Open Sound Control (OSC) is a lightweight UDP-based message protocol widely used in live performance, theatre, and installation art. If your show runs QLab, Resolume Arena, TouchDesigner, or any OSC-capable software, Cueva Control can talk to it directly.

Adding an OSC Send node

In the flow editor, drag an OSC Send node onto the canvas. Set the destination IP and port to match your target software. Then define the OSC address pattern (e.g. /cue/1/start) and any arguments the message should carry.

Receiving OSC

The OSC Listen node opens a UDP port on the device and fires the flow when a matching message arrives. Use the address filter to match specific paths, or leave it blank to trigger on any incoming OSC message.

  • Set listen port in device network settings
  • Filter by address pattern or wildcard (*)
  • Access message arguments as flow variables
  • Combine with condition nodes to branch on values

Make sure the RELO IO8 and the target machine are on the same VLAN or that UDP is routed between subnets. OSC does not traverse NAT by default.
