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