No, John, he's not the only one or the first. In 1997 I found Mac notation software called Concertware by Jump Music for about $30. It was fine for making sheet music, but there seemed to be some kind of glitch when patching in a midi keyboard, so when I tried to do that it really messed up my system, but that could also have been because I have a Motorola Mac or maybe I just connected the keyboard wrong. I had to reinstall and upgrade my system after that, but I have used Concertware for making gifs of notation and printing out music. It is capable of complex orchestrations, creating midis, multiple instrument sounds, etc. A sample of what I did was entering my son's tunes with the mouse and on-screen keyboard to create these gifs: click here

Previous discussions on the Mudcat include comments from other Mudcat Mac users regarding notation software.

I downloaded the Melody Assitant the day you posted the thread, but I haven't had time to do anything with it yet.
