Are FMOD\_STUDIO\_PARAMETER\_IDs fixed? Can I hardcode a known parameter ID into my code and it won’t ever change based on adjusting options on the parameter or between different bank builds/platforms? Or is there a way to get a non-global parameter ID by name from the Studio API without an EventDescription? According to the docs, Studio::System::getParameterDescriptionByName only seems to be for global / mixer parameters.
