Xewton Music Studio offers a complete music production environment on the iPhone/iPod touch with features and a sound quality previously only known to desktop applications and expensive audio hardware.
It combines a piano keyboard, 21 professionally sampled instruments with sustain, a fully fledged 128-track sequencer, a note editor, reverb, real-time effects and much more on a user-friendly interface.
