Re: grace-note spacing and triplets

[Jan-Peter Voigt]

Hi Simon,

thank you for your snippet! In my case, I will use the extra-offset 
variant, but I'll take yours for future use :-)

As there is a whole orchestra between flute and voice, I use this as 
acceptable tweak:

  \once \override NoteHead.extra-offset = #'(-1.5 . 0)
  \once \override Stem.extra-offset = #'(-1.5 . 0)
  \once \override Flag.extra-offset = #'(-1.5 . 0)
  \once \shape #'((-1.5 . 0) (-1.1 . -0.3) (-.7 . -0.3) (-0.3 . 0)) Slur

If one is interested, I attached a file, where I use the 
edition-engraver to apply this tweak.

Cheers
Jan-Peter
