This purchase includes an immediate download of the PDF and Finale files for the score and parts. Finale 2014 or later is required to open the Finale file. If you have an older version of Finale or if you use Sibelius, Dorico or Logic X, you can import the score with the included MusicXML files. Most other music apps will be able to open the included MIDI file. Note: when opening the Finale, you may not have the fonts that the file requires. This is no problem. Just navigate to the Document Menu, Set Default Music Font, and select Maestro. Email matt@mattrileymusic if you have any questions.
