About the USB connector
• In order to use MIDI on your computer, you will need application software that is appropriate for your
computer and that meets your needs.
• If you want to use a USB cable to connect the PF-500 to your computer, you must connect the USB
cable before turning on the power of the PF-500.
Also, do not turn the power of the PF-500 on or off while application software that uses USB MIDI is
running.
• The PF-500 will begin transmission a short time after the USB connection is made.
• If you are using Windows 2000, problems may occur on your computer when your computer starts up.
In this case, turn on the power of the PF-500 when your computer is running.
• When using a USB cable to connect the PF-500 to your computer, make the connection directly without
passing through a USB hub.
• Depending on the state of your computer, the operating state of the PF-500 may become unstable. Do
not use your computer in a way that causes it to enter an unstable state.
