Hi Jaime,

I'll look into lengthening it to reach the stem.

Not at all easy, I'm afraid.  Are you looking for the cluster-band sort of notation, or would individual clusters per stem suffice (like Cowell, for example)?  Possibly the latter would be easier to implement.

Here's a simple test.  (A rounded box might be preferable.)

 \version "2.19.15"

{

  \hide NoteHead

  \override NoteColumn.stencil =

  #(lambda (grob)

     (let* ((noteheads (ly:grob-object grob 'note-heads))

            (ext-X (ly:relative-group-extent noteheads grob X))

            (ext-Y (ly:relative-group-extent noteheads grob Y)))

     (make-filled-box-stencil ext-X ext-Y)))

  <c'' e''>4. q8~ 4 <c' a'>16 q q q~ q4

}

Hope this is helpful--
