From the project
The Synkie is a modular open source analog video processor, developed by Michael Egger, Max Egger and Flo Kaufmann
The Synkie is a modular open source analog video processor, developed by Michael Egger, Max Egger and Flo Kaufmann. A bit like the venerable modular Moog synthesizer it lets you toy around with the signal using patch cables – but this time not producing sound but images. It is an instrument for video, a playground, a platform to explore new ways to transform a video signal. Synkie is still in development, we constantly develop new modules – and even the base specifications may still change over time.
