Hi. I am trying to wrap my head around state and preset management in AU
world and have a few questions...
Is the host responsible for keeping track of and saving data of any user
presets, and the AU is responsible for saving its factory presets?
Is it expected that factory presets can be modified?
If so, is the host responsible for saving and restoring those
modifications?
If not, is it expected that a factory preset, once modified, becomes a
user preset?
In DispatchSetProperty for case kAudioUnitProperty_CurrentPreset, there is
a notification mechanism for when the incoming preset is a factory preset
(NewFactoryPresetSet is called), but not for when the incoming preset is
a user preset. Please discuss...
Thanks,
Marc
