But with (let ((l-f (ly:grob-property grob 'length-fraction)))) I got '() eyery time.

Try: \relative c' { \stemUp \override Beam #'stencil = #stencil-plus-bracket f32 [f'] } Anyway, I will post my function once work is finished. I can see the end. And if other problems with it are appearing, I start a new thread hoping you can answer my questions again.;) Thanks a lot, Harm -- View this message in context: http://old.nabble.com/How-to-read-out-the-number-of-beams-and-the-space-between-them--tp32662208p32671061.html Sent from the Gnu - Lilypond - User mailing list archive at Nabble.com. _______________________________________________ lilypond-user mailing list [email protected] https://lists.gnu.org/mailman/listinfo/lilypond-user
