That Denemo plays back as the music is exported, e.g., to lilypond? I had expected Denemo to play back as shown in the editor, not taking into account directives that might skip or fill anything for the print output. Moreover, as Joe showed, the playback can also be brought out of sync by incomplete measures. This may not be what an average user expects, but is in accordance to how such music is shown in the print output. That behaviour can also be handy, e.g. for ancient music where notes may extend into the next "measure", resulting in an overfull and a following underfull measure in the Denemo editor, but a correctly typeset score in the print and a correctly sounding playback. The question is: Which behaviour is best for the majority of use cases? Andreas ___ Denemo-devel mailing list Denemo-devel@gnu.org https://lists.gnu.org/mailman/listinfo/denemo-devel

The problem is that the first measure is not empty - it contains the repeat start directive, so it is *not* filled with a space, as Denemo does not know what that directive is doing. Empty measures must be truly empty if you want Denemo to tacitly insert a whole measure rest. If you put a whole measure rest in the first measure, all is well.

Re: [Denemo-devel] Playback asynchronous
This file will do it.
I created top line, then bottom, then middle.
With whole bars empty it played normally. Then deleted a minim in middle
staff, bar 2.
Middle staff now plays back async with rest.

Working on a score in which some measures are still without notes, I
encounter an asynchronous playback, i.e. during playback some staffs lag
one measure behind the others. This is illustrated in the attached
screenshot. Notes from one measure sound together with notes from the
next measure from other staffs, which is not so good for checking it.
Has anyone else encountered this problem? I could not reproduce it with
very simple scores with two staffs.
@Richard: I can send you the score by pm for debugging purposes.
