This document contains all the details of the BCF2000 and BCR2000's MIDI implementation.
However, it goes way beyond what you normally expect from a MIDI implementation document: there are explanations of all global and preset parameters, tables and descriptions of special functions, etc. It also provides a nearly complete description of BCL, Behringer's MIDI-embedded language that controls the BCF/BCR2000.
Basically this document is a must for every BCF/BCR2000 owner. It is also an indispensible companion to the BC Manager program, in particular if you're going to write 'custom' button/encoder/fader definitions.
Note: This file is also included in the BC Manager package, so if you download BC Manager, you don't need to download this file separately.
