I'm assuming this problem is happening because the classes are template classes. Here's a cut-down version of the code that's giving me the problem:-

Code:
template<typename Time> class Note;

template<typename Time>
class Sequence : virtual public ControlSet {
public:
	// c'tors etc

public:
	struct EarlierNoteComparator {
		inline bool operator()(const boost::shared_ptr< const Note<Time> > a,
		                       const boost::shared_ptr< const Note<Time> > b) const {
			return musical_time_less_than (a->time(), b->time());
		}
	};

	typedef typename boost::shared_ptr<Evoral::Note<Time> >  NotePtr;

	typedef std::multiset<NotePtr, EarlierNoteComparator> Notes;

	void set_notes (const Sequence<Time>::Notes& n);
};
Basically, the above code compiles with gcc but when I try to compile it with MSVC (version 8) I get this error at the red line:-

error C2061: syntax error : identifier 'Notes'
Can anyone tell me what the problem is?
