Cue markers allow bridging linear and non-linear approaches to composing music. The idea is that a user can set up entire cues, then place a cue marker on the timeline to launch a cue of choice at a particular point in time. The workflow is explained in more details in the Mixing Linear and Non-Linear Workflows section.

Adding Cue Markers

There are several ways to add a cue marker:

-click on the ruler creates a marker that launches the A cue.
-doubleclick on the rules creates a marker that launches the A cue, then opens the dialog to edit its name
Right-click on the ruler opens a menu where A to P markers are listed

Right-click menu for the Cue Markers ruler

Moving Cue Markers

Left-clicking and dragging moves a single marker to a new location on the timeline.

It is possible to move multiple markers by the same distance. Left-clicking each marker creates a selection of markers that can be dragged left or right together.

Single marker

Left-clicking and dragging moves a single marker to a new location on the timeline.

Multiple markers

It is possible to move multiple markers by the same distance. Left-clicking each discrete marker, or Left-clicking the first and last markers of a range of markers selects them, then dragging one to a new location will move all selected markers together.

Stopping All Cues

Ardour has a special kind of a marker that immediately stops all playing cues. This marker (Stop All Cues) can be added via the right-click menu on the Cue Markers ruler.

Removing Cue Markers

Right-clicking on an existing cue marker opens the context menu with a number of options. Choosing Remove will delete the cue marker of choice.

When all existing cue markers have to be removed, the best option is to right-click on the Cue Markers ruler (any place except an existing marker) and choose Clear All Cues. This will delete all cue markers in the session.

More Options

The context menu for existing markers provides several more options:

Set Cue:	Picking a cue from the list here will replace the selected marker with a marker for a different cue.
Locate to Here	This will move the playhead to the cue marker's position.
Play from Here	This will move the playhead to the cue marker's position and start playback.
Move Mark to Playhead	This will move the selected cue marker to the current position of the Playhead.
Glue to Bars and Beats	If this option is enabled, the cue marker will maintain its position in bars and beats even if there are changes in tempo and time signature.
