Ask HN: We just had an actual UUID v4 collision...

import { v4 as uuidv4 } from "uuid";

const document_id = uuidv4();

Show HN: Mideo – Translate Video to MIDI

Fri, 05/08/2026 - 3:42am

Introducing MIDEO; a free browser-based MIDI controller built on top of the WEB MIDI api.

Connect it to your DAW (for example Ableton Live via the IAC MIDI Interface) and use video motion / color changes to control parameters, adding new layers of depth, movement, and unpredictability to your sound.

Very happy to hear your thoughts, ideas, and suggestions for improvements.
