Between Phil's suggestion, which prompted me to add a missing: \context { \PianoStaff \consists #Span_stem_engraver }
in the layout {} block (which made cross-staff beaming possible), and Thomas’ suggestion to use \tweak #'duration-log #, I've got this working nicely. The hardest thing was that I had never used #'duration-log and did not know that the numeric values don't match the note-lengths used elsewhere. Took a bit of trial and error, but it worked in the end. Thank you all very much. Now I'm back in business :-) Best, Arle _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
