This produces synchronous events on Audio and MIDI ports.
One rvent per second, exactly at every second since engine-start.
MIDI: C-4 Note-on/off (1 sample long)
Audio: +1/-1 transition:
+1 in sync with Note-on,
-1 in sync with Note-off

optimize port lookup, adding/removing/reconnecting routes
...
xxxAudioBackend::connected_to() is called O(N^2) when building the graph.
Mitigate this by using an O(log(N)) lookup.
This duplicates the storage (both set and map and both are kept in sync.
Changing this to a boost:bidirectional might be nice, before updating
other backends.
