Score follower

[Konstantin]

Hello,

I want to create a score follower, that is a software which shows the scores and
the current position I am playing on my keyboard. I tried some rendering engines
(Guidolib, Musescore, ...), but Lilypond has the best graphical output. Now I
need informations about the scores like pitch, duration, voice, x-y-coordinates
and page.
I tried \displayMusic, but it seems there is no graphical information. I also
tried -dbackend=scm, but it seems there is no pitch/voice information.

Has anyone ever been faced with the same problem and can help me?

Viele Grüße,


Konstantin
