Software support for the AQIRYS ADARA keyboard can be found on the AQIRYS support page—simply search for ADARA here to find the installer. The latest version at the time of testing was v1.2 and it downloads as a ~2 MB compressed archive that simply contains the installer file. Running it triggers the installation process seen above albeit there are terms & conditions for you to agree to. The final install is under 5 MB and is extremely light on system resources.
Be sure to have the keyboard connected to your PC before opening the program else all you will get is an error message. Once done, the software drivers immediately recognize the ADARA—no surprise given they are specifically made for this keyboard—and open the home page we see here. There is no settings tab or a maximize window option although it does seem to scale relatively well with your display resolution and Windows scaling level. I did not experience any bugs in use and everything seems to be well-laid out from a user interface perspective. I just wish AQIRYS toned down the contrast on the on-screen keyboard here since it is jarringly bright to the point of making it hard to identify some things on the keyboard.
The video above goes through the general functionality of the ADARA software drivers, including the ability to create, edit, delete, and assign software profiles. The default tab pertains to lighting wherein there are several pre-programmed effects to choose from in the drop-down menu on the bottom left corner. Effect-specific options are in the middle, including with discrete steps for overall brightness and speed, and the exact color(s) are seen at the right where you have 16.8 M colors to choose from. The Key Setting tab helps with key assignments and there's also a fully-featured macro editor and recorder too. Finally, you can choose to have the LEDs on the keyboard be synchronized with any music being played on the device which in turn means you are passing on some extra data to the software. Feel free to play around and tinker with the keyboard as there is a handy reset button here which takes a few seconds to get back to the default operating state.
