Kneed cue-notes

[Ruud van Silfhout]

Hi,

Some time ago I asked how I could create a piece of music
with kneed cue notes. Until now I still do not have the desired result.

This is what I try to do (see music below):
I have two staffs called tenor and bass. On these staffs I have
multiple voices. A voice with the tenors music accompanied by
tenors text (which I left out to simpify the example a bit) and a voice
for the cue notes.
The same goes for the bass staff.

The reason to have separate voices for the cue notes is that I can
size these cue notes independently from the normal notes and that I
can reuse the tenor and bass music and lyrics in parts, which are
differently typeset. shouldn't this be possible? Otherwise I can't reuse
the normal bass and tenor music??

In order to change from staff I use the \change
command as I found in the beam-isknee.ly example.

Once this works, I also need the following: The tenor voice is normally
typeset with the G_8 clef. For the organ music in the cue notes,
the clef is a normal G.

What is the correct way to do this?

I am currently working on lily version 2.2.0, cygwin
