UM-1EX is not detected when making OMS or FreeMIDI settings
(Mac OS 9 users)
Is the UM-1EX detected?
• Reconnect the UM-1EX.
• If other USB devices are connected, connect only the UM-1EX.
• It is possible that the Macintosh did not correctly detect and initialize the UM-1EX. Leave the
UM-1EX connected, and restart your Macintosh. If it is still not detected, shut down your
Macintosh, and then restart it.
• In some cases, the UM-1EX will not be detected if you have connected it to the USB connector
located on the keyboard of the Macintosh. Please connect it to a USB connector on the
Macintosh itself.
