Yes, I do. The solution you had suggested (redefining the ChoirStaff
context) had already occurred to me...

Thanks, your comments gave me the hints I needed, as demonstrated below.

I indeed have looked into this file (and the related ly/performer-init.ly),
although, as you mentioned, "the default definition of ChoirStaff is a bit
complicated".
In the end, I came up with the following, which seems to work for me:
\layout {
\context {
\GrandStaff
\name "BraceStaff"
\type "Engraver_group"
\alias "ChoirStaff"
\remove "Span_bar_engraver"
\remove "Span_arpeggio_engraver"
\accepts "Staff"
\accepts "FiguredBass"
\accepts "TabStaff"
\accepts "Lyrics"
\accepts "ChordNames"
\description
"Just like @code{ChoirStaff} but with a brace
(@code{SystemStartBrace}) instead of a bracket
(@code{SystemStartBracket}) at the start of each system."
}
\context {
\Score
\accepts "BraceStaff"
}
}
\midi {
\context {
\GrandStaff
\name "BraceStaff"
\type "Performer_group"
\alias "ChoirStaff"
}
\context {
\Score
\accepts "BraceStaff"
}
}
Once again, thank you for all your help!
Yours truly,
John Zaitseff
