13.5 Loops and Links

Normally cues in a cuelist will be replayed in numerical order, but you can use links to change this. Links can be used to jump to other points in the cuelist, or to create loops.

Unlike some consoles, Hog 4OS creates a link as a special type of cue, rather than an attribute of an ordinary cue. Because it is a separate item in the cuelist, you can move cues within the list without disturbing the link.

[Tip]Tip

When a cuelist gets to the end, it will link back to the first cue by default, so there is no need to put a link in.

13.5.1 Creating a Link

To create a link:

  1. Open + [Cuelist 1] : open the cuelist window.

  2. Play the cues in the list until the current cue (shown by -> in the wait column) is the cue before where you want the link.

  3. Click on the Insert Link button in the window. The link cue will be inserted after the current cue.

  4. Select the Fade cell of the link.

  5. Set [cue number] Enter : assign the cue number to be linked to.

You can delete link cues in the same way as any other type of cue. For example:

  • Cue 3.5 Delete

13.5.2 Creating a Loop

To create a loop, you need to have two things:

  • A link that points to a cue earlier in the cuelist.

  • All the cues in the loop (between the linked-to cue and the link cue) must be assigned with wait or follow triggers; see Cue Wait Timing.

Hog 4OS will recognise this as a loop; see Figure 13.11, “A Cuelist with a Loop”.

Exiting Loops

You can determine when the cuelist stops looping and continues with cues after the loop. The options are:

  • Forever: the loop will run indefinitely until you press the Go key.

  • Count: the cuelist will loop the assigned number of times. Assigning a count of zero will make the cuelist ignore the link.

  • Timed: the cuelist will loop until the assigned time period has elapsed.

To assign the looping behaviour:

  1. Open + [Cuelist 1] : open the cuelist window.

  2. Select the link cue's Delay cell, and press Set.

  3. Select an option from the Loops Toolbar:

    The loops toolbar
  4. If you have selected Count or Timed, enter a count or timed value.

You can also configure what happens when you press the Go key during a loop; see Action of go when Looping.

13.5.3 Tracking Through Loops

By default, Hog 4OS's feature ensures that, when you use links to change the order of cue playback, the cues appear on stage as if they had been played back in the order they appear in the cuelist.

Sometimes, however, you might want to track through links rather than maintain state. For example, you are creating a loop where the first time through you want the four fixtures to come on one at a time, and throughout the loop you want them to alternate colour between red and blue. To do this, you might plot:

Cue

Fixture 1

Fixture 2

Fixture 3

Fixture 4

Int.

Colour

Link to Cue 1

The idea is that the intensity of the next fixture is brought to 50% in each cue, and that these values then track through for the duration of the loop (shown by the arrows). However, because of the Maintain State function, when the cuelist loops back to cue 1 Hog 4OS will make cue 1 look as it would have if you had run the cuelist in order. The result is that fixtures 2 to 4 will go out, just as they were the first time round the loop.

To stop this happening, you need to enable Track Through Loops, in the Cuelist Options window:

  1. Open List 1 : open the cuelist window.

  2. Press Options and select the Track Through Loops tickbox.

Note that Track Through Loops also applies when the cuelist automatically loops back to the start of the list after you play back the last cue in the list.

[Important]Important

The Track Through Loops option applies to the whole cuelist. Using it may have unintended consequences when playing back other cues in the cuelist out of sequence.
