Software
As soon as you installed Corsair's software, which you'll have to download from the manufacturers website first, you can start to program macros as well as change the lighting. When it comes to macros you can assign them to any key you like, which means you're not limited to different keys on this device. The software lets you modify the RGB lighting at your leisure, therefore you can configure pulse, ripple as well as wave effects. Basically it's only your imagination that could set limits to what lighting effect can be set.
