It’s amazing how many interesting granular sequencing sampler Apps there are for iOS. You can add Earhoof to that list. I picked up an iConnect MIDI2 just for Apps like this one. $4.99 available now.
“Earhoof is a musical instrument which combines a powerful sound generating engine with an innovative rhythmic playback mechanism. Simply by holding the surface, complex rhythms trigger and seamlessly transition, while the sounds the internal sequencer generates continuously vary as you glide your fingers across your device. Even though Earhoof is easy to play, its flexibility makes it easy to create your own techniques.” – psicada.com
