Video Synth Thread

I am very interested in the tachyons stuff do you have any video of just those alone. I checked out the website and it was hard to distinguish which boxes did what.

Just finished teaching a class where students had an assignment exploring the Vidot and then tried to recreate features in GLSL. I was kinda shocked by how difficult it was to get started with it. But I made a tutorial for the students and they were all able to get up and running with it in a couple of hours, even though none of them had used any type of modular / semi-modular gear before. They enjoyed it. I enjoy it now that I’ve figured it out.

Looks like the new synth from LZW will be more beginner-friendly… with actual text labelling of the UI.


Introduced my students to feedback and the vidiot last semester. I think they enjoyed it, even though they were making mostly colored lines. It is an interesting, confusing, confounding, and fun instrument. Usually not at the same time.

Ordered the new one to pair with it. Hopefully that will help!


What resources did you give them to learn from? I didn’t find much in the way of useful tutorials. I wrote one, but it’s filled with things like “Turn the Horizontal Sync knob (#27 on page 5 in manual)”. I encouraged students to work in pairs just so they could deal navigating the UI.


I showed them somethings, told them about the 3 patches video and turned them loose.

I also let them/ asked them to just record their outputs and incorporate those into another video project.

Maybe a little off-topic, but the first thing I thought of when I saw this was to process its output through a video synth or record video synth output onto cassette in this way (and monitor the output if using a 3-head cassette deck, albeit with a delay). The other thing that occurred to me is whether pitch/speed control on a deck might allow for a little additional quality or creativity in playback and recording, particularly if modulated via CV.

I’m also left wondering whether one might be able to use a microcontroller to handle the encoding and decoding (possibly an interesting CircuitPython project).


Stumbled over the Critter & Guitari Eyesy today:

This looks so fun and easy to use. It’s basically an Organelle for audio visualisation, with Python hackable sharable patches (called “modes”), an online patch library, MIDI control, etc.

It’s currently on Kickstarter with plans to ship this summer. I’ve always been eyeing the predecessor, the ETC and I’m definitely gonna get an Eyesy once it’s available in Europe. It seems pretty much perfect for my live-show visual needs.


So dope. I had etc installed on my organelle but I had to sell it when covid popped off :frowning:

Cross-posting from the COVID-19 streaming thread, because this may be of interest. Planning a short series on video synthesis.

Streaming from Resonant Space–tonight (Friday) at 8:00 pm EDT (00:00 GMT).

April 10 - Intro to Modular Video Synthesis - Part 1

Beginners guide to modular video synthesis–we’ll cover basic concepts of video synthesis, particularly in relation to audio modules, discuss LZX analog and digital video modules, Vidiot, Erogenous Tones Structure, glitch, and vintage video gear.


planning on having the VODs somewhere? I’ll be working (virtually) but would love to check this out.


It should be on Twitch for a couple weeks after the stream—at the same address.


I am looking for suggestions on how to mount a flat panel monitor to the wall vertically. If anyone has done that please let me know what you did.

:rocket: :cat2:

Lots of mounts can be rotated now. Or you can use an adjustable mount and just put it on sideways. That is what recently did using these:

Thanks that looks great!
I am mostly doing vertical format video lately and I wanted to set up a monitor (tv)so that I could get a better sense of how they would look.

Current at home set up.
Need a some organization tips!


It might be better to use your small monitor for feedback looping. Then you could move the camera + monitor to a tucked away spot. Everything else would fit nicely on a small table- unless you prefer the floor. For gear that uses the same input voltage and tip polarity, you can use a splitter as long as the transformer can deliver enough current.

Thanks. I hadn’t known that about the power splitters.
The small monitor is the black magic video assist for capturing the final output.
Getting the video signal to that is the big tangle point: analog to sdi to updowncross for converting to HD finally into the capture device.

When I get this back to my video lab at school it’ll be better, but still a mess! At least I have a crt there.

I enjoyed the recording of your twitch stream the other night. Keep them coming!

If you’re interested in seeing Tachyons+ Vortex Decoder, it’s featured in most of these videos here:

To other Tachyons users, which one would you recommend as a pair for VD? I’ve been thinking of adding another module to get some extra flavour, but I’m looking for a module that wouldn’t overlap too much with the Vortex one.


Ahh, the video assist–didn’t recognize that–have heard they’re super nice, though. I have a similar bunch of converters so I can input or output in multiple formats–was thinking of mounting them all to a board and making some custom cables to keep things neat. I spend hours arranging my studio, but there are cables everywhere–always. Your setup looks fairly neat. Thanks for the kind words on the twitch stream–will be streaming a new show this Friday.

has anyone tried r_e_c_u_r here? I’m interested to know if it can be made to run with the norns shield hardware. Seems like a great budget option since it can run shaders and other tricks.
