Gregofacsimil + neumes from H + rsigns according to H. Verse structure according to the mss that have it (a couple of german and polish ones, but none of the usual franciscan ones). The verse structure differs from Solesmes scores for this piece. Added a si flat to Gregofacsimil on VALde for disambiguation.
The bizarre ending of this R/, and the nature of the Si there, should be discussed with dcrochu - done - it is what it is; the flat si is prepared on the previous syllable, this was a mistake in GFS.
LRT corrections by dcrochu.
