I see... would it be too much to ask you to send your engraver to me (off list 
if you prefer)? That's of course assuming you developed one for your own music. 
Normally I don't mind doing some research and experimentation on my own, but in 
this case --

- This is for a concert that will be in mid-May, for which I'm writing a new 
piece and I will have to rehearse everything else as well.

- I'm also turning some students loose on a big SuperCollider interface to 
connect webcam (and maybe iphone) data to sound parameters. Lots of bugs 
popping up there. That will probably be on the same concert.

- Full-time teaching schedule.

I worry that I wouldn't have time to cobble together enough scheme knowledge 
(starting from nothing) to put together my own engraver... by which I mean, I'm 
really under serious time pressure and if this is going to take, oh, more than 
a couple of hours, it's more than I can afford right now. (I'm estimating 10-15 
hours.)

I'd really appreciate it -- otherwise, I'll find another way to notate the idea.
