Why don't we want to get printable scores here?  It would be interesting to see 
what \articulate has done to the music, possibly with the prospect of modifying 
it.  And in any case if we do want to get a printable score here, wouldn't we 
like it to be accurate?

Anybody have an idea on the GenericResourceDir problem?
