Here is the common part, along with descriptions of each byte’s purpose:

F0 - Start of Sysex [SOX]

00

00

1B - Peavey Manufacturer ID = 00 00 1B

11- BAM Product ID (10 for PFC4B commands: CMD = 00, 01)

00- Reserved for future use (keep fixed at zero)

CMD - Command byte that defines which Sysex message it is

<data>

- Optional data

F7

- End of Sysex [EOX]

NOTE: Each time a preset is recalled, it is first loaded into a RAM buffer that we call the Edit Buffer (could also be called “current preset”). If another preset is recalled, the Edit Buffer is erased, so any changes will be lost unless stored to a User location (or externally). In the table below, we refer to this preset location as the “EdBuf.”

Now for the unique stuff:

*Nibblized data is sent hi nibble, then low nibble. E.g. a hex byte value of 74 will be sent as two bytes: 07 and 04. This is because MIDI data bytes really only have 7 bits - the most significant is reserved to be set for status bytes only.
