There are already changes so the button type 1 sets the "ion" value when clicked, but the orchestra is responsible for resetting the output variable once the state change has been detected. Alternatively, the output could alternate between the "on" and "off" states, although this is less intuitive. Outputting "ion" while the button is down, and "ioff" otherwise is also possible, but would limit the use of the button to the mouse only.
