The short answer is "no", ...

... but maybe there is a solution for you.

My video generation code  uses a bit of scheme to export
music events to a file. The fragment

   \time 4/4 \tempo 4=120 \relative e' { e8 c4 r }

would be translated to

   [...]
   0.0 time 4 4
   0.0 tempo 2.0
   0.0 note 0.125 e'
   0.125 note 0.375 c'
   0.375 rest 0.625 NaP
   [...]

Lilypond's event-listener.ly was my starting point.

Have a look at
