\longa and \maxima

[Urs Liska]

Hi all,

do we have something for the notehead in the attached image?

I need to print a note lasting four 4/4 measures.

{
  c'' \longa
}

does produce the desired duration and the result shown in the second attachment. But is it possible to have a \maxima notehead or does this not exist in Emmentaler?
\maxima seems to be reserved for rests since

{
  c'' \longa
}

yields

none of note heads `noteheads.s' or `noteheads.d' found

Is this a missing notehead in Emmentaler, or do we not have such a glyph on purpose? And do I have an option other than hand-drawing what I need?

Thanks
Urs
