I thought about this recently for both dynamic and pedal marks. I thought 4
tracks (RH, LH, dynamics, pedal) on one channel would distribute all the
changes. Either my midi knowledge is wrong or/and that couldn't work well
about how a mark would be handled if it applied to only one line. I don't
want to start hate mail and fired discussions, but better notational & midi
knowledge is something I can always use so . . .
Thanks again,

It's probably the easiest to make a Piano_pedal_swallow_performer that
sits at the piano-staff level, and have that scoop up the events. Then
have Piano_pedal_performers at staff level. This is similar to
Repeat_engraver which cooperates with the Repeat_acknowledge_engraver.
Let me know if you have more questions!

Re: Piano Pedal performace across a PianoStaff
Interesting, you get a SIGSEGV!
However, if you replace "Piano_pedal_performer" with
"Piano_pedal_engraver", LilyPond will process the file without
crashing. Still, it doesn't do what you want.
The next time, you try these things, remember that "_performer":s
deal with MIDI file creation, whereas "_engraver":s deal with
paper typesetting. To see the default definition of the contexts,
take a look at the file ly/engraver-init.ly.
Here's a full example file for those who want to try it out more.
\version "2.2.0"
upper = \notes\relative c'' {
c4 d e \sustainDown b |
c c, \sustainUp \sustainDown d8[ c] e8[ e \sustainUp \sustainDown] |
}
lower = \notes\relative c {
c1
d1
f4 d \sustainUp g \sustainDown b |
b, \sustainUp c'
}
\score {
\context PianoStaff <<
\set PianoStaff.instrument = "Piano " % set instrument name.
\context Staff = upper \upper
\context Staff = lower <<
\clef bass
\lower
>>
>>
\paper {
\context {
\VoiceContext
\remove "Piano_pedal_engraver"
}
\context {
\PianoStaffContext
\consists "Piano_pedal_engraver"
}
}
\midi { }
}

but I can see that I was wrong. What would be necessary to make
something like this work? I am willing to code it, but I would
appreciate a push in the right direction.

Piano Pedal performace across a PianoStaff
A pedal-event is currently performed by the staff context within
which it is declared. As a piano's pedal tends to affect the entire
output of the piano and not just one hand, it would be nice if
pedal-events could be automatically performed across the staves in a
PianoStaff. My instinct was to use the following:
\context {
\VoiceContext
\remove "Piano_pedal_performer"
}
\context {
\PianoStaffContext
\consists "Piano_pedal_performer"
}
but I can see that I was wrong. What would be necessary to make
something like this work? I am willing to code it, but I would
appreciate a push in the right direction.
