A multi-OS rhythm game, written in Python, similar to Guitar Hero or Rock Band. Play guitar, bass or drums along with your favorite songs on your computer using either your keyboard or instruments. You can use your Guitar Hero or Rock Band instrument controllers. Separated audio tracks will mute when you fail to hit or sustain the required notes correctly to simulate a real concert-playing experience. Rock on, FoFiX doesn't require the original Frets on Fire to play, as it's a standalone-mod.
