Since I got no further reply on this suggestion, here is the respective
code that should work as expected.
\layout {
\context {
\type "Engraver_group"
\consists "Time_signature_engraver"
\consists "Axis_group_engraver"
\name "TimeSig"
\alias "Staff"
\override TimeSignature #'font-size = #3
\override TimeSignature #'break-align-symbol = ##f
\override TimeSignature #'X-offset =
#ly:self-alignment-interface::x-aligned-on-self
\override TimeSignature #'self-alignment-X = #CENTER
\override TimeSignature #'after-line-breaking =
#shift-right-at-line-begin
}
\context {
\Score
\accepts TimeSig
}
\context {
\Staff
\remove "Time_signature_engraver"
}
}
timeSignatures = { \numericTimeSignature \time 2/4 s2 \time 3/4 s2. \time 4/4
s1 }
\score {
<<
\new TimeSig \timeSignatures
\new Staff \relative { c'2 c2. c1 }
\new Staff { a2 a2. a1 }
>>
}
