Slurs with 2 curves, and ornaments
I am trying to notate an unmeasured prelude (harpsichord) of Louis Couperin, see attached pdf for the L'oiseau Lyre edition. The unmeasured notes can be done, but I am stuck with the slurs which do not go only in one direction, but are very elegant in two directions (see last bass-notes in first system). Is there some solution for this?
Also I cannot find the correct ornaments, see second note in second system, but especially the two cross-like ornaments further in the second system. I have checked the master palette, but I did not find them. Is there a way to add them myself?
