SynthesiaKeyboardLights
This is a simple app that lights up a Corsair RGB keyboard to the Synthesia app! It uses CUE.NET to talk to Corsair keyboards, and image capture to find the virtual piano on-screen and lights up the keys.
Demo
Tested on Synthesia 10.9.5903 with a Corsair K70 RGB MK.2 SE keyboard.
