4.The Wizard reports that Windows has finished installing the software. Click “Finish”.Your Audiophile USB is ready for action.

Macintosh OS 9 Installation

NOTE: To use the Audiophile USB on Mac OS 9, you must also install Opcode’s OMS. This should be done BEFORE running the Audiophile USB’s Installer program. By installing OMS first, the Installer program will then be able to place the OMS driver in the proper folder. Then, after running the Installer, you will need to configure OMS. See the section, “OMS Configuration,” for more information on installing and configuring OMS.

1.Insert the Drivers CD into your CD ROM drive. Locate and open the Audiophile USB folder. Open the folder for your current Macintosh OS, and double click on the Installer program in that folder.

2.As the Installer loads the Audiophile USB drivers, you will be asked if you wish to place a shortcut to the Audiophile USB Control Panel on your desktop.This is your choice, but it’s probably a good idea to choose this option.You can always trash the shortcut if you find it unnecessary.

3.After you run the Installer, you may switch “On” your Audiophile USB. Your Audiophile USB is now ready for action.

OMS Configuration

To configure the Audiophile USB for MIDI on Mac OS 9.x, you will need to have Opcode’s OMS (Open Music System) installed first. OMS is a “MIDI Manager” program, and it is necessary to install this in order to run all OS 9 music programs that have a MIDI engine, i.e., programs that use MIDI.

You need to install OMS before you run the Audiophile USB’s driver Installer program. OMS is provided on the Drivers CD that came with the unit, and is located in the “OS 9” folder, or it can be downloaded from the M-Audio Website’s “Drivers” page. Opening the OMS 2.3.8 folder and double-clicking on the “Install OMS 2.3.8” program will install OMS in your system. Restart your computer, and continue with the driver installation (see previous section).

To configure your Audiophile USB MIDI in OMS, go to the Control Panel or Chooser under the Apple Menu, and make sure AppleTalk is turned off
