Installing the UM-3 driver
Use either OMS or FreeMIDI as the MIDI driver.
The included UM-3 driver is an add-on module for using the UM-3EX with OMS or FreeMIDI.
OMS can be found in the OMS 2.3.8 E folder within the OMS (Mac OS 9) folder of the CD-ROM. If
you would like to know more about OMS, refer to OMS_2.3_Mac.pdf which can be found in the
same folder.
* Either OMS or FreeMIDI must be installed in your Macintosh, as appropriate for the sequencer software you
are using.
* If you install OMS after installing the UM-3 driver, you must install the UM-3 driver once again.
If a UM-3EX is already connected to your Macintosh when you install the driver, a message like
the following will appear when the Macintosh is started up. Perform the steps described below as
appropriate for the message that is displayed.
If the screen indicates:
"Software needed for the USB device "UM-3" is not available. Would you like to look for the
software on the Internet?"➔ click [Cancel].
1. With the UM-3EX left unconnected, start up Macintosh.
* Disconnect all USB cables other than those for your keyboard and mouse, and restart your Macintosh.
2. Exit all currently running software (applications).
3. Prepare the CD-ROM. Insert the CD-ROM into the CD-ROM drive of your Macintosh.
4. Double-click the UM-3 Driver-E Installer icon (found in the Driver E (Mac OS 9) folder of the CD-
ROM) to start up the installer.
5. Verify the Install Location, and click [Install].
The installation location will be shown differently depending on your system. Make sure that you
have selected the startup disk for the system you are currently using.
