Users can use the open-source VIA software to control the keyboard. You should visit the VIA software releases and download the software and of course the corresponding EPOMAKER mapping file as well. Then you should turn off the button Use V2 Definitions and load the EPOMAKER mapping file. The VIA software works in Linux, Windows, and MAC making it truly universal. Users can change all keys and create layers (up to four) to their needs, macros are also present and of course RGB lighting control as well. Everything you need is here with the power of Open Source software. There is no function to update the product firmware, but maybe EPOMAKER will release standalone files when this is needed.
