My friend finally released his small and efficient joystick to MIDI mapper called Midity. It supports any game controllers you might have (of course you’ll have to configure them first) from simple joysticks to dance pads and even Wiimotes – anything Windows recognizes. If you’ve ever played around with Rejoice and similar programs, you definitely need to check this out.
I got an idea to use my dance pad as a MIDI controller using Rejoice to convert the HID keypresses into MIDI notes. I can’t find a working download link or any info about Rejoice, so that you’ll have to find yourself if you ever want to try this. (hint: p2p)
Oh yeah, and excuse the crappy dancing.
Edit: Since I’ve been getting a lot of Google hits on this post looking for dance pad to midi converters, check this out: midity
