Four tracks (six on the iPad) for harmonizing with yourself or playing all the instruments in quick demos. Tap to start recording and again to stop. Everything you sing or play in between gets looped, ad infinitum, as you build your tune layer by layer.
WIRED Gesture-based buttonless interface. Can combine two tracks into one to free up space. Click track keeps you on tempo.
TIRED Complicated gestures make it difficult to access some features. Tough to get the hang of timing for seamless loops.
