description: releases a playback (and skips if this playback doesn't exist)
remarks: here, the IsClaimed condition is the important part as trying to release a playback that doesn't exist would throw a Null Argument exception, see link above.

affected properties

Code

<step condition="Handles.IsClaimed("cueHandleUN=1")">
  Playbacks.ReleasePlayback(userNumber:1,  Playbacks.MasterReleaseTime, true)
</step>

Explanation

This explains the functional steps within the sequence. For all the other XML details please refer to Formats and syntax

  • Handles.IsClaimed checks whether a handle exists
  • if it exists, Playbacks.ReleasePlayback releases this handle

The idea was to pre-define a number of handles which would be released by macro.

How to use it

Snippet only - adapt and us in your own macros.
