How to do Chase

You don't need to use cue lists for effects.

Just go into the effect tab and create an absolute effect.  Put 2 steps in it set the step time of first step to 1 and other step to say 2.  in the level of the first step put either an actual level or a colour pallete,  leave step 2 as Bkgrd (meaning it will be what the fixture was add prior to running the effect).

Then in live just pick a group of fixtures and enter effect and the number of the effect you created.

eg type Group 1 Effect 1 and the chase will run across all the fixtures in the group,

In the effects tab theres a bunch of other buttons on the right to modify how it behaves and speed.

Also if after entering Group 1 you press Offset before entering Effect 1 you get the options to run the effect in reverse, random, mirrored etc. 

Element can only do one cue list.

Other Eos family consoles can do many cue lists.

This might help with effects:
