Hi Mark,
If your new lights are part of a conceptual group of lights, then you could just add them to that group and your existing programming would already work without modifications.
In the very simplest example, let’s say you are adding instruments and you want to make sure they are included in your “blackout” cue.
If your blackout cue is simply the command:
all = home
It will immediately do the correct thing the moment you add your new lights at the new venue.
In a slightly more complicated example, if you are adding instruments that need to function as part of an existing set of lights, let’s say something like “front fills”, then again there, if you add the instruments to the group “front fills” then any cue which has a command to set front fills will already be programmed correctly, without any modifications.
If your new lights need to have values that are unique to them, then they’d need to be programmed individually anyway, right?
