I'm trying to build a very simple rhythm game (as a one-off art installation, not a commercial project) demonstrating a novel controller, but I've got an extremely short timeframe to do it in. Are there any open-source rhythm games or frameworks out there that I could use instead of writing such a game from scratch?

I could probably bang the code together in PyGame or Processing over a few days, but any time I can save on programming can be spent instead on the physical build, which would make the overall installation better. The requirements for the game itself are super simple -- I just need to scroll notes across the screen, register points based on how well the player matches them, and play a song (ducking one of the channels when a note is missed).

The custom controller is Arduino-based, sending its data as bytes over a serial port, so I don't need any fancy DirectX support. Just something that can run with <60ms latency.

It probably would be more effort to strip them down, but if you're curious both StepMania and Frets on Fire are open source.

Demo programming opensource, also links to some other demo/game engines :

Which one is a music framework? is it possible to view the source without downloading the files? – user25712 Jul 21 '13 at 2:33
