FFG

FFG stands for Falsch Farben Generator, literally, fake color generator, the original name of the circuit when it was published in german magazine Funkschau in 1987, realised by M. Klose and H. Neumayr.

The project have been resurrected recently as “Visualist” by Berto A and the documentation have been translated and publish on Makezine. The original doc (in german and in italian),  Berto A documentation and gerber files for the original board are available here.

The FFG is based on the original circuit and adds some modifications, mainly video rates CV control over each parameter (R, G and B level and comparators threshold) and NTSC/PAL compatibility.

The project will be soon available as a built unitDIY kits and circuit boards.

(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.

(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.

Okay, so this is how synced modulation looks like on FFG last revision. 
Quite happy with it so far, need some more tweaking on the CV inputs, so they’re 1V compatible to match levels coming from an LZX system. Each inputs have an attenuator, so standard 5V signals can be tamed a bit. *Two LZX Castle VCO modulating low and high threshold of FFG comparators, FM on the oscillator synced to hsync.* #videoart #analogvideo #ffg #falschfarbengenerator #lzxcastle #diy #syntonie #thispersondoesnotexist

Pre-orders for CBV001 modules and standalone units are now open! 
Expected shipping date: early February for modules, end of February for standalone units.  Footage processed in NTSC, stabilized using Stable and captured with BM Analog to SDI + Video Assist.  #videoart #analogglitch #analogvideo #cbv001 #stable #eurorack #syntonie

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
