I wonder if there is an edit buffer request for the Pro-800? I also wonder if Behringer has a Sysex implementation to download? According to Behringer there is both CC and NRPN control of all parameters but no information about sysex
MIDI system exclusive data is 7 bits (00-7F), but Pro 800 data uses 8-bit bytes. These bytes are encoded as follows. Each sequence of seven bytes x1 x2 x3 x4 x5 x6 x7 is preceeded by a byte x0 that specifies the MSBs of the following seven bytes. The MSB of x0 specifies the MSB of x7; the LSB of x0 specifies the MSB of x1, and so on.
