Sync Eater

Analog visual glitch effects processor

June 14th, 2021 Development progress update (click)


V1 Prototype

The Sync Eater is an analog video effects processor with a focus on glitches and visual experimentation. This personal prototype, built into an abomination of an enclosure, was made using the first round of prototype boards. The finished version will feature PCB mounted controls, a standardized front panel, CV implementation, and maybe a few other features. Will be released sometime soon-ish.

Not reinventing the wheel here - there’s other gear out there that does similar stuff. This started as a personal side project and I ended up enjoying putting together my own take on this sort of device.

Works great with CRTs. Will also work with video mixers, composite capture cards, etc… but as is the case with other glitch devices, capture cards benefit greatly from the addition of a time base corrector to avoid signal loss. The dry/wet knob on here helps to mitigate this issue with capture cards while still allowing plenty of effects to get through, but a TBC should be used in a live setting where stability is paramount.
