If you are talking about using the LEARN function on the BC2000, then even if the DW would output parameter sysex it is of limited use except for the buttons on the BC2000.
The BC2000 can be much more extensively programmed with an PC editor and you can have the knobs and buttons working the DW in real time (even the sliders if you have a BCF2000).
A lot of this work has already been done for you and it is available for free on the Yahoo BC2000 group.
