Marbles Trigger Sounds in Ball Beats Physical Step Sequencer

You probably won't even guess what the Ball Beats does just by hearing its name.

Fortunately, there is media coverage and even a video of the thing in action, so the mystery needn't plague anyone.

Basically, Ball Beats (supposedly on sale and priced at $199 / 155 Euro) is a physical step sequencer spread over an 8 x 6 grid.

A light sensor is built into each point, which means that a sample is triggered whenever a marble is placed on it.

Furthermore, light sensors built into the sides of the grid can be configured for different actions as well.

The link to a software interface is maintained by an USB connection. That same interface can send MIDI signals to whatever audio software one prefers most (the video uses Ambleton Live for the sound).
