'Low Prio Merge' is the default option. It means Low priority merge. It will only clone the values from fixture 1
when there's a values and where fixture 5 doesn't have any values already - it doesn't destroy any already
existing programming for fixture 5.
'Merge' will clone all the values from fixture 1 into fixture 5. If Fixture 5 had something programmed where
fixture 1 also had something, than the values will be the same as fixture 1. If Fixture 5 have something
programmed that fixture 1 doesn't , then these values will stay.
'Overwrite' will delete all existing values for fixture 5 and clone the values from fixture 1.
Here's some examples:
In your entire show you need fixture 5 to be a copy of fixture 1 and what fixture 5 had isn't needed anymore:
+ Copy (gives you the Clone command) Fixture 1 At 5 Please now select Overwrite on screen 1
In executor 3 you need fixture 5 to be a copy of fixture 1 and what fixture 5 had isn't needed anymore:
+ Copy (gives you the Clone command) Fixture 1 At 5 If Exec 3 Please now
select Overwrite on screen 1
In executor 3 you need the fixtures in group 2 to be a copy of fixture 1 and since we are not completely sure if the
fixture in group 2 is used already, then we should do a Low Prio Merge :
+ Copy (gives you the Clone
command) Fixture 1 At Group 2 If Exec 3 Please now select Low Prio Merge on screen 1
There's a very big range of possibilities when cloning. Please also have a look at the Clone command
