That's what I always say: make your cues for a small different group 
of lights, and run them in different layers, e.g.

Use layer B, C and D for different groups (non-overlapping channels)

Additional you could use layer E as a background (all channels), so 
the cues running in A-D are overruling your background only for 
overlapping channels.

Use layer A for blackouts and flashes as it overrules all layers.

Above can made if you remember that a cue is one or more steps ending 
in a hold for ever. Only the 70% of a scene is difficult :-)  I used 
a blackout with a transparency of 70%, maar better is to have a 
separate cue with 70% values.

Your cues (assume cuelist 99.1 is blackout, 200.1 & 200.2 are the 
scenes, and should it be run in B or lower):

// Cuelist 200 (14 steps), stored 06-03-2005 14:58
  -- cue 1
  go 99.1 in layer A
  hold for ever
  -- cue 2
  reset layer A
  show d06 for 0.05s, crossfading for 3.0s
  show d07 for ever, crossfading for 3.0s
  -- cue 3
  set layer A to mix transparent from 100% to 70% in 3.0s
  go 99.1 in layer A
  hold for ever
  -- cue 4
  reset layer A
  show d14 for ever, crossfading for 3.0s

:d06
    1[255]

:d07
    2[255]

:d14
    2[255]

BTW multiple solutions are possible as usual, but keep in mind that 
if you want to built a scene from different parts, you must either 
load those scenes sequential (0.05s hold time) in one layer or use 
different layers. I chose for sequential in the example as it is a 
nice mix of techniques :-)

As said the 70% solution is not great, as you get a problem when you 
want to remove it again. If you do what I did in cue 4, your 
crossfade of d14 will not work. You can prevent it by using a "set 
layer A to mix transparent from 70% to 100% in 3.0s" and then reset 
layer.

You can further remove the two scenes from this control list by using 
"show 200.1 for ever" (referencing a scene).

Note: Use alt-space bar to skip a cue, and alt-PageDown for previous cue.

If anybody has better ideas, please let us know.
