52 This handles the plugin duties, and the midi encoding and decoding,
53 and the signal callbacks, mostly from ARDOUR::Route.
55 The model of the control surface is handled by classes in controls.h
57 What happens is that each strip on the control surface has
58 a corresponding route in ControlProtocol::route_table. When
59 an incoming midi message is signaled, the correct route
60 is looked up, and the relevant changes made to it.
62 For each route currently in route_table, there's a RouteSignal object
63 which encapsulates the signals that indicate that there are changes
64 to be sent to the surface. The signals are handled by this class.
66 Calls to signal handlers pass a Route object which is used to look
67 up the relevant Strip in Surface. Then the state is retrieved from
68 the Route and encoded as the correct midi message.
