Place note over bar

[AndrésPérezLópez]

Dear all,

it's a pleasure for me to write my first email in the list. I'm still very
new to Lilypond, so please forgive my ignorance.

We are in the development of an alternative music notation system, based on
proportional pitch and time representation. At the moment we have a
SuperCollider-based GUI for music edition and automatic transcription trough
MIDI.

We have considered using Lilypond for the graphical score output, due to its
wonderful features. Most of our required graphical notation symbols are
already implemented.

However, we are having problems with position of bar lines. We do use
regular bar lines for separating the bars but, in our proposal, the notes
are placed over the bars (and not at the right side, as in normal notation).
We still didn't find any property of the bar lines that would allow us to
place them in top of the first bar's note. 

Therefore, I would like to ask you if someone has an advice about the point.

Thank you very much for your attention.

Sincerely,

Andrés Pérez
