Relay can receive and send OSC messages over the network.

​
Enable OSC receive

  1. Open Relay > Settings.
  2. Select External Control.
  3. Switch to OSC.
  4. Turn on OSC Listener.
  5. Set the listen port.
  6. Point the sender at this Mac’s IP and that same UDP port.

​
Use OSC in Relay

  • Use OSC Receive triggers in Automation View
  • Use OSC Send actions in Automation View
  • Use OSC from Button modules when configured
The External Control page also shows the current IP address, message counts, and the most recent OSC packet so you can validate traffic before wiring it into a graph.

​
Troubleshooting

If packets do not arrive, confirm the sender IP target, port, Local Network permission, and that no other app is already bound to the same port.
