Music Help for Preces in Liturgica Horarum

I would be much obliged if any of our readers can direct me to a book or publication that gives the music for singing the Latin "preces" in the Liturgia Horarum. I believe that there are melodies for singing the "General Intercessions" in Latin in the Missale Romanum. What I am trying to find is whether any particular music was ever provided for the Preces.

Thanks for your kindness and patience.
