Hello.
Please consider this (tested on 2.19.84):
\new Voice <<
{ \shape #'((0 . 0) (0 . 0) (0 . 0) (3 . 0)) Tie c' ~ c' }
{ \shape #'((0 . 0) (0 . 0) (0 . 0) (0 . 0)) Tie c'' ~ c'' }
>>
If I modify the shape on the first tie, changes are applied on the second tie. Is this a bug? If so, is there a fix/workaround for this?
I tried \partcombine too, and the issue persists.
Thanks.
Best,
P
