You can make a sequence to do this, though I don't see the benefit to lamping on one at a time.
Grab all of you fixtures, Lets say
fixture 1-60, then in in the control
parameter select lamp on, using the value layer, and on the delay
button(right next to value and
fade) type 0
thru 60. Store that as a
cue in its own sequence.
Run that sequence and it will lamp on one
fixture each second until all 60 are lamped on. You could also trigger and kill this with a
macro if you want to.
Make sure you reference a
preset for this lamp on, that way you can have multiple
dmx values for different
fixture types in the same
preset, and a simple update each time you change fixtures will will keep it working. If you are touring and have different lights each day, you will want to keep those
fixture in your patch section(you can unpatch them though) that way every time you have a rig with the same fixtures, your
macro will still work with no updates, as long as you had that
fixture in that file before.
