Cues

Cues are the main component of every show/session. There are multiple types of cues able to perform different tasks, those can be subdivided in two main categories:

  • Media cues: used to play multimedia contents, usually related to some media file or stream
  • Action cues: used to accomplish more complex interaction (e.g. start multiple cues at one), fading other cues parameters or interact with external devices or application.

A cue can perform different actions depending on its current state

Actions:
  • start: Perform the cue task
  • stop: Stop the running cue
  • pause: Pause the running cue if possible
  • interrupt: Stop the running cue, other cues/functions will ignore this event
  • fade: Decrease/Increase gradually a predefined cue parameter (e.g. volume)

Every action (except for fading) can be performed with or without a fadein/out.

Cue options

Cue options can edited via a dialog, the way to access this dialog is described in the layouts pages. Options are organized in tabs depending on their context.
