Maybe:
\version "2.19.15"
printTimeSignatureFraction =
\applyContext #(lambda (ctx)
(let* ((context
(ly:context-property-where-defined ctx 'timeSignatureFraction))
(time-sig-frac
(ly:context-property context 'timeSignatureFraction)))
(display time-sig-frac)))
\relative c' {
\time 3/2
\printTimeSignatureFraction % => (3 . 2)
c''1
\compoundMeter #'((1 4) (3 8))
\printTimeSignatureFraction % => (5 . 8) !!
\repeat unfold 5 c8 \repeat unfold 10 c16
}
Though the compound TimeSig will return "summarized"
Cheers,
Harm
