Our smallest and simplest USB MIDI interface, USB Uno offers basic 1 x 1 operation and bus-powered mobility—and even comes with it’s own built-in USB and MIDI cables. What could be simpler? The M Audio Uno is a MIDI to USB interface which provides a simple, extremely inexpensive solution for connecting MIDI devices to USB-based Mac and PC computers. The compact injection-molded unit features built-in extension cables that simplify connections for novices. One cable connects to a computer via high-speed USB, while the other routes MIDI In and Out to devices such as the Oxygen8 MIDI controller and a synthesizer module. USB Uno also features MIDI activity indicators for each port. The unit is self-powered, thereby eliminating the need for yet another wall wart power supply and making it ideal for mobile use with laptops.
