 Ardour's structure is object oriented. The main object is the Session. A Session contains Audio Tracks, Midi Tracks and Busses.
 Audio and Midi tracks are derived from a more general "Track" Object,  which in turn is derived from a "Route" (aka Bus).

 Object lifetimes are managed by the Session. Most Objects cannot be directly created, but one asks the Session to create or destroy them. This is mainly due to realtime constrains:
 you cannot simply remove a track that is currently processing audio. There are various <em>factory</em> methods for object creation or removal.
