As if we needed more examples of awe-inspiring iPad music apps, here comes a new app called Beatsurfing.

Beatsurfing wowed me the first time I saw it in action. Admittedly, I wasn’t sure then what the app was actually doing, so my admiration was influenced by some measure of mystery. But now that I have learned more about the app, I have to say that it impresses me no less.

Developed by Herrmutt Lobby and Yaniv De Ridder, Beatsurfing is an organic MIDI controller builder. Say what? Until very recently, I had no idea what that meant either.

Essentially, Beatsurfing is a MIDI controller designed to control any MIDI-enabled device, including software, hardware, and even other iPad apps. That may sound boring to someone who has no business controlling MIDI thingamajigs, but wait until you see how it basically works in the video above.

The app lets you configure your own controller by giving you a virtually infinite supply of lines, polygons, circles, and faders. Each of these object types has its unique function. And when drawn together, they can be tapped and swiped across to create a cool symphony of sounds and a spectacle of colors to boot.

Beatsurfing for iPad is available now for $11.99. Quite a hefty price for an app, I know. But come to think of it, how many other organic MIDI controller builders are there in the App Store?
