Musyc - Physics Music Maker

Musyc is a touch-driven music studio that turns your gestures into sound with a physics-based engine. No piano keyboard is needed—draw shapes and hear melodies while watching sounds bounce on the screen. It features 88 instruments across 22 groups crafted at Fingerlab, plus a set of physical and musical tools to explore.

Real-time recording, a built-in mixer, 2 effect channels with multiple effects, inter-app audio, and exports to Dropbox, SoundCloud, Mail, iTunes. Video export to Facebook, Vimeo, and Photo Library is supported, and you can unlock the full feature set via in-app purchases.
