Four different language folders will be displayed: English, 
German, French and Spanish.

Select the language you want to use and double-click on its 
folder.
“Reader Installer” will be displayed.
The Installer name may differ depending on the language you 
select.

Double-click on the “Reader Installer.”
Acrobat Reader Setup Dialog will be displayed.

Execute the installation by following the directions appearing 
on the screen.
After installation is complete, the Acrobat folder appears on 
your computer (in Hard Disk, as the default).
For information on using the Acrobat Reader, refer to the 
Reader Guide in the Help menu.

● Open Music System (OMS)

OMS allows you to use several MIDI applications on the Mac OS 
at the same time.

Double-click on the “OMS_” folder (English version only).
“Install OMS *****” will be displayed.

Double-click on “Install OMS *****.”
OMS Setup Dialog will be displayed.

After the installation, select “Restart.”

After restarting the Macintosh, you will find the “Opcode”/
“OMS Applications” folder on your computer (Hard Disk, as

Applications” folder (drag-and-drop it to the folder).
Refer to the “OMS_***_Mac.pdf” (English version only) 
how to use the application.

“OMS Applications” folder (drag-and-drop it to the folder).
In the “OMS Setup for YAMAHA” folder you will find the 
OMS Setup files for the Yamaha tone generators, which can 
be used as templates.

● 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].
