Bc2000 (for the BCF2000 & BCR2000)

The BC OS can be updated by sysex.
On a quick initial inspection these short sysex messages look to be of
the form
Header + 2 (possibly 3) flash address + OS data + $F7
If this is the case the OS data is scrambled (not in order) and so
will have to extracted into a block of memory to reorder it inside the
PC line by line then disassembled.

As the OS data is either 8 or 16 bit, 7 bit Midi will have to be
converted. I'm not sure what conversion is used.

The flash seems to be divided into 3 sections. My guess is a boot
loader, the main program and program data. 

There is this message about $200 bytes in
'be in control with the b-control by BEHRINGER hw/sw by Thomas Zint'

So thanks Thomas, my BCR2000 is great.
