Bc2000 (for the BCF2000 & BCR2000)

Hi all, 
i am trying to use the "encoder group" buttons as MIDI buttons... but 
i dont know how to do it directly from my BCR2000. 
i know u can make it using the B-CONTROL EDIT, but it doesnt work in 
my pc... i can load things from the BCR200, but i cant save them to 
the BCR2000. (btw... there isnt any B-CONTROL EDIT for mac os x, 
right ?) 

any help on how to do this will be much apreciated
