Jeanene,Making a MIDI is easiest (IMO) in Noteworthy Composer. But I don't know if it is Mac-friendly. How about you try visiting their site and see if you can download the free evaluation version of the Composer and the Player--

Then let's talk in e-mail. We can toss tunes back and forth if you can run Noteworthy.
