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.

then on again.
