Good to hear!
But reverting the double stem doesn't work… although I suspect a

direction didn't work, so that I have to override it with up or down 
accordingly.

Any clues why this is the case?
The example I sent to you worked perfectly for me, so perhaps the 
\revert is in the wrong context?
I think it would be easier to find the culprit if you send a minimal 
example.

Hello Peter,

In 2.13.61 half notes in tab notation are distinguished from
quarter notes through a second stem.
Now I haven't seen this method before – it would seem natural
to me to draw a circle around the "tab note", the number, and
have only one stem like in normal notation.
The same would apply to whole notes, but of course without the
stem.

One may discuss about aesthetics, but I have seen this way of
displaying half notes and whole notes.


How can I achieve this kind of notation? Can I?

Yes! See the attached example. I tried to comment what I have done.

I is untested for working with harmonics - should the circle be
drawn around the fret number only,
or should it include the parentheses and the angle brackets?



In chords I would use a single circle (an ellipse, to be
correct) around all "tab notes" instead of drawing a circle
around every single one. This would be more difficult if
possible at all, I reckon, but it would be great to have this
possibility…

This is more difficult to implement, and, to be honest, I don't
know how.

HTH,

Marc

Half and whole notes in tab notation

[Peter Crighton]

In 2.13.61 half notes in tab notation are distinguished from quarter notes
through a second stem.
Now I haven't seen this method before – it would seem natural to me to draw
a circle around the "tab note", the number, and have only one stem like in
normal notation.
The same would apply to whole notes, but of course without the stem.

How can I achieve this kind of notation? Can I?

In chords I would use a single circle (an ellipse, to be correct) around all
"tab notes" instead of drawing a circle around every single one. This would
be more difficult if possible at all, I reckon, but it would be great to
have this possibility…
