* makes it show only busses, or only MIDI tracks. At that point, the
* ordering on the surface differs from the ordering in the GUI.
*
- * The ordering is given via a combination of an object type and a
- * simple numeric position within that type. The object types at this
- * time are:
- *
- * Route
- * - object has inputs and outputs; processes data
- * Output
- * - Route used to connect to outside the application (MasterOut, MonitorOut)
- * Special
- * - special type of Route (e.g. Auditioner)
- * VCA
- * - no data flows through; control only
- *
- * Objects with a numeric order of zero are considered unsorted. This
- * applies (for now) to special objects such as the master out,
- * auditioner and monitor out. The rationale here is that the GUI
- * presents these objects in special ways, rather than as part of some
- * (potentially) re-orderable container. The same is true for hardware
- * surfaces, where the master fader (for instance) is typically
- * separate and distinct from anything else.
- *
* There are several pathways for the order being set:
*
* - object created during session loading from XML
