Thanks for the reply!
That is basically where I am now. I can link one or several masks to one or several of Soundkeys outputs. But that means that the light or lights in that particular mask will always be triggered.
I’m looking for a way to alternate, or randomise the output between many masked lights.
I would actually be fine with drawing 300 masks, but I don’t know how to tell After Effects to pick a random mask for a light flash, or two, and then automatically picking another.
Does that make sense?
