David, a.k.a. Augnus_Dei has been posting some recordings of this instrument on CCH. A very interesting instrument indeed! I wouldn't classify it as your first choice in go to 'church music' repertoire instruments, but none the less great for certain types of music and would be a good one to have in one's lineup depending on what you're either into playing and / or what you feel like playing on a given day. The sound is impressive and very clear as is the other recent offerings from Lavender, and the acoustic is really nice. With the stops it has to offer and the kinda sorta meantone sounding tuning, it actually does a nice job of mimicking a classical French baroque instrument rather accurately if you like for certain pieces. Call it a new / old French baroque sound?
