Build a Cuelist

This guide builds a Cuelist from an empty list: adding cues, giving them actions, grouping, conditioning or repeating those actions, and organizing cues into sub-cues.

Before you begin#

Access to Cuelist in the left navigation.
The connections whose actions you plan to use, already added.

Create the Cuelist and its first cue#

Open Cuelist.
Create a new Cuelist, or open an existing one to add to it.
Select + Add Cue.
Name the cue and set its color so it's easy to identify at a glance.

Selecting + Add Cue again adds the next cue after whichever one is currently selected.

Add actions to a cue#

Select the cue.
Select + Add Action.
Choose an action, either from Recently Used Actions or by searching a connection's own actions.
Repeat to stack more actions in the same cue.

Actions in a cue's stack run based on the delay you set on each one: leave a delay at zero to fire together with the previous action, or set one to have it fire after a pause.

Group actions together#

To have several actions execute as one unit rather than as separate stack entries:

Select + Add Action, then choose ActionGroup.
Set the group to Sequential (one action after another) or Concurrent (all at once).
Add the actions that belong in this group.

Make an action conditional#

To have a cue's outcome depend on a live condition rather than always doing the same thing:

Select + Add Action, then choose ActionLogic.
Set the condition: a feedback state, or an expression testing a variable.
Add the action that should fire under When true.
Add the action that should fire under Else, if the cue needs a different outcome when the condition doesn't hold.

For example, testing whether the current hour is 12 or later lets a single cue set a light to full brightness in the afternoon and to half brightness in the morning, without needing two separate cues.

A condition can also test a connection's live state. To take a different action depending on whether upstream key 1 is on air on an ATEM connection whose Variable Key is ATEM, use this expression:

$(ATEM.pgm1_usk_1_onAir) == true

The ATEM. prefix is required. Written as $(pgm1_usk_1_onAir) == true, the expression can't be resolved and the cue always runs its Else action. Insert the variable from the expression editor's suggestions to get the prefix right. See Include the connection's prefix.

Repeat actions while a condition holds#

To have a cue repeat some actions for as long as a live condition is true:

Select + Add Action, then choose While.
Set the Condition: a feedback state, or an expression testing a variable. With more than one feedback, all of them must be true.
Add the actions to repeat under While true, and give at least one of them a delay.

Buttons checks the condition, runs the While true actions in order, and checks again, until the condition is false. If it's false when the cue runs, the actions don't run at all.

Warning

Buttons doesn't pause between rounds, so without a delay the loop repeats as fast as it can. A While also stops after 10,000 rounds, even if the condition is still true. An empty Condition counts as true, so it always runs to that limit.

See Repeat actions while a condition is true for an example.

Organize cues into sub-cues and reorder them#

Drag a cue onto another cue to make it a sub-cue of that cue.
Drag a cue between two others to reorder it at that level.

Cue numbering updates automatically as you add, remove, reorder, or nest cues: you never renumber cues by hand.

If you get stuck#

What you see	What to try
An action fires at the wrong time relative to others in the same cue.	Check each action's own delay: a zero delay fires together with the action before it.
A cue never does what you expect under certain conditions.	Confirm the ActionLogic's condition and that both the When true and Else actions are the ones you intend.
A conditional cue always runs its Else action, whatever the device is doing.	Check the expression for a connection variable without its prefix: `$(ATEM.pgm1_usk_1_onAir)`, not `$(pgm1_usk_1_onAir)`.
A While seems to fire all at once, or stops early.	Add a delay to an action under While true: without one, the loop doesn't pause between rounds and can reach its 10,000-round limit almost at once.
Dragging a cue reorders it instead of nesting it, or the reverse.	Drop directly onto a cue to nest it as a sub-cue; drop between cues to reorder at the same level.
