Bc2000 (for the BCF2000 & BCR2000)

I have an RME Fireface UC, which provides a HUI interface for remote control.  I would like to use a BCR2000 to control the Fireface.  I found the BCR2MCU.syx and sent it to patch 15 using Behringer's bcedit.jar Java program.  I then enabled MIDI control on the RME TotalMix FX software and set MIDI In under Settings to BCR2000.  The result was that the lower right knob now controls the master volume on the RME TotalMix console.

How can I use the BCR2000 to affect the rest of the RME TotalMix controls?

Thanks,

Mike
