Sibelius is perhaps the best musical editor, for this is difficult to add something. Sibelius 6 is a giant leap forward in software for composers, teachers, students, arrangers, musicians and copyists of all kinds. The ability to create beautiful professional score. Synchronization with sequencers and DAW thanks to the support ReWire. Beautiful windows piano keyboard and guitar neck will do the job even easier. Simple chord symbols and display chords for guitar.
