I have asked for this so many times over the many years.
Make sure you have the # Ticks before chord change to 0

If you had BB21 you simply open the SGU in the Biab Lite Standalone and drag the chord midi markers out.

If you have an older version of Biab you can drop the BB Chord Output midi file into Reaper and it will write the midi chord makers in the file so the others in the group can read the chords in their DAW.

You can also save as musicxml and drop that in Reaper and it will create midi chord markers.

Another way is save to youtube video and convert to mp4 video and send that to them as most DAWs will have a video track.
