I'm planning a build, and think I want to use the Neo Pixel blade strips for lighting the blade. But, I don't fully understand how they work. I understand if I get a tri-cree for light that there are 3 LED's. With the Neo Pixel there are roughly 100.

Do I understand that:
1.each LED unit on the strip has red green and blue in it?
2. each 'unit' of 3 LED's is addressable and can be different colors?
3. Colors are controlled by the sound board?
(how do you set the colors?)
Will any board work for the Neo Pixel blades? For example, with the Nano Biscotte V4 work?
Do the Neo Pixel Blades 'need' or take advantage of better more advanced sound boards?

I guess this is a start to understanding what I need to buy. Thanks in advance for the help.
