I posted Jan 22, 2007 this on the list:

Make a control cue to start and fade-in the chase, and another one to 
fade-out and stop it:

To start chase 99, run 10 in any other free layer.

 // Cuelist 10 (2 steps), modified 22-01-2007 19:13
  set layer A to mix transparent from 100% to 0% in 10s
  go 99.1 in layer A


To fade out and stop a chase in A, run 11 in any other free layer.

 // Cuelist 11 (3 steps), modified 22-01-2007 19:15
  set layer A to mix transparent from 0% to 100% in 15s
  hold for 15s
  go 0.0 in layer A

Yes, there is a trade off when choosing separate layers for colour, 
gobo, movement, dimmer, etc, instead of combined cues.

If you are working well organized, it's worth to split it into 
layers, as it provides maximal flexibility. Also special for moving 
heads, with two extra layers (add & transparency), you can even make 
your path moves dynamically resized and positioned (like on a Euro 
10.000 up Hog :-)

On the other hand combined cues are simple, you can copy them, change 
a bit, and save it as another cue/chase.
