Open Sound Control 1.0 over UDP — the wire of the Miadi movement practice (Episode 083: body-worn device → /wek/inputs → Wekinator on destination port 6448), extracted from a one-off capture script into the one implementation.

• Strict encoding: f / i / d / s, big-endian, four-byte padding. Numbers encode as f by default — the Wekinator dialect.
• Total decoding: any datagram yields either a message or the fields that could be read plus a named parse_error. Nothing vanishes.
• The port lesson, kept: a listener binds the destination port; a sender's UDP source port is ephemeral and merely observed. The two are named distinctly everywhere they appear.

import { OscListener, OscSender } from "@miadi/osc"

const listener = new OscListener({ port: 6448, onPacket: (p) => console.log(p) })
await listener.start()

const sender = new OscSender({ host: "127.0.0.1", port: 6448 })
await sender.send("/wek/inputs", [0, 0, 0, 0, 0, 0, 0, 0, 0])
