TRQ

TRQ: Composite video color inverter

The circuit is based on the “Truqueur” by Hervé Cadinot, published in “Montage électroniques pour vidéo” in 1994. It can invert the content of a composite video signal, and wipe between original and inverted video, with gain control on original and inverted signal.

It’s interesting to note that the design seems quite inspired of the “Video Colour Inverter”, published in Elektor Magazine November 1984.

TRQ V2 adds a second wipe, with a CV/audio input so the wipe can be controlled with an external signal. This signal can be processed using the internal sample and hold (based on René Schmitz YASH).
TRQ produces various glitch effects, with bright colors. A rotary switch can select between 8 effect intensity, and a potentiometer attenuate this effect.
The project is now available through the shop, either assembled, in kit or pcbs only.

(This is an extract of the last newsletter, part 3/3)
Stable update  The second revision of Stable has been built and tested, improving the noise level greatly by the use of active attenuverters, better power decoupling and moving the design on two boards instead of one, in order to help with the board layout. 
Active attenuverter also allows for a better nulling of the CV modulation when the attenuverter is centered, particularly useful since the Contrast, Brightness, Hue and Saturation CV inputs are normaled together.
Hard to give an ETA yet, as there is still some things to fix, asking to revise both boards, then the firmware is mostly done, recently added support for all HD formats supported by VU007B, meaning Stable can be used as a Luma processor (no hue or saturation control, unfortunately) and stabilizer with HD Component.
Though, hope to have it ready during the summer. Wait and see I guess?  Video showing what Stable can achieve on it’s own, without any other modules involved. Messing with the contrast, brightness, hue and saturation parameters until 0:25, then using the pre-processor jack output (unprocessed video input) into the CV inputs until 0:44, and the last part is using post-processor output as modulation, creating some nice feedback effects typical of Composite video glitch.

Combing audio and video is about as satisfying as it gets.  #analogvibes #bastlinstruments #truqueur #videoart
(This is an extract of the last newsletter, part 2/3)  Cadrans update  Now that the work on Rampes is done, time to work on the next revision of Cadrans. Been modifying the current revision for the past week or so, fine tuned a couple things, will be spending a few more days on it to exhaust what I can do with the current revision of the boards.
Once done, schematic and board files will be revised, and finger crossed, those will be the production revisions!  Video demonstrating the crossfading feature of Cadrans, one RGB feed is made with Rampes shapes into Seuils input and CV input, the other feed is a stock video decoded with Entrée and processed through Isohélie for posterization. Both are faded using Cadrans, using one of Seuils logic outputs as a CV first, giving a keying related to the shapes, and then using Y output from Entrée into LZX Keychain to generate a key based on the external video.

Here I share with you the presentation Teaser of 'Confide', the new upcoming album from eluizemusik , a musicmaker from Australia all the way up to Berlin in the Techno environment.
This track's name is "Elapse", and you'll find it in the complete LP which is going to be released by craigieknowes label on 8/04.
So glad to have received this opportunity! - The video was made completely by me, mixing usage of analog and digital circuitry, new and old, using it as it properly should be used or using exactly some of its malfunctioning.
Big thanks goes also to Bastien Lavaud holographic_thought_process , which let me build an early prototype of a Composite video distortion/ color inversion unit: The Truqueur, and you'll be finding it as a kit soon on www.syntonie.fr .
A point of View about these sounds, if you will - 
Enjoy the view/sound 😀

Pronti per l'uscita di #confideLP! eluizemusik con questo album ti porta a spasso tra meditazione, armonia e bellissimi panorami sonori. 
Allegato all' album uscirà il video ufficiale di Elapse, contenente una controparte visiva di cosa sentite; segnali mischiati, misture di apparecchi nuovi (#truqueur) e vecchi, analogici e digitali, e malfunzioni totalmente desiderate.
Stay tuned!  ENG/ 
Ready for Confide LP releasing tomorrow!
eluizemusik is gonna take you around amongst meditation, harmony and beautiful soundscapes.
Elapse 's official video is going to be attached, containing a visual counterpart of what you hear; mixed signals, a mixture of new circuits (#truqueur) and older ones, analogue and digital, and totally desired iridescent malfuctioning.
Stay tuned!  #glitch #glitchart #audioreactive #lissajous #oscilloscope #diy #newmedia #av #compositevideo #analogvideo #analogcolours

Entrée is now available!  Entrée (pronounced [ɑ̃.tʁe], french for input) is a Component to RGB colorspace converter and Luma Processor with the following features:  - Decodes SD/HD Component (YPbPr) to 1V RGBY outputs.
- Y signal is normalized to the processor input which features an attenuverter (contrast) and offset (brightness), plugging a jack in the processor input will break the normalization to allow the processing of another signal.
- Y pass-through RCA at the rear of the module to sync the sync generator/encoder to the external video signal.  It is an update of VU003B with a couple improvements:  - Low noise power supply
- Active attenuverter in the processor part
- 75R output impedance on the 1V output jacks to increase the bandwidth, resulting in a sharper picture in HD formats.  Some of those improvements can be applied to VU003B (both DIY and production versions), the details of those modifications can be found on Syntonie GitHub.
Get in touch by email if you’d like to have your VU003B modified.  The module is powered through standard Eurorack connector or DC barrel.  Inputs:  0-700mV Y, Pb, Pr, 75ohm
0-1V Processor In, 100kohm  Outputs:  0-1V R, G, B, Y, Processor Out, 75 ohm
0-700mV Sync Out (rear), 75 ohm  Specs:  - 8HP
- 90mA +12V
- 0mA -12V
- 0mA +5V
- 45mm deep  #eurorack #videosynthesis #analogvideo #syntonieentree #syntonie
