Here: Assigning MIDI CC for BCF2000 - #2 by Martin.Jirsak
If all you need to do is send CCs to Cubase for vol, mod, exp etc., , just plug it in and set the midi track to receive from and send to the BCF.
Add a Midi Monitor insert to the track to learn what the device is sending.
The information on how to set up the BCF is in the manual for the device, and not specific to Cubase.
