Did you plug in the USB cable, or unplug it while an software was running?
Exit all software that are using the UM-2EX, and re-connect the UM-2EX.
Is your computer in Suspend or Sleep mode?
If so, get your computer to resume normal operation, then exit all software that are using the UM-
2EX. Next re-connect the UM-2EX.
Are you running multiple software?
If multiple software are running simultaneously, an error message may appear. If this occurs, click
[OK]
and exit the other software.
Even if an software window is closed, it is still running if it appears in the taskbar. Be sure to exit
unneeded software displayed.
Was a heavy processing load experienced while using the UM-2EX, such as accessing
the CD-ROM drive or a network?
If an operation involving a heavy processing load is performed while the UM-2EX is in use, it may
not operate correctly. If this occurs, stop playback/recording, and then try resuming playback/
recording. If you are still unable to play back/record, exit all software that use the UM-2EX,
disconnect the UM-2EX from the computer and then reconnect it.
Operation becomes unstable when the computer is started up with the UM-2EX
already connected
Please start up your computer with the UM-2EX disconnected, and then connect the UM-2EX. On
a computer that uses a USB keyboard, starting up the computer with the UM-2EX already
connected may cause operation to become unstable. In this case, start up the computer with the
UM-2EX disconnected, and then connect the UM-2EX.
Problems When Using the UM-2EX
Sound is interrupted during MIDI playback
Playback or recording halts midway through, and then becomes impossible
Operating system becomes unstable
