Yes! Both BIAB and Scaler add midi markers to the output midi file which contain the chord name they have assigned (i have no idea how they do this, but they do). Reaper knows how to insert these midi markers into its own "project markers" when the midi is inputted. The markers serve only as text labels on top of each bar.
