This video shows how to get the chords from Biab Plugin into Reaper. The chord sheet has to be unfolded in the Biab Plugin so it is a linear progression. It is then saved and loaded again.
The first time run will ask for the Band in a Box application folder location eg. C:\bb

right click Save Link/Target As
ReaTrak import chords from biab plugin.lua

Reaper > Actions > Show action list > ReaScript > Load > ReaTrak import chords from biab plugin.lua
after it has been unfolded, Saved and reloaded
Run > ReaTrak import chords from biab plugin.lua

File > Project settings > Project start measure > -1
