Sam's Final Project: PLOrk PLOrk Revolution

A 2-player typical PPR setup.

What is PPR?

PPR is an interactive multiplayer drum machine. Using PSX controllers and DDR pads as input devices, players can toy with individual beats and melodies through the built-in sampler. Once they've found a cool pattern, pressing start will record the sound and time for each input note. Pressing start again stops recording and transmit the musical data over to the host computer, which cleans up the timing and plays it along with the loop.

To see it in action, check out this demo video

How do I play PPR?

Unfortunately for the end-user, PSX-USB adapters, and even PSX controllers themselves, do not have a standardized interface. Not only are buttons mapped differently, some adapters may interpret the arrows as a directional-pad, requiring a completely different way of interpreting the HID signals (and making simultaneous L + R impossible on a DDR pad). While this is bad enough on its own, the piratic nature of PSX-USB adapters makes them very prone to shorts, as one of my adapters experienced.

In short, you probably should take the video as evidence that it worked at one point and not attempt to get it working on your computer.

I'm too lazy to do all that!

Well, then listen to some prerecorded examples! That's so easy that even you can't whine about it!
