Here’s an interesting app. On and On is a unique, three-dimensional music creation app.
Rather than be just one step-sequencer, On and On features three easy-to-use sequencers in 3D space, each of which can be edited in real-time by holding the iPhone or iPod Touch with the Home button at the user’s right (Landscape Left orientation).
The sequencer elements light up as they play, providing an engaging light show as the music plays!
Enjoy the colors and sounds as you create your own electronic music!
