New to the forum, One of the best things I've done is to convert an old PC keyboard to a foot controller, Take apart the keyboard and with a little soldering connect up foot switch to control the lights. It's just a matrix switch, connect any to wires form one side of the matrix and the other and it represents a key on the keyboard. And by using the Caps lock key you have 2 banks of switches available, Hooks to your PC by the usb cable for the keyboard.
You may have already done this but its great for running lights form stage
Thanks for listening, Happy New Year.
