■ Installing the UM-1 driver
Use either OMS or FreeMIDI as the MIDI driver.
The included UM-1 driver is an add-on module for using the UM-1EX 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-1 driver, you must install the UM-1 driver once again.
