This is a rough demo using the GUI and play features (plus some extra stuff I've been making for my personal live use) from the Beads Java audio library (beadsproject.net). Mainly, it shows that you can do things that you can also do elsewhere (e.g., in Max or Supercollider) with perfectly good performance, and also shows off some features we've been working on. Tempo synch is easy and I've got a few handy GUI features like rampable and programmable sliders.
