How about some display only controls?
One would be like the center section of a knob, but just have the number shown, and no output. Configure the same way as a knob, such as named ticks, etc.
Second would be just active line of a picker. Again, configured the same way as picker, but just shows single line, and sends no output.
Finally, toggle button, in essence a status light.
As display, prolly always be no touch in play mode.
