There are three kinds of OSC in CuePilot.
Track OSC is the use of OSC Tracks to add OSC Cues to the Timeline to control specific devices/systems. You can expand on the included OSC Schemas with your own custom OSC Schemas.
Live OSC is the function of CuePilot sending OSC of every Cue in a Timeline as it is being played, live, for other systems to listen for.
CuePilot Remote is a function in CuePilot for allowing remote control of CuePilot, so that a second instance of CuePilot can be running in sync, allowing additional collaboration as well as redundancy.
