Case 2: Cannot shift to Suspend (*)
Is an application which uses the UM-2 running?
Exit the application which is using the UM-2.
The computer cannot shift to Suspend mode if an application
such as a sequencer is using the UM-2.
What is Suspend?
This is a function which minimizes power consumption
by shutting down the internal circuitry of the computer
and the peripheral devices while the power remains
supplied to the computer.
Case 3: UM-2 does not resume correctly from the
suspended state
When suspended, was the UM-2 still connected via the
USB cable?
Disconnect the USB cable, and then re-connect it.
On some computers when Windows resumes from the
suspended state, the UM-2 may fail to resume. If this occurs,
the USB cable connected to the UM-2 should be disconnected
and then reconnected.
Case 4: Windows hangs up (freezes) when
returning from the suspended state
Disconnect the UM-2's USB cable before suspending.
On some computers when Windows resumes from the
suspended state, it may hang up (freeze). If this occurs, the
USB cable connected to the UM-2 should be disconnected
before suspending.
When you once again wish to use the UM-2, make sure that
the computer has resumed correctly from the suspend state,
and then connect the USB cable to the UM-2.
Case 5: No sound
Are the USB cable, MIDI cables and audio cables
connected correctly?
Connect the cables correctly.
Are the volume controls of your sound module, audio
system, and application raised?
Check each of the volume controls.
Are the sound module settings correct?
Set the Computer switch of your sound module to the "MIDI"
position.
Troubleshooting
If the computer itself has a
suspend switch, the USB cable
connected to the UM-2 should
be disconnected before you
press that switch.
For a notebook computer,
some settings of the computer
may cause it to automatically
enter suspend mode when the
lid (LCD display) is closed, so
the USB cable connected to the
UM-2 should be disconnected
before the lid is closed.
Before changing the setting of
the computer switch of your
MIDI sound module, be sure
to turn off the power.
