i-MX1 is a MIDI interface cable which enables an iPad or iPhone to be connected to any MIDI instrument. Setup is fast and easy - simply connect the i-MX1 between your iPad/iPhone and a MIDI instrument (such as synthesizer, electronic drum kit, digital piano) before launching the Apps from your iPad/iPhone. You can play and control the App's sound using the real interface of the instrument. There are also dedicated applications for Yamaha synthesizers which will expand the functions of your instrument. The Faders & XY Pad MIDI Control application controls your synthesizer's sounds by sending MIDI control change messages from the iPad. Keyboard Arp & Drum Pad is an application that transmits notes to the synthesizer. All the applications from Yamaha will increase the joy of playing instruments by combining the unique interface of your iPad/iPhone.
