I have it already like that when testing so sure if you want all the lights to act as one effects , I am not sure if the word segments in the post subject means to be able to only have all units with same effect ( or also control each segment or unit with different effects from central place ) . if that is the former then it is simple to do this way without the ddp mess i guess . I am an advocate of DDP because I use it a lot so do not be surprised to see we use it for a lot of tricks
