Source, with LH83 rsigns. The only difference with the GFS invitatoriale is on "praeoccup_e_mus", GFS has SI. More melodic, but the Gloria Patri also does not have SI so Solesmes' version is still coherent (other verses have it in Solesmes and GFS)

Another melodic difference with GFS : to~ instead of pe~ on "et _in_ psalmis" and corresponding syllables in all other verses.

Added pressus typography in (Veni)_te_, because mss have it: cf. https://www.e-codices.unifr.ch/en/csg/0388/6 et al
