The Edirol UM1EX is a simple USB MIDI interface offering one MIDI input & one MIDI output in a complete cable to connect your MIDI device directly to the computer. The UM-1EX's MIDI Out can also function as a MIDI Thru, making it the ideal 1x1 MIDI interface for use with separate input and output devices.

The UM1EX offers direct support for OS native drivers for Windows or Mac OS X, so that no installation disk is required. The Edirol UM1EX is perfect for small MIDI studios where only one MIDI device will be connected in close proximity to the computer and is also ideal for connecting a digital piano to a computer.
