Miasmus Can it do that cool thing where it makes a color wave when you press a key?
Yes. I currently have the color set to white.
Miasmus Also, what keyboard? I am in the market for a new one
The one I got is a SteelSeries Apex 5. It's got a little screen on it which is neat. They have an API documented on GitHub that can be used to show stuff on the screen or change what the keyboard looks like, though you need their engine to pull it off. Nonetheless, it still works with OpenRGB to an extent without their engine.
