NoteAbilityPro is for producing professional music notation on Macintosh OS-X operating systems.

It was developed by Dr. Keith Hamel at the University of British Columbia, and claims to be one of the more sophisticated notation applications.

NoteAbility combines both musical intelligence and graphical flexibility in a direct and intuitive graphical user interface. Notate anything from simple melodies to complex avant garde orchestral music, play the score on your MIDI synthesizer or using Quicktime Musical Instruments and print a publishable copy of your score on any OS-X compatible printer.
