DIGMEE the Interactive Music Sequencer sound engine
The Diverse Interactive Game Music Experience Enhancer or DIGMEE can change music to events in the game. With this you can highly enhance the players gaming experience and bring your game to a whole new level. There are some example samples included to start with. Making DIGMEE work is not hard but some experience using music apps for preparing the samples is helpful. I have made a tutorial on YouTube to help you with the process.
Bunny Ball is the first game using this system. You can download it here to see (or better hear) it in action: http://appstore.com/bunnyballs
