On a Windows computer, you need to specify the MIDI Output device for any program that you use.
When you use a full featured MIDI program, you'll find that setting within the program in a preference called MIDI Setup or something similar.
If you are using a program that does not have such a preference setting (such as Windows Media Player), the program asks the Windows operating system what the system-wide MIDI Output default setting is, and then the program uses that setting.
In Windows XP and earlier systems, you could set a system-wide MIDI Output default using the Sound control panel. For some reason, Windows Vista and Windows 7 has taken away user access to this system-wide setting.
If you search the Internet, you'll see some solutions to this problem, such as the discussion on this page:
NOTE: I have not tried any of these solutions.
The Mac used to have a similar system-wide option that was accessible in the QuickTime control panel. That option on the Mac has also disappeared with OS X.

I have installed the 64 bit driver. The red light on the UX-16 is on and the MIDI In light is flashing. When I open the Yamaha USB-MIDI driver in the control panel, and select send all on the piano plays a note and the all stop releases the note. When I play a MIDI file it plays in Windows media player but does not activate the piano. I know the cables are correctly connected because my previous computer worked correctly. I am stumped.
