Happy 2026, as always, thanks for the support during the past year! Jan 6 Haven`t had much time to see actual human people lately so I`ve used some of my few spare moments to build some new friends. Oct 19 In combination with Entrée and Sortie, Seuils makes for a nice coloriser by processing R, G and B channels from an external video source. Dec 17 CBV001 is now available in standalone version, comes with a 3D printed enclosure, power supply adapter board and external wall wart. Jul 27 Seuils is back in stock! Dec 15 Rare picture of myself in my natural habitat, staring (and probably cussing) at an oscilloscope. Nov 26 Animate EXP and Solaire are back in stock! Nov 3 Stable is back in stock! Oct 21 Posterizer lovers and limited color depth enjoyers, Isohélie is back in stock! Oct 1
2025 has been a bit slow in terms of releases for Syntonie, mostly as the focus was made on production and re-stocking the existing line up of modules, so the good news is that (almost) everything is in stock currently!
Two modules were released last year:
Détail, a Composite video filter that builds upon Syntonie analog glitch legacy, bringing some classic analog video effects in modular format, with voltage controllable parameters so it integrates perfectly in the 1V ecosystem.
And Sortie, the new incarnation of our RGB encoder/sync generator, the heart and brain of any video synthesis system.
Wish all of you the best for the year to come, keep videoing!
ps: Animate + its expander are currently available as a bundle with 15% off on Syntonie webshop.

But, seriously, apologies to my human friends for being so MIA the last couple/few months. I miss y`all and hope the nonstop work madness stops soon.

Entrée converts the external Component video signal to RGB, so it can be processed by Seuils, and Sortie encodes the resulting RGB back to Component.
Patching feedback from Seuils outputs back into its CV input generates glitchy effects like ringing and/or clipping.
Recorded in Component 720p60.

Note that enclosures are printed on order, usually takes 1-2 weeks when CBV001 are in stock (just finished building a new batch).
Got a few built CBV002 in stock too. Will build more VU005/VU006 soon, in the meantime, there is probably some available from retailers (@rawvoltage_vienna in the EU and @midwestmodular in the US)
Waiting for the last revisions of the 4 new VU, hope to have them available for Fall.
CBV003/TRQ eurorack version will take a bit more time, as first revision doesn’t work properly.
FFG build/kits have been discontinued (PCB sets are still available until stock lasts). No ETA yet on the eurorack update, as it will mostly depends on my progress on the sync/blanking generator, as the update will focus on making it useable as a sync generator/RGB encoder (without relying on an external video signal), adding more CV capabilities, as well as keeping the original 8-bit posterizer/colorizer processing.
About the sync/blanking generator, received and tested the last revision of the video genlock PMOD board for iceBreaker FPGA dev board, so I can resume writing the code. Then aiming at making a board that will include the FPGA, so I can use it across multiple projects, as it will have plenty of uses (composite/component video processing, glitch stabilisation, “standalone” synth)

Here, it is used to modulate Stable parameters, with Stable pre-proc output going to Seuils inputs, making this keyed/clipped-like effect. Stable post-proc output is going into Seuils CV to add some feedback, with Seuils attenuverters controlling the amount of feedback.
Recorded in Composite NTSC/480i59.94.

Went into a major overhaul of my workspace at the beginning of the year, partitioning it into better defined areas, as well as adding more storage space. Pictured here are the prototyping bench (left) and the assembly bench (right).

Here is one of my go-to patch: ramps and shapes from Rampes into Cadrans, with amplitude modulation from Animate + Animate EXP to add some motion. Outputs of Cadrans into Solaire, outputs of Solaire into ReverseLandfill Matrix Mixer, encoded in Component 720p60 with Sortie.
(Note that this is the last batch of Animate EXP and it won’t be re-stocked, so probably time to grab one to add some waveforms to your Animate)

I was asked if Cadrans would make a good addition to Stable. While it is probably not as instantly gratifying as other processors like Solaire, Seuils or Isohélie, Cadrans and its amplitude modulation is a good way to modulate how much feedback is applied to Stable.
To do so, Stable post-proc output is connected to Cadrans input, output of Cadrans going back to Stable CV inputs, closing the feedback loop. Then, a pitch sequence from a step sequencer (here a Beatstep Pro) is used as CV for Cadrans, essentially automating the feedback in sync with the music.

Next on the re-stock list are Solaire, Animate EXP and VU001C.

Here used to process a picture, with Entrée, Rampes, VH.S Baja, ReverseLandfill Matrix Mixer and Sortie.
Animate EXP, Stable and VU001C restock will follow shortly.
Until next time!
