Troubleshooting
If a problem occurred while installing the driver, use the following procedure to 
reinstall it.
1
Uninstall the A-PRO driver as described in  “Removing the driver” (p. 
79).
2
Install the driver once again as described in  “Installing the Driver” 
(p. 12).
The A-PRO’s dedicated driver allows you to check or verify the settings.
The standard MIDI driver provided by the operating system (p. 73) does not allow you 
to change the settings.
1
Open the “Control Panel,” and then double-click the [A-PRO] icon.
If you’re using Windows 7, switch “View by:” to the icon display ([Large icons] or 
[Small icons]).
If you’re using Windows Vista/XP, and you don’t see the [A-PRO] icon, switch to 
[Classic view].
2
The “A-PRO Driver Settings” dialog box will appear. To modify the 
settings, make the changes and click [OK]. To simply check the 
settings, be sure to click [Cancel] after viewing the settings.
