Special thanks to my wife Liz for her love, support, and assistance throughout the seemingly endless task of developing the various versions of NoteAbilityPro.

Thanks also to Marc Petitmermet for all the time and energy he put in as a beta tester, and for the many, many helpful suggestions and bug reports he sent in.

NoteAbility Pro has had a long history. It was first designed for the NeXT computer in 1992, ported to Macintosh OS-X and eventually to the IPad. Along the way a number of people have generously provided code or programming concepts that have made their way into the program.

The MusicKit developed for Next Computers by David Jaffe and Julius Smith was used for playback scheduling and for many of the score and MIDI structures. Additional MusicKit code was developed by Doug Keisler, Lee Boynton, Leigh Smith and Stephen Brandon. All the MusicKit code was eventually replaced by my own scaled-down versions of their classes, but my classes were all based on the excellent work of these other developers.

Like most programmers, I rely on code fragments and classes that were downloaded from the internet and free to include in NAPro in accordance with the owners' copyright agreements. The following code made its way into one or several versions of NAPro:

Free Sound Fonts were used in NAPro and I acknowledge and thank the designers of these sound libraries which are available under the Create Commons licence and other licence agreements:
