When you right-click a cue, you can bring up a dialog box and edit the CUE PROPERTIES. There you will find settings to control whether animations are beat-based or time-based.
However, sometimes the beats-or-timing is dedicated to effects themselves, not the animation or cue properties, as Bart indicated. In such cases, simply click on the cue with the left mouse button to select it or start it. Then the EFFECT EDITOR tab on the right will show you all of the effects. Each separate effect may be time-based or beat-based, and this is selected with the metronome or stopwatch icon that is seen.
Please let us know if you have any other questions.
Best regards,
William Benner
