(edi-41): Addition of "bus" concept.
- submitted: kaiv, 13.11.2005

------------------------------------------------------------------------
Details:

[background: what]
- problem of "loop" objects
- currently "loop" objects can be used to route audio
between chains
- loops however add delay to the processing chain

[rationale: why]
- make it easier to create more complex configurations
- avoid unnecessary processing delays in complex
configurations due to loop objects
- concept of "buses" is familiar to many users (something
to which you mix multiple sources of audio)

[description: how]
- list of goals/requirements that should be reached
- a new bus audio object type, based on current loop
object code
- changes to engine allowing to process the busses
without additional delay

[todo-list]
- add the "bus" object type
- engine optimizations
