This is a long one! I've been wanting to do a detailed explanation of the QMK port for EVision/Sonix keyboards for a while now and this is it. In this video, I describe what Sonix QMK is and then demonstrate installing it on my Redragon K556 keyboard. I compare the RGB effects from the stock firmware against what you can achieve with QMK, including audio visualizer and game integration. I also show how to revert the keyboard back to the original firmware.
