Hi Trevor,

I stumbled across you're printing a rest-glyph for a quarter-note.

Eventually I might have some ideas, but there are a plethora of
variants for historic tablaures. Which glyphs do you want to be
printed above the TabStaff for the code below. Only flags, flags with
stems, stems only for quarters, what to do for notes longer than a
quarter?

m = { \compressFullBarRests c'\maxima \longa \breve 1 2 4 8 16 32 }

<<
  \new MensuralVoice \m
  \new TabStaff \with { \revert TextScript.stencil }
  \new TabVoice
    \with {
      \consists \Lute_tab_duration_engraver
    } \m

Cheers,
  Harm
