Developer Psicada has introduced Earhoof, described as ‘a futuristic virtual instrument which turns your iPad into a rhythmic gradient of sound.’

Earhoof lets you layer multiple audio files and combine them with high quality digital signal processing.

Here’s what they have to say about Earhoof:

By continuously changing the sound parameters along the length of your device, Earhoof allows you to create highly expressive playable surfaces.

Its innovative internal rhythm engine allows you to easily play this surface, switching seamlessly between complex rhythms while remaining in complete control of the generated sounds. The result is a playing experience unlike any other, blurring the line between sequencer and instrument.

Here’s a video demo of Earhoof in action:
