"
For parameters marked with kAudioUnitParameterFlag_IsGlobalMeta, any
non-global dependent parameters are assumed to be dependent in every
element of their scope.

For parameters marked with kAudioUnitParameterFlag_IsElementMeta, then its
dependent parameters must all be the same scope, and are assumed to apply
only within a single element, not to other instances of the same parameter
in other elements.
"

Hope that explains it, I had some confusion with this myself on a previous
project.
