Hi Xavier,

do you think of sth like this:

\version "2.17.12"

boundPadding =
\override MultiMeasureRest #'before-line-breaking =
  #(lambda (grob)
    (let* ((measure-count (ly:grob-property grob 'measure-count))
           (b-p (if (> measure-count 1)
                      20        ;; bound-padding for single MMR
                      15)))     ;; bound-padding for compressed MMR
   (ly:grob-set-property! grob 'bound-padding b-p)))

{
        \boundPadding
        R1
        \repeat unfold 20 { c'' }
}

{
        \boundPadding
        \compressFullBarRests
        R1*5
        \repeat unfold 20 { c'' }
}

Cheers,
