Problems can arise when your hardware device is too old or not supported any longer. This will help if you installed an incorrect or mismatched driver. The Uno is a complete USB-to-MIDI solution, equipped with a USB connection to your computer, and a 1-in/1-out 16-channel MIDI connection to your MIDI devices.The Uno works for Windows and Macintosh operating systems. Try to set a system restore point before installing a device driver. It is highly recommended to always use the most recent driver version available. The defect affects only the MIDI input and causes the MIDISPORT Uno to distort incoming MIDI data resulting in random notes, inaccurate note on/off messages, as well as pitch bend. M-Audio has identified a defect in a manufacturing run of its popular MIDISPORT UNO 1x1 MIDI interfaces. Changed installer to use static product and package ID GUIDs versus dynamic build time generated GUIDs Note:


Changed build to use Avid signing certificate in place of the expired M-Audio signing certificate. Updated driver installer to use a newer version of the Microsoft Visual C++ 2005 Service Pack 1 Redistributable installer which fixes this install failure. Addressed Microsoft Visual C++ 2005 Redistributable installer issues.
