"Ciat Lonbarde Tetrax Semi Modular Synthesiser - it is used but in great fully working condition. As is often the case with these CL barre synths one of the keys triggers sounds from left to right rather than right to left like the rest. Power supply not included (needs 12v 1a positive tip)"

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."

Kozepz and Weinglas at Noodlefest
Published on Oct 17, 2017 Wein Glas
"After an earlier collaboration this year, their album FRNDS, Weinglas and Kozepz got the opportunity to perform a live set together for the very first time at Noodlefest 2017, V2, Rotterdam.
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."
Update on the gear used: "Kozepz and Weinglas making noises with Cocoquantus, Plumbutter, two Hordijk Blippoo boxes, some samples, and a Tetrax!"

Meng Qi - Playable Patchbay 0
Published on Oct 22, 2014 Qi Meng
"This is an instrument I made to experiment with “playable patchbay” principle.
Most modular synth controllers are made to generate expressive control signals in real time based on players’ controls. I decided to take a totally different approach of control by bringing the whole synth patching process onto playing interface.
Modular synth systems usually utilize an interface assembled with jacks, and some others utilize patching matrix such as EMS VCS3. The time and gestures involved for both interfaces are much, and in most cases it is not practical to alter multiple patch connections at the same time.
This instrument has an patching interface with springs and conductive ink, not very much unlike a matrix patchbay. But now all points can be patched by simply pressing the springs on to the board, similar to playing gestures of some string instruments, multiple signal connections can be done at the same time without effort.
CL Tetrax is chosen to take part for sound synthesis in this instrument. It’s an analog 4 voice engine based on Peter’s unique synthesis principle.

Patch Point Sidrax Organ by Ciat-Lonbarde
Note: Auction links are affiliate links for which the site may be compensated.
via this auction
"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."
