This is from another post:

Well there are 2 ways you can do it
1. wait for PG to get around to to adding chord markers to the BB Chord Output track (that's been asked for ages) in BBW4 and enable it to take the function call from the Plugin.
2. Create it all in the Plugin as suggested in the first post, or you could have a Chords.txt that the Plugin uses to create the midi chords, this way the user can set any voicing they like for any chords. So it will be all done in the Plugin without waiting for PG to do it.

This is an example from Ackord Midi Chord Detector, being in notes than numbers it's more user friendly.
Code:
; This is the chord definition file.
; Here you make up which key combinations make up which chord.
; Do it for key C, and the program will automatically transpose 
; it to all other keys. 
; If a / (division sign) is after the note name, that means it is okay to
; have this note in the base - e g C/G. If not, it will be an 
; unrecognized chord - unless another row later has this combination.

; Every line not beginning with "C" will be ignored by the program.
; Separate notes with , (comma). No spaces between notes. 
; Valid notenames: C, C#, Db, D, D#, Eb, E, F, F#, Gb, G, G#, Ab, A, A#, Bb, B
