I ran into an issue with the “quadcast 2” microphone where I couldn't turn off the backlight on macOS, so I made a little utility for myself.
Maybe someone else will find it useful:)
It’s a bit of reverse engineering of the commands from NGENIUTY on Windows, with functionality stripped down to suit my needs—brightness adjustment (a few fixed brightness modes for simplicity), mode switching, and volume control. If anyone needs it, feel free to use it. I made it for myself, so for now I’ve only included the features I need, but maybe later I’ll get around to extracting all the commands and adding the remaining backlight and sound modes, plus an English translation. Works exclusively with the Quadcast 2 (haven’t tested it with the Quadcast 2S).
