Thank you all so much for taking the time & trouble to respond in such depth...insightful, interesting & very helpful. I have heard it said that Sibelius is the preferred route for music preparation, ie, score & parts for live performance, whereas Finale is the publisher's choice where the music ends up in book form or sheet music. Perhaps I should also have said earlier that I'm a Mac user.
