Re: NRT options Part II

This may work.

I returned to having recordNRT using a duration argument.  This takes care of what I originally was looking for: the ability to render to a certain point in NRT. 

Along with what Julian was suggesting, I also made a method called section, which creates a new Score object from a section of the original score (and keeps the original score intact).

section has three arguments: start, end and configevents.  

configevents can contain a bundle array for any configuration events (as James mentioned).  These changes wouldn't break any existing code (recordNRT works exactly the same way by default).  section may be convenient for rendering just a part of a score (easier I think than going into a possibly long score and excising chunks).

I tried to warn against a couple of possible errors.  If configevents isn't an array, or use 0.0 as he time stamp, the function returns an error. 

How do these look?

Thanks for any suggestions, 

Josh

It does seem like, once the start time changes, all sorts of things can become a problem. For now I will put something together that simply truncates a score, and think more about altering start times.
