  - in Options/Playback, set Cue Links to Disabled and Play Order to Random
  - in Options/Times, set XFade to 0%
  - Set Legend, set the chase's user number to 900

===== Explanation =====

This explains the functional steps within the sequence. For all the other XML details please refer to [[:macros:formats_and_syntax#xml_format|Formats and syntax]]

  * the ''<start>'' sequence is performed when the macro button is pressed
    * ''Playbacks.FirePlaybackAtLevel()'' flashes the chase
    * ''Chases.Play(userNumber:900)'' advances the chase. This works only if the chase is active, thus a pause is required
  * the ''<end>'' sequence is performed when the macro button is released
    * * ''Playbacks.FirePlaybackAtLevel()'' flashes the chase with level 0, effectively disabling it


===== How to use it =====

  * program a chase
  * in Options/Playback, set Cue Links to Disabled and Play Order to Random
  * in Options/Times, set XFade to 0%
  * Set Legend, set the chase's user number to 900
  * [[:macros:deploying|make this macro available]]
  * this macro needs to be __**moved**__ onto a handle. Copying it breakes it.
