator.

Lots of cross modulating stuff, pressure/release from the barres sends CV, some FM both to and from creature, sample and hold into Tetrax, yada yada.

Sound is from both Creature and Tetrax."

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.

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."

Extended Tetrazzi Test

Published on May 17, 2013 NakagawaGakki·43 videos

"Here are some excerpts from my first test with the Extended Tetrazzi I have built. I spent about an hour exploring it right after I first turned it on this afternoon, sooo much fun.
The Tetrazzi PCB was ordered from Super instrument designer Peter Blasser at Ciat Lonbarde - http://www.ciat-lonbarde.net/tetrazzi/ Its sadly discontinued now, but the Tetrax is now available.
I want to take this basic design and extend it to become a more expressive and per formative instrument in my setup. I took some inspiration from the way the Tetrax is laid out.
I started by making the wooden play Barres longer to create more flex, a kind of "Differential Lever". This basically means that pressing down (and pulling up!) on either side of the fulcrum will produce different results. This modification alone has added a lot more subtle expression to the Tetrazzi.
I have brought all the SQT and TRN points for each internal Oscillator out to a metal (banana) jack that doubles the function. I can use the socket as a touch point to "bend" with my fingers but also temporarily hard wire these connections to retain a patch. Also these Banana jack are standard on Modular Synthesizers so I hope to be able to interface this with my modular in the future.
There are still 3rows of jacks that are unused ATM, I hope to further modify this instrument to add even more playability. There are many ideas at http://pugix.com/synth/modular-tetrazzi/ who has completely opened up the Tetrazzi and converted it into a fully blown Modular Panel.
Although I wont go this far I hope to glean some valuable info from his site.

The case of my Extended Tetrazzi has been designed and cut by me in the CAD/CAM environment using a CNC machine. The Barres have been especially carved down (on the underside) in such a way that they flex right over the hidden piezo sensors.
All wood is reclaimed Jarrah floorboards from a house that was being demolished nearby my workshop."

"The only sound sources here are the Tetrax oscillators. They are sequenced by the Serge TKB then run through the WAD, and later through a BugBrand PT Delay.
Watch out for real Tetrax craziness around 3:25.
This little device is tons of fun, besides being ultra playable and reactive ! Plays nicely with his bananafriends too :bananaguitar:"

Ciat-Lonbarde Tetrax

Published on Nov 19, 2018 Robin Rimbaud-Scanner

"First experiments with the beautiful Ciat-Lonbarde Tetrax, using only an Eventide H9 pedal for effects and playing it live, no editing. Such a beautiful instrument, intuitive, unusual and rich sounding and this is without even patching it within itself to produce even wilder results."

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."

Todd Barton - 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.

Dreamwalking - CL Tetrax Solo 1

Published on Mar 27, 2013 7numan7·73 videos

"This is my first recording of the amazing Ciat Lonbarde Tetrax instrument (or any CL instrument for that matter - I'm usually having too much fun when I play them to record anything). You play it by pressing wooden barres. And it can be played with a variety of performance gestures (such as the violin-like "cad. It is easier to tune than the older version (Tetrazzi) and can be patched with banana cables, as I demonstrate here.

Enjoy!"
