Parameters can go from anything to anything, BUT Midi data can only go
from 0 to 127 (00 to 7F)

The BCR uses 14bit numbers internally 0 to 16383 ($0000 $3FFF) but the
Midi CC message has the Status byte B0 to BF then 2 data bytes.
Controller number 0 to 128
Controller value 0 to 128
So nothing can transmit CC value of 164, including Dave Smith
He would have to split the value into at least 2 data bytes.
He could do this with 2 controllers (Like the way a preset bank is
selected with CC0 and CC32)
He could do this with sysex, which is the way most folk do it.
Pitchbend has 2 data bytes so he, in theory, could do this but unlikely.
It is likely that you can map a incoming CC to the filter and although
you wouldn't get the fine resolution you would get the range.

See the document Secrets.pdf in the files section I think I went
though multiple data bytes in that.

The BCF/BCR can do any of these messages (including multiple message
on the one control.)
The only cases where it gets stuck is when the data is packed (the Osc
octave and the Osc wave type are in the one byte as in the DW6000)
This was used when memory was expensive, so in your case I'm sure it's
not an issue.
Negative numbers where 2 bytes are used for the data as in the EMU
Morpheus/Proteus etc -7 to 7 but I need $7F $79 to $00 $07
You will need to check the Midi spec to see if this is a problem
The BC can happily do -7 to 7 with a single byte of data $79 to $07
It can do most things as far as controlling a hardware synth.
How would you go about it? There is heaps of messages from other
people that have written presets for hardware synths. Check them out.
Grab Mark's brilliant editor and BCL (Behringer Control Language)
document on his website.
Give it a shot and then ask folk here for some help if you need it.
I hope this helps
