Made a video using Gravity Waaaves! Having tons of fun exploring multiple layers of feedback with this super strange device.

I made an hour long generative ambient track (or generative system?) and used Resolume Arena to live process some video footage for projection. Unfortunately during editing I realized that the Arena output was too fast for ambient, so I used Final Cut’s machine learning algorithm to slow down the video which gave the projection some extra psychedelic flavor as it morphs between frames. It took me an entire weekend to make the generative project, record it, edit and render it, but I learned a lot so it was really worth it!

hello to the world (with fast glichy drum and bass)
(text made with GitHub - htor/framing: Online editor for live coding JS graphics with the canvas API. in a web browser → OBS screen capture → lots of effects layered and timed in Davinci. learned a lot and had a way too much fun !!)

Working on a utility comparator for eurorack video/audio. I’m designing it to drive a S/H module. I’ll probably do a V2 with stacked boards to reduce the width, though I’m about to send this off to be fabricated - my first circuit design - : )
V3 will use video rate comparators, for more in depth video capabilities.
If all goes well with the design I will have a few boards (no panel) spare. If anyone is interested to build one DM me. Either for a board or the gerbers. It’s all basic components. I’ll start a github page and store it there also.
thanks to @cyberboy666 for advice.

Hehe, I’ve been taking the first baby steps of controlling my V-4EX with my Digitakt. As I say in the description of this vid, I’m kind of embarrassed about how long it took me to figure out how to get it working. My reading of the manual made me think it was wayyy harder than it turned out to be.
Either way, when I got it switching inputs on command, I got excited and made this video. Simple, but a ton of fun to do.

My Quad Comparator board is completed and looking beautiful with panel!
I have one v1.2 board still, and 5 of the V1.3 boards (with small improvements to part layout etc) if anyone is interested. All Through hole common parts. I think yellow works best for the output status but any colour can be used.
The first input is buffered to the other inputs, so it’s possible to create different outputs from a single voltage using different compare settings. Any unpatched input will receive input 1, they are not cascaded downwards.
The Leds shine through clear sections mapped in the FR4 pcb material. I’m really happy how the panel and pcb came out.

had a good live AV gig recently, SD glitchy video, DIY FX rig, looper, etc. Some sync dropouts, repaired in edit (and now resolved) was a great show and the dropouts were not noticed by the assembled.

This looks sick!!
There’s a lot of terminology to take in for a novice like myself.
Is a utility comparator a module that compares two signals and produces an output based on their relationship? And is that output then used to modulate visuals based on that input?
Hi,
Thank you, very kind!
You are correct, that’s how it works - the only thing is that one signal is internal, a reference voltage.
Comparators are good for conditioning signals to go into logic gates and other inputs where a strict 1 or 0 is expected.
You can use this comparator to modulate video control signals, though the comparator in this design is not a video rate comparator (so it can’t process very high frequency of video directly). It’s kind of in between audio eurorack and video eurorack.
Comparators are used in keying and paint effects, and colorisers.
I’m working on some other logic modules at the moment too. A comparator with video rate, and some classic AND/OR/XOR gates.

A family of digital video effect boxes.
Currently I have four stand-alone units (one for video sources, another is a pair of circular buffers for recall and looping, a box of effects, and a utility box for fixing and preserving aspect ratio which takes a SD 4:3 and places it correctly in 16:9 with nice effects around the egdes) but eventually there will be more and versions of each that will be eurorack mountable with CV in.

very cool!
I’m working on a tutorial for new databending techniques. Here’s the original video
And a few examples of databending the video.
Tutorial will be published in 2025 once I’ve finally rebuilt my website! This’ll be a follw-up to my 2009 databending in audacity tutorial. Only took 16 years!

Have you looked at this? GitHub - jmtrivial/rawdodendron: An audio/image converter using a raw approach
I also have been working on a desktop app using his approach and the python pedalboard library for videos rather than images, using multiprocessing for speding things up
Heres my repo however much messy, hadn’t planned on sharing it but always open to collaborate. It is very much not finished though and I don’t have a formal programming formation lol

I’ve been working with the Sega Genesis lately. Realizing that it has a 68000 I thought it was a little computer. Had an idea to turn it into a audio reactive visual synthesizer. Going to make it open source and create a how to build PDF. Calling it VIDEON cause like Video - on … Videon. Hoping to write 100 different Visual patches. All of which would be Audio Reactive and you would use the Sega Controller to adjust the Visual parameters.
You would plug audio into the cartridge using an Aux cable, the stereo audio would be divided into two channels running through the MSGEQ7 chip which would also divide both left and right channels into Low, Middle and High frequencies the STM32 would take that data and create visuals using the data and the Sega Genesis 68000 CPU. Oh and it has an Audio Out so you can plug your music back into speakers. Also hoping to add an SD card port so people can make their own Visual patches.
Once done hope to make a Super Videon for the SNES.
