This is the first cable that connects instruments that have USB MIDI (vs. regular 5-pin DIN MIDI) to iDevices. The i-UX1 works with the iPad/iPhone/iPod touch. Following an intuitive setup process, the i-UX1 quickly expands the functions of Yamaha MIDI instruments, enabling players to easily launch Yamaha's innovative Apps, such as Piano Diary and MusicSoft Manager. It also allows users to edit the sound of their instruments from the iPhone, or the larger display of the iPad.
