Absolutely - that's why I wrote d-Performance, because there was a
demand for such a feature. I also added things like the Mute Staff so
that the user can turn off the voice they are playing and so on. 

Until someone writes a much better MIDI generation for Denemo the best
quality MIDI output would be via LilyPond's \midi command, which as you
say is complicated. We don't even have a command to generate it from
Denemo at the moment, though it would be easy enough to do, but we
wouldn't have the cursor moving in step without quite a bit more
work(*).

(*) as a matter of history, we used to spawn an external player and then
move the cursor from within Denemo and this worked surprisingly well.
But it would be a fair bit of work (and I don't really know quite how
good LilyPond's MIDI generation is, I have never really tried it - I
have seen discussion about handling things like ritardando and so on).
