Good news: White Noise Audio Software's free Memory plug-in
lets you sample loops of audio in real-time, adjusting both loop length
and filter cutoff for some crazy live loop-playing. Did I mention it's
free?

Insanely great news: You can control this mayhem using a $20-30 P5 Data Glove
game controller. I leave it up to your colossal stage presence to make
sure you look cyber-awesome and not just like a dork, but either way
I'll bet you have a great time.
