The moment has come where I can no longer trust the Blizzards I have and its time to purchase some extra lights. Mine only go out once a month or so. I am curious what you guys use for controllers the above set ups. I currently have a similar setup by my board limitation only allows me to pair lights instead of each individually.
I would look at a PC based solution. A flexible enough board is going to be north of 5k.
If you like learning programming languages (it's actually a macro language to be technical) the Jands 500's pop up under $500 and they have lot's of programmable buttons.
Really depends if the operator is PC kind of person or like consoles.
The biggest cluster f*** I ever saw was a guy trying to mix and do lights on 1 iPad. He did neither well.
