USB MIDI Driver
To operate the MIDI instrument from your computer via USB,
you’ll need to install the appropriate driver software.
The USB-MIDI driver is software that transfers MIDI data back
and forth between sequence software and the MIDI instrument
via a USB cable.
First install OMS before you install the USB-MIDI driver. Also,
after installing the driver, you will need to set up OMS (see page
64).
Start the computer.
Insert the included CD-ROM into the CD-ROM drive. The
system displays the CD-ROM icon on the desktop.
Double-click the CD-ROM icon and double-click the “Install
USB Driver” icon in the “USBdrv_” folder to display the fol-
lowing installation screen.
The “Install Location” box displays the destination of the
installation. If you wish to change the destination disk or
folder, use the [Switch Disk] button and the pop-up menu to
specify the desired destination.
Click the [Install] button. The system displays the following
message: “This installation requires your computer to restart
after installing this software. Click Continue to automatically
quit all other running applications.” Click [Continue].
For Macintosh Users
• After the installation is complete, you may possibly encounter an
error message warning that the installer did not close. In this
