Here is a second mass from the same manuscript. It was a problem with the Gloria : there was no "Grand Jeux" to close the piece. I found in the score a nice piece in the same tonality (G minor) for "basse & dessus de trompette" and had just to change the registration to play it as a real "Dialogue" and it works well.
Because this music was played certainly on a medium size organ, I decided to record this mass using the Zamardi sample set produced by AVO, a nice french baroque copy.
