Hello again, LlilyPonders. I think I have discovered an unreported bug in both 2.24.4 and 2.25.26, but I'd like to run it past y'all first.
If you set tieWaitForNote, the inner ties cannot be changed with the \shape command. The outer tie works as expected. Here's a MWE: %%% % \version "2.25.26" % same effects as 2.24.4 \version "2.24.4" tieShape = \shape #'((0 . -1) (0 . -1) (0 . -1) (0 . -1)) \etc \relative { \set tieWaitForNote = ##t d''4~ c~ b~ <d c b> | % ties without shaping d4-\tieShape ~ c~ b~ <d c b> | % outer tie affected by shape d4~ c-\tieShape ~ b~ <d c b> | % both inner ties are not affected d4~ c~ b-\tieShape ~ <d c b> | } %%% -- Knute Snortum
