Sorry if I'm asking obvious, but I have yet another property which
usage is quite unclear to me:
kAudioUnitProperty_DependentParameters
The header says:
array of AUDependentParameter (read only)
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.
If the host is asking which parameters are dependent on certain Meta
parameter, where does it pass the meta parameter id? And how can AU
find out which meta dependent parameters host wants to return - does
the nonzero element value in GetProperty call mean I'm asking for
element meta?
Because I can't find it, I suspect the AU should return the array of
all parameters that are dependent on any meta parameter.
Best,
Palo Markovic
