800 xl game: music maker

[Starbug]

Hello Atari lovers. Does anybody remember the game "music maker" for the 800 xl. I can't find any reference to it. There is a "music major" in the games list but that definitely isn't it. It was a great game, I'm suprised I can't find it anywhere. I'm pretty sure it was called music maker but I could be wrong. Please help
