Imagine a couple of dueling Wii controllers that squawk and beep rhythmically as you and a buddy wave them at each other, and you have an idea of what you can do with ZooZBeat software on an iPhone, iPod Touch or Nokia N95/N82/N93i.
The creators at ZooZ Mobile describe ZooZBeat as a “gesture-based mobile music studio,” and in their demos they did indeed control tonality and volume by varying the intensity and direction of a waving or shaking motion.
But if you want more fine-tuned control, an on-screen editor (shown in the screenshot) lets you use your fingertip to make changes.
ZooZBeat is available in either a “Lite” version ($1 for the Apple folks, free for the Nokias) or a full version ($3 all platforms, found at the link here) with support for voice recording, the ability to play with others, and more beat and instrument options.
Note: This link takes you to the vendor’s site. From there, you can follow the link to the iTunes App Store, where you can download the latest version of the software.
