Primary / Backup Sync
Keep a second machine ready to take control.
Run the show from the Primary while a read-only Backup mirrors project changes, transport actions, and live playback over the production network.
Node:Cue / Primary
Operator control
The authoritative instance accepts show commands and sends each committed action to the Backup.
Synced
Project / transport / state
Node:Cue / Backup
Live mirror
The Backup follows in read-only mode and plays locally in parallel, ready at the current show position.
Primary lost
If the Primary PC or app crashes, the Backup automatically leaves read-only mode and becomes an immediately operable Standalone instance, preserving current playback so the operator can continue the show.
Audio-path switching remains under the operator's console, matrix, or hardware redundancy system.
