So the RT / RD is sort of a Mellotron type system (and I mean this in the best way) rather than a physical modeling system (like for example Yamaha and others do for synthesis). I'm just speculating in reference to complex modeling... I'm thinking of the sort of algorithms that BiB must have for applying styles, but perhaps scaled up to the sort of super-Mellotron system that RT /RD might use. I've only played with these a bit; it hasn't been the focus of what I am interested in right now, but I'll be looking at them more down the line.
