Thank you. I forgot about Moroney. He completed his cycle in 2018 - four sets of three CDs each.
Mark Kroll's cycle may be as complete as it will get. He hasn't done "L'art de toucher le clavecin" but all of books 1-4 have been released. And his CD covers say "Complete Pièces de Clavecin", not complete harpsichord works.
