This is just an RT RC piano in Reaper, it will do the same in Biab, duplicate the notes to where you need and they will become PRT notes that will play along with the audio. If I mute all notes except for the new ones I have added then load the RT piano sfz it will play that chord when playing back the audio track with the Sforzando midi track:
