hello Orm, Trevor...
Sorry I have not been helping here. I had not checked my lilypond mail
for weeks! Thankfully we have Trevor, the sponsor of proportional
notation!
So, coincidentally, I just finished a piece for flute where I do
*exactly* the same thing Orm is trying to do: align a lilypond score
with some other graph above. My alignment came out almost perfect. There
are a couple of places where the score is just slightly off and I'm not
sure why this is, but you can barely notice it.
Trevor has pointed out the main elements to adjust for strict
proportional notation:
1. \set proportionalNotationDuration = #(ly:make-moment n d) (in the
Score)
2. \override SpacingSpanner #'uniform-stretching = ##t (in the Score)
3. \override PaperColumn #'used = ##t (in the Score)
4. \remove Separating_line_group_engraver (in the Staff)
5. \override SpacingSpanner #'strict-note-spacing = ##t (in the Score)
Out of these I only used no. 1,2 and 5.
Staffs in my score do have Separating_line_group_engraver, and I didn't
know about PaperColumn.
So are these two strictly necessary? In what cases would they be? Could
removing Separating_line_group_engraver have unwanted secondary
consequences... this creates the StaffSpacing grob correct?
Not sure I understand what PaperColumn #'used does...
I will try applying numbers 3 and 4 to my score and see what happens.
(and will be checking my email more often :| )
Trevor, I'm happy to help put together a tutorial on proportional
notation and temporal spacing issues in general.
Victor.
