When organizing objects in the Project Explorer > Audio tab hierarchies, I prefer to use Actor-Mixers instead of Virtual Folders because it allows me to have hierarchical control over the children (overall volume control, default output bus, default RTPC behavior, etc.). Whenever I see people using Virtual Folders, I recommend they use Actor-Mixers instead. Here's my question: In what circumstances are a Virtual Folder preferable over an Actor-Mixer? I can't think of any situation in which I'd want to use a Virtual Folder.
