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.
When correctly set up and optimized for your machine (which can be a b* on some), it is by far still the best Guitar Hero PC Clone out there. The custom song community pretty much went silent but some strong ones are still putting out Songs on a regular basis.
