Hello!
I’m sure this is an easy question to answer, but I can’t seem to find the answer in the docs. I want to load an AudioUnit preset into an AudioPluginInstance. I see the methods for loading VST presets with the VSTPluginFormat and VST3PluginFormat classes, but nothing obvious for AudioUnits. How do I do this?
Thanks,

Bump! Still looking for an answer. I would be grateful for any help!

Do you want to manage your own presets of your own AU plugin or open an AU plugin and access the presets of this plugin?
Hi, thanks for the response! Currently, I would like to be able to load an .aupreset file from disk. But I would also be interested in learning how to access the presets of the plugin as well. For reference, this isn’t a plugin that I’ve created, so not my own AU plugin.
Well, each plugin can have its own format, it seems to me, unless it’s an xml named with a different extension, what you’re talking about is reverse engineering to my knowledge. For that, I would start by opening it in a text editor to see if I recognize xml and if not a Hexadecimal editor with patience and a test preset or I would move the values one by one…
You can also access each automatable parameter as in the example named audiohostplugin.
