You have what we call a Meta parameter - that is changing the value of
this parameter can change the value of other parameters. So, you
should be flagging this parameter as a meta parameter. Also, you can
describe to the systems which parameters your meta parameter can
change, which can lead to some nice efficiencies.
AudioUnitProperties.h has some more info.

I have a couple of parameters that I want to just display values to

SetParameter updating these extra info parameters when the controlling
parameter changes.
When the display parameters only have the flag _IsReadable, the
display
does not update. If I have it _IsReadable | _IsWritable the sliders
move
as the controlling slider moves.
As I've read, read only parameters are supposed to be used to
present the
user with info, how do I get the read only parameters to update?
Thanks,
