ardour doesn't do latency compensation for busses. maybe it should.
there is an implementation between:

  1) compensate by delaying playback onset of disk material
  2) compensate by using delay buffers

they each have their own plusses and minuses. right now, ardour uses
(1), and since busses have no disk material, they cannot be compensated.
