CORSAIR UTILITY ENGINE
As usual you will need to visit Corsair's support page to download the latest version of their Utility Engine unified software (CUE).
The first thing this software will do once installed is to check and see if your keyboard has the latest firmware version installed and if not it will ask to update it (the process takes less than a minute to complete).
Corsair redesigned the CUE software since we last used it with the K70 RGB but you can still access most of the functions through here so you can assign actions to each of the 110 available keys (macros, text, keystroke and others), adjust the color and effect (5 available ones) for the keys (per-key illumination is also supported), set the keyboard lock button functionality, create your very own lighting effects and of course you can also record macros (you can save up to three profiles on the keyboard).
Here we've placed several of the available RGB effects one can use with the Corsair Utility Engine (including the custom one we made in CUE).
