I've always been curious about the algorithm used in Parappa to determine whether the off-rhythm beats are "cool", or just screwups. Any ideas?


You got me curious enough to throw together a quickie prototype. By setting up a beat loop run by the computer, and having all inputs by the player quantized, I was able to quickly get something that sounded "good" no matter what goofy keys I hit. I'd guess that the game simply measures how far off the input is from key moments in a measure--probably to the resolution of 8th notes.
