I've had a look at this now. What you are doing is deleting all the
notes & then putting in a new set. This could be done by a script, doing
d-RemoveNoteFromChord until it returns #f and then doing d-PutNoteName
on the notes desired. I haven't written this - you may uncover lacunae.

However, both these approaches lose things attached to notes (e.g.
fingerings). Perhaps that is ok, since the note is changing, so perhaps
those things would need to change anyway.

Another point, your function returns an empty string - the convention
for anything that isn't asking for a value is to return a boolean, in
this case TRUE if notes were added FALSE in such cases as not on a chord
etc.

Thanks for pushing on with this stuff, it is really needed to make
Denemo look complete.
