Thanks guys,
Scott that is correct, the joys and everything to the left are connect to the same sound board you recommended in WannabeJoy’s build. The 6 square buttons on the right turn off when pressed. As for the cover switches and the emergency stop, they certainly do nothing out side of the imagination.
Also, I removed the center covered switches and replaced it with a 1/4 inch head phone jack. I’m looking for a head set with a mail 1/4inch when I pop into thrift stores but for now an adapter will have to do.
