I downloaded the OS, extracted the files to my SD card and plugged it in. When I power the keybow up, the only keys that light up are the green indicator light and then one other. I have tried with another SD card and I get 1 green and 3 blue keys lighting up. I understood from the instructions that the whole thing is supposed to be lit up. I do not understand what I am doing wrong. I got my Keybow OS here:
My SD card is FAT32 (I have tried two separate SDs), and my Keybow is assembled.
