Follow and Hang on Eos

Symptoms/Issue

In Eos cue programming, what is follow and hang and how do I program them?

Explanation of Concepts

The  follow/hang portion of the Eos Family Online Manual can be found here

Follow and hang are both ways to automatically have the next cue in line execute when executing the cue before it.

Ex: Cue list has cues 1-10. If you want cue 8 to automatically execute after cue 7, you can apply a follow or hang to cue 7.

With Follow, the countdown starts as soon as you execute the initial cue.

Ex: Cue 1 has a duration of 5 seconds and a follow time of 2 seconds. When cue 1 is executed, the next cue will start playing after 2 seconds, even though cue 1 still has 3 seconds left to complete its transition.

With Hang, the countdown begins once the initial cue has completed its duration.

Ex: Cue 1 has a duration of 5 seconds and a hang time of 2 seconds. When cue 1 is executed, the next cue will start playing after 7 seconds, as it must wait the 5 seconds of the initial cue completion and the 2 seconds of the hang.

Follow and hang are applied to the initial cue, not the one that will follow it. If you want cue 8 to activate automatically after cue 7, you apply the follow or hang to cue 7.

Syntax/Programming

For Follow

  • Cue list has cues 1 and 2
  • Cue 1 has a duration of 10 seconds, you want cue 2 to execute 5 seconds after cue 1 begins to execute
  • Syntax: [Cue] [1] {Fw/Hg} [5] [enter]
  • This creates a follow of 5 seconds for cue 1
  • In the PSD tab, you will see F5 under the Fw/Hg column for cue 1
  • When cue 1 is executed, after 5 seconds cue 2 will automatically begin to execute (cue 1 will still be executing at this point)

For Hang

  • Cue list has cues 1 and 2
  • Cue 1 has a duration of 10 seconds, you want cue 2 to execute 5 seconds after cue 1 finishes executing
  • Syntax: [Cue] [1] {Fw/Hg} {Fw/Hg} [5] [enter]
  • This creates a hang of 5 seconds for cue 1
  • In the PSD tab, you will see H5 under the Fw/Hg column for cue 1
  • When cue 1 is executed, after 15 seconds cue 2 will automatically begin to execute
