This will be my second year using RGB. My first year was some flood lights with 3 channel controllers. This year I would like to use some smart pixels, specifically the ones from Lights, Music, Magic. I really liked the way the lights worked in this video:https://vimeo.com/22643691# I have been corresponding via email with them and they tell me that I do not need a pixel controller for this. This confuses me as everything I have read discusses the use of pixel controllers (sending commands to the ic chips) when using smart pixels. I have asked them to explain this but their reply was simply that you don't need one. So how does this work? Do some smart pixels need controllers and others don't? How would it work without one? I have got most of my information from the very excellent primer "The AusChristmasLighting 101 Manual.
