I have been working with computers and technology for years and I can assure you that hardware is NOT the hardest nut to crack, for the simple reason that it doesn’t change, whereas software can continually move the goal posts.
As to your UAD card it is no different the Pulsar II card in that the plug-in will not work without it. (It’s the sound engine)
As an example; if somebody cloned the software in your G70, it would be of no use to them without the Roland sound engine, so there is no point in cloning the software.
Styles are just Midi loops, and so cannot be tied to hardware. (Unless you strive to undo the universal communication that has been continually developed for the last 25 years)
