Hello,
I'm still fighting against the problem of setting a vertical gap between
two pedal spanners. Or, in general, between two spanners.
I find *very* strange there's not such a feature in Lilypond, which is IMHO
very important and it currently can be implemented only (in a uncomfortable
way) with a redundant Dynamics layer. Or by modifying the \sustainOn
function in a way that it has to be placed before a note (which can cause
messy syntax).
The only hack I could implement, that preserves Lilypond's syntax, is the
following code:
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% LilyBin
#(define addGap #f)
#(define currPed "")
#(define pedid 0)
{
\set Staff.pedalSustainStyle = #'mixed
\override Staff.SustainPedal.before-line-breaking = #(lambda (grob)
(if (eq? addGap #t)
(begin
(set! addGap #f)
(if (not (string=? currPed "sustain"))
(ly:grob-set-property! grob 'stencil
(grob-interpret-markup grob #{ \markup \concat { \medium
\fontsize #-2 "Ped." \draw-line #'(0 . 4) } #} ))))
(begin
(set! addGap #t)
(ly:grob-set-property! grob 'stencil
(grob-interpret-markup grob #{ \markup { \medium \fontsize #-2
"Ped." } #} ))
(set! currPed "sustain"))))
\override Staff.SostenutoPedal.before-line-breaking = #(lambda (grob)
(if (eq? addGap #t)
(begin
(set! addGap #f)
(if (not (string=? currPed "sostenuto"))
(ly:grob-set-property! grob 'stencil
(grob-interpret-markup grob #{ \markup \concat { \medium
\fontsize #-2 "S.Ped." \draw-line #'(0 . 4) } #} ))))
(begin
(set! addGap #t)
(ly:grob-set-property! grob 'stencil
(grob-interpret-markup grob #{ \markup { \medium \fontsize #-2
"S.Ped." } #} ))
(set! currPed "sostenuto"))))
c'4\sustainOn c' c'\sostenutoOn c'\sustainOff\sostenutoOff r1\break
c'4\sostenutoOn c' c'\sustainOn c'\sustainOff\sostenutoOff r1\break
%WRONG
c'4\sostenutoOn c'\sostenutoOff c'\sustainOn c'\sustainOff r1\break
}

Unfortunately, it doesn't work on the last system: as you can see, an
erroneous gap is added on the last pedal.
It could work if we find a way to check if the pedal belongs to a
VerticalAxisGroup which has two pedals. In this case, a gap can be added to
the second pedal.
Any help is greatly appreciated!
Best,
P
