• markup for instrument name: \instr

• bug: figures for a note without duration after a full bar rest

  // Change the footnote number/sign, string escaping cd [*:"Is this "note" connected to the one before?"] e

  // footnote references, and footnotes at end of doc (or apart from music) cd [^] e ... // some markup ["Is this place free?"]
