Hi Paolo,

Here’s an edited version, using your method:

%%%%
\version "2.19.83"

notesA = { c''4 4 4 4 }
notesB = { a4 4 4 4 }
dynsAndPedPattern = { s4\sustainOn s s s\sustainOff }

% GOOD
{
\partcombine
{ \notesA } { \dynsAndPedPattern }
\partcombine
{ \notesB } { \dynsAndPedPattern }
\partcombine
{ \notesA } { \dynsAndPedPattern }
}
%%%%

To my eye — as engraver and pianist — it looks terrible.
But maybe you like it?

Hi Kieren,

your version does *not* correspond to my above example.

Please look again at it. I inserted stuff between pedals, so to make them enough distant.

In order to align pedals at right and left, you could use a combination of after and before-linebreaking.

Look at this example (again: messy code that could be improved, and I gently ask Harm and/or Aaron to have a check if they can):

%%%%

#(define pedalOffs 0)
alignPedsAfterRef = \override Staff.SustainPedalLineSpanner.before-line-breaking = #(lambda (grob)
(ly:grob-set-property! grob 'Y-offset pedalOffs))
stopKeepingPedalAligned = \revert Staff.SustainPedalLineSpanner.before-line-breaking

alignPedsBeforeRef = \override Staff.SustainPedalLineSpanner.after-line-breaking = #(lambda (grob)
(ly:grob-set-property! grob 'Y-offset pedalOffs))

setAlignRefPed = { \override Staff.SustainPedalLineSpanner.after-line-breaking = #(lambda (grob)
(set! pedalOffs (ly:grob-property grob 'Y-offset)))
\override Staff.SustainPedalLineSpanner.before-line-breaking = #(lambda (grob)
(set! pedalOffs (ly:grob-property grob 'Y-offset))) }

notesA = { c''4 4 4 4 \noBreak }
notesB = { c'4 4 4 4 \noBreak }
notesC = { f4 4 4 4 \noBreak }
dynsAndPedPattern = { s4\sustainOn s s s\sustainOff }

{

%%%% ALIGN PEDALS ON THE NEXT MEASURE
\alignPedsBeforeRef
\partcombine
{ \notesA } { \dynsAndPedPattern }

\setAlignRefPed
\partcombine
{ \notesB } { \dynsAndPedPattern }

%%%% ENOUGH DISTANCE HERE, STOP ALIGNING, SO TO AVOID HOLES
r1 r r r

%%%% ALIGN PEDALS ON THE NEXT MEASURE
