Using Virus B to control XL via Midi?

[Arndt]

Hello everybody,
I'm new to this forum and have got the first question regarding those wonderful instruments called Virus...
I own a Virus B and have an opportunity to get a Virus Rack XL for a very good price. Now I ask myself, if I could control the XL via Midi using the B's control knobs. The XL, as it is, would be a bit complicated to control just by its knobs, and I don't use a computer very often to make music. Don't like to stare at a screen while beeing in a creative process.
Since the functions in B and C are similar (not exactly the same, I know), there should be a way to connect them and to remote the XL, which is basicly a C. Are the CC-numbers the same in both units?

Thanks for answering
