Lilypond with Cubase/DAW for Musical

[JCHarris Music]

Hi,

I am working a large piece with voice, dialogue, etc. (a 'musical'). 
I have been using Cubase to mock up the various music bits. 
Surprisingly, I have found the latest scoring functions to be not 
half bad at all. Unfortunately, it still has some serious 
shortcomings in terms of adding lyrics, dialogue, stage directions 
and so on... the stuff that has to be in the final score and book.

Ideally, I would love it if Cubase had features for all that stuff, 
but until such a day, I'm wondering if anyone here has experience in 
using Cubase for this sort of thing and how you handle this.

I have been looking at LilyPond, which produces marvelous looking 
output, but it looks like it would be a terror to input this large 
project into directly. Fortunately, it does import MusicXML. So I am 
thinking of trying to export from Cubase as MusicXML into LilyPond 
and then add the other lyrics, stage directions, etc. in Lilypond.

Any suggestions on doing such a workflow?

TIA,

---JC
