Open Sound Control, AKA OSC, lets you create and control sound, graphics, lighting, whatever audio-visual delight you can imagine.
It's a geeky-techie technology but you don't need to be a geeky-techie person to use it.
Make no mistake; geeky-techie people are obviously very cool, but not everyone wants to be one. Here's the good news: you can use OSC to make wicked cool stuff without having to bury your head in endless tech tomes.
The book is available for purchase in PDF, mobi, and epub formats. You get all three formats when you buy the book
OSC connects you to an endless array of controllers and multimedia devices.
Just the Best Parts: OSC for Artists, written by artist/musician/programmer James Britt, will give you the tech chops you need to get rolling with OSC.
It's fun, it's fast, it to the point.
