<!--
  prerequisites: 
  - 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
  - this macro needs to be moved onto a handle. Copying it breakes it.

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

• 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
• make this macro available
• this macro needs to be moved onto a handle. Copying it breakes it.
