Yes, it should take nothing more than that - just set chord markers to ON. As mentioned, I’ve run Scaler in two different hosts and dragged chords from Scaler to my hex reader. Also, I did a fresh portable install of Reaper, and uninstalled/reinstalled Scaler. Still not happening 
What does it suggest if dragging from Scaler to a hex reader shows it’s a file without the chord name?
Thanks for checking.
