Melody from Fco2 f. 217v https://www.e-codices.unifr.ch/en/fcc/0002/217v corrected by formulaic coherence with 0908I (and the rest of the Matian series) and 0722I (and the rest of the Laudemus series)

Rectification of the height of the first pressus to favor the French tradition (re-re-do in https://gallica.bnf.fr/ark:/12148/btv1b84262784/f231.item.zoom and other FR manuscripts, instead of mi-mi-re in Fco2 and germanic manuscripts)
