Setting up OMS
* Before setting up OMS, change the setting of the MIDI device connected to the UM-1 to
avoid transmitting the MIDI time clock signal. For instructions on how to change the
setting, refer to the owner's manual of the MIDI device you have.
* When you install the USB MIDI Driver and set up OMS, two MIDI devices named "Roland
UM-1" will be detected. One of them is the MIDI device connected to the UM-1, and the other
is the UM-1 MIDI interface itself. You need to change the name of the MIDI device connected
to the UM-1 so that the two can be distinguished. Please refer to the next procedures.
1.
Make sure that the UM-1 is connected to your Macintosh, and power up your Macintosh.
