PlayStation Blog: When you hear the term “interactive music” you might think of “rhythm games” such as Guitar Hero, Rock Band, Frequency, or others of that nature. Dyad’s music system is very different from those games. There’s no beat matching or imposed rhythm in the game. The music doesn’t dictate play, nor does it judge you. Dyad’s music is reactive, meaning it’s mixed dynamically on the fly, based on the current game state and how you’re interacting with it. Each time you play a level, the music is different — playing Dyad can be viewed as a “performance” in a sense.
