I have a score where the sustain starts in the voice in the bass clef, and
ends after the voice crosses into the treble clef. It compiles but with a
warning: cannot find start of piano pedal: `Sustain', with respect to the
sustainOff. The warning goes away if I comment out midi{}. However it would
be nice to understand what is giving rise to the problem. I tried keeping
the sustainOff in the bass clef, despite the voice crossing, but this did not
help.
Here is the measure in question:
\version "2.20.0"
upper = \relative c'' {
\clef treble
r2. \hideStaffSwitch\change Staff = "lower" r4*1/2 s8 \sustainOff |
}
lower = \relative c {
\clef bass
b8 ees, aes c, b \sustainOn ees' \showStaffSwitch\change Staff = "upper"
aes ees' |
}
\score {
\new PianoStaff <<
\new Staff = "upper" \upper
\new Staff = "lower" \lower
>>
\midi { }
}
