highlight notes while playing MIDI

When I play the MIDI file I'd like to see, in the PDF preview, the notes
being played in each moment. 

It seems that upcoming Frescobaldi 2.0 could support this feature:

"Frescobaldi 2.0 can maybe have such a thing. Of course the PDF preview does
not know the notes, but it does have the positions (if point and click was
used) and Frescobaldi 2.0 has a tokenizer that works all the time and so it is
possible to see what object a point and click link points to. The built-in
MIDI player could also look at the document and so maybe it's possible to
implement highlighted notes (in text and/or PDF preview) while playing.

And other things like play from cursor, etc. "
