Has anyone ever used a beat box to generate beats or loops? There are quite a few of them on the market. These are more than just drum machines, they are creative pieces of hardware that allow you to start with a simple BASS DRUM beat, then add the Snare, the cymbal/high hat, then the Bass, and other synth sounds. This is how most techno and DJ music is built today.

I'm sure most keyboard manufacturers have 3-4 models that they currently sell.
