I make live visuals with a duo and our hybrid digital/analog setup includes an LZX Vidiot video synthesizer. Other tools we use (cameras, glitch and distortion devices, video feedback, Resolume) don’t involve video synthesis, at least strictly speaking. We stream regularly, but we’re not on Youtube.
If I had a proper interface like something from Expert Sleepers, I’d definitely connect Rack with my video synthesizer (it follows the Eurorack standard).
And it’d be fun to have a VCV video synth module…some months ago, @skybrian posted a proposal for a Video Monitor module in the Module ideas discussion. I’ve been too lazy to draft a proposal the right way in that thread, and I’m not even sure it’d make sense for VCV to host such a feature.
