Alternatively you can use the Unfold function to delete a step 

from a chase. 

 

When a chase is first programmed, each cue in the chase has 

identical timing. This is called the global timing for the chase. If you 

want you can then set each cue to have its own timings using the 

Playback View window or Unfold. This is described in the next section. 

To set speed, press [Speed] then type the new speed, then press 

Enter. The speed can be set in Beats Per Minute (BPM) or seconds 

depending on the user settings.  
To set crossfade, press [Xfade] then type the fade from 0 – 100 and 

press Enter. 0=no fade (the chase will “snap”), 100=max fade (the 

chase will move continuously from cue to cue) 
When in Run mode, you can set the chase speed of the connected 

chase by tapping the [Tap Tempo] button in the main menu at the 

speed you want the chase to run.  (The option only appears when a 

chase is connected). You can also assign the blue or grey handle 

button to be a “tap tempo” button using the Key Profiles option (see 

section 11.2.1 on page 117). 
The Overlap functions allow you to offset and overlap the timing of 

changes in the chase. This can create really amazing visual effects 

with hardly any programming. The best way to learn about overlap is 

to program a chase with two cues involving several fixtures, then 

experiment with the overlap settings to see the various “roll” and 

“peel off” effects which result. 
The following diagram shows you the effects of cue overlap, fixture 

overlap and attribute overlap in chases.
