# Protocols: OSC, MIDI, and LAN sharing

> Connect Relay to your production environment through OSC, MIDI, LAN sharing, audio metering, and transcription tools.

Relay supports a range of protocols and network features that let your dashboard communicate with the rest of your production environment.

The incoming MIDI and OSC setup experience is centered under `Relay > Settings` → <Icon icon="radio" /> **External Control**, where you can monitor messages live while building automations.
