QPAD KEYBOARD SOFTWARE
Head over to the official QPAD website to download the latest firmware update and software version.
Updating the keyboard firmware takes just a couple of minutes.
The software is very plain (and easy to use) and allows you to switch between the 5 profiles and PC mode, remap the keys, adjust RGB illumination (either for all the keys or per-key) and create/record macros which you can then tie with any of the keys.
Here you can see the lowest and highest brightness level for the keys of the MK-90.
Some of the available colors and effects of the MK-90 are also showcased above (including a custom one).
