Dear All,
I've tinkered about some more with partial pedalling and gradual sustain pedal release, and here's some code (some of it copied/adapted from the internet) that seems to work, even though in some respects it shouldn't: \version "2.20.0" \relative c'' { \set Staff.pedalSustainStyle = #'bracket % 1. standard sustain pedal behaviour c1\sustainOn c \sustainOff \sustainOn c\sustainOff c % 2. gradual pedal release indicated by dashed line \once \override Staff.PianoPedalBracket.edge-height = #' (1 . 0) c1\sustainOn \once \override Staff.PianoPedalBracket.bracket-flare = #'(0 . 14.5) \once \override Staff.PianoPedalBracket.edge-height = #' (0 . 1) \once \override Staff.PianoPedalBracket.style = #'dashed-line c \sustainOff \sustainOn c c4\sustainOn \sustainOff c c c % 3. 1/2 pedal instruction \set Staff.pedalSustainStyle = #'mixed \once \override Staff.PianoPedalBracket.edge-height = #' (0 . 1) \override Staff.PianoPedalBracket.bracket-flare = #'(8 . 0) \once \override Staff.SustainPedal #'stencil = #(lambda (grob) (grob-interpret-markup grob (markup "½"))) c1\sustainOn c c \sustainOff } In the second snippet, the slanted pedal release line ONLY works if \sustainOff in the final line is preceded by \sustainOn; otherwise the line remains horizontal. It doesn't make complete sense to me, since there's already a \sustainOn in the preceding line. So this is probably isn't how it's supposed to be done, but for now it offers a simple way of notating gradual sustain pedal release. Jan
