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.
