Hello!
I'm working on an AudioUnit that needs to change some parameter and
property attributes at run-time, like min/max value, etc.
It seems to make sense to use a call like:
PropertyChanged(kAudioUnitProperty_ParameterInfo,
kAudioUnitScope_Global, 0)
from the AU. However there doesn't seem to be a way to indicate WHICH
parameter has had it's parameter Info changed, and it seems wasteful
for a view to have to query all parameters to figure out which one is
changing. It's tempting to use the ElementID as an index to the changed
parameter, but that doesn't seem to square with the definition of
ElementID.
Any suggestions?
