This measure is not encoded the same as in the original (page 16 of http://ks4.imslp.net/files/imglnks/usimg/8/86/IMSLP14741-Debussy_-_5_Po%C3%A8mes_de_Baudelaire_(voice_and_piano).pdf)

Although there would still be a problem:

The problem is in verovio, where a clef cannot split a note (the low C in this case), so the clef is pushed until after the note.

Related to issue https://github.com/rism-ch/verovio/issues/935

The solution will be to use this clef for the whole-measure (or dotted half note) layer:

      <clef sameas="clef-L9F1" />

This will produce the notation:

T214_Sch-w33p28-29m124-129 has a similar situation, where the clef splits implicit rests in the second layer:

There is a problem with the tuplets, which should be labeled "2" rather than "4". But for this particular example, the 9/8 for the voice part is probably due to a limitation or complication in sibelius for dealing with polymetric music, since the voice is in 3/4 and the piano is in 9/8 at this point in the score:

Original music for this example:

@epoudrier can comment about whether or not the voice part in the polyrhythm website rendering should be in 3/4 eventually (notated as normal 8th notes in 3/4 as opposed to duplet eight notes in 9/8).

I do think that eventually, we would like to have all the time signatures represented. I would be in favour of editing in Humdrum and adding an editorial note to the Sibelius rendering for future users.

This is easy to do in Humdrum, although I will wait to do a manual correct. Perhaps I should create a spreadsheet for manual corrections (for implementing after automatic corrections have settled down). This may be related to the error list in the sibelius PDF files that you had someone do at Yale, so we could start with that list. I would most like be the person to add to the list as I sort through the reports in the polyrhythm repository issues (deciding if they are automatic errors or errors in Sibelius/MusicXML that need to be corrected in Sibelius and/or Humdrum).

[craigsapp]

Well maybe not that easy (I tried to do it, but there are problems with the tuplets I probably have to fix).

ex. T672, Hindemith, cello, bar 1, there should be a bass clef instead of a "repeated" tenor clef. It happens as well for both hands of the piano.
