Re: Simultaneous Key Changes

[Will Oram]

Apologies for the delay -- my primary mail address was causing  
lilypond-user to repeatedly unsign me.

I don't know what went wrong with the snippet below. This I have run  
just now on .25 and works fine AND demonstrates a) the simultaneous  
key change quirk, and b) the odd triplet bracket. I would expect a  
bracket spanning three notes, but it spans 7+ measures instead.

\version "2.9.24"
\include "english.ly"

Top = {
        \clef "bass"
        \key c \minor
        \time 2/2
        
        c1
        R1
        
        R1*2
        
        aflat2 r
        r2 \times 2/3 { g,8-.[ b-. d-.] } \times 2/3 { g-.[ b-. d-.] }
        eflat1
        eflat2 d4( c)
        bflat!2 r
        R1
        eflat,2. g4
        bflat r r2
	\times 2/3 { c,8-.[ eflat-. g-.] } \times 2/3 { c-.[ eflat-. g-.] }  
a4 r
        b,2( c4 bflat)
        aflat1~
        aflat2 g4 r
        
        R1*3
}

Bottom = {
        \clef "bass"
        \key c \minor
        \time 2/2
        
        c1
        R1
        
        R1*2
        
        c2 r
        R1
        eflat1
        eflat'2 d4( c)
        bflat!2 r
        
        R1*4
        
        b2( c4 bflat)
        aflat1~
        aflat2 g4 r
        
        R1*3
}

\score {
        \simultaneous {
                \new Staff <<
                        \partcombine
                                \relative c' { \Top }
                                \relative c { \Bottom }
                >>
        }       
        
        \layout {}
}
