Bc2000 (for the BCF2000 & BCR2000)

Hi People.

I have Propellerheads Reason V4, Midi USB linked via my laptop to an M-
Audio Oxygen V2 Midi KB and then USB linked to my BCR2000.  Well, I say 
Midi linked, the Oxygen works ok with Reason via the USB link but the 
BCR I am having problems with.
Is there a way of using the Oxygen to play notes and to use the 
rotary's on it to alter parameters (buttons) plus also using the BCR to 
alter parameters (buttons)?
I have a Midiman USB Midisport 2x2 Midi interface and several link 
leads if that needs to be used at all???
Also, how do you program the rotary buttons on the Oxygen (or the BCR) 
to actually move the buttons on the Reason program?

I am new to all this and probably am not exactly putting this across 
very well but any help will be appreciated.

Thanks
Jim
