Cubase AI and 3rd Party Plugins

As a follow up, Steinberg mention Blackworx on their site and talks about hundreds of plug-ins which work with AI, which led me to believe it would be fine, but someone on another forum last night suggested I’d need to buy another piece of hardware to make it work. I’m using the UR MKII interface and don’t really want to shell out for more hardware! Anyone? :slight_smile:
