HERA CONTROL SOFTWARE
Since GAMDIAS much like every other manufacturer doesn't offer a software CD in the bundle you will need to download the HERA control software from their support page.
The program does not install so wherever you decide to decompress it you will also need to run it from and wait until it's done identifying the compatible device(s) and download the available controls.
GAMDIAS offers one of the most comprehensive control panels i have ever seen that allows you to remap all of the available buttons, program the 13 available macro keys (in the 10 available profiles), create macros, adjust keyboard illumination via 6 levels (the last one is the typical pulsating one), assign sounds and timers to each of the keys, edit the sounds and timers you'd like to use, check the how many times and how fast/hard you've pressed the keys (stats) and you can also check the FW version (there's also a Olympics tab which was blacked out). Of course as you can see from the screenshots the control panel needs some work since at first it was hard even for us to navigate it (the font doesn’t help).
Here you can see the lowest and highest brightness levels of the keys.
