I'd love to be able to get a 4 button expansion switch with the same visual feedback as my GT-10's built in switches. I know you can add two 2 button switches that can do anything that the built in switches can do. But of course, there is no visual feedback. I don't know if it would be practical for RJM to build and sell, but it sure would be nice to be able to turn my GT-10 into a GT-14.
