I think the MIDI command just has to arrive later, but this is a slightly obscure feature, so actual synthesizers might do something else. However, this is probably irrelevant, because synthesizers recognize overlap only if legato/portamento mode is on — and it usually isn't on by default, because it misinterprets chords. So the slurry sound of overlapping notes is just due to overlapping sound, not to special synthesizer support. Maybe Lilypond could emit the command to turn on portamento mode when there are no chords; I haven't tried this. Slur overlap doesn't improve the sound nearly as much as articulations, and breaks midi roundtripping, and the current implementation is ad-hoc, so maybe it shouldn't be included. How does the parser create slurs? They seem to be post-events, but I don't see where they're defined. It would be more flexible to do slurs with a perform-length property on the SlurEvent, and that would generalize to other spanners. _______________________________________________ lilypond-devel mailing list [email protected] https://lists.gnu.org/mailman/listinfo/lilypond-devel
