Expected - nodes can broadcast their parameter changes via the 
media_server, using the BroadcastNewParameterValue() call, 
which is really a good thing, since it means all your views of that 
node will remain current/consistent; ie displaying the real value of 
the parameter.

The nodes supplied by the driver (ie most of the Be nodes, certainly
the emu10k driver...) don't implement the above notification 
functionality. Since there's no 'obligation' to do so, its acceptable,
but does seem a bit inconsistent, and is not really a 'solvable' problem,
except to make sure that new nodes do implement the call.
