I guess I'd probably make a visitor that goes out and located the nodes you want by name, and attaches similarly-named sounds to them? That way wherever those nodes are in the model, they get their appropriate sounds. > Also, is there any detailed documentation for this system?

Every significant class has Doxygen-type comment documentation embedded in the source. That, coupled with the examples, is all there is.
