Troubleshooting
Case 3: No sound
◆
Are the USB cable, MIDI cables and audio cables connected correctly?
→
Refer to" 2. Connections with the MIDI Equipment" (P.12) , and 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.
Before changing the setting of the computer switch of your MIDI sound module
(SC-88Pro etc.), be sure to turn off the power.
◆
Do you use only OMS?
→
When using OMS on your Macintosh, it cannot operate correctly. When FreeMIDI is installed,
delete the files related to FreeMIDI from the “Extensions” folder.
Case 4: Notes are sounded twice (Notes are recorded double)
→
Refer to the owner’s manual for the sequencer program that you are using. If the “UM-4
Driver” is selected in the MIDI input port setting, cancel this selection (un-check it), and
select (check) only the port (UM-4 Port 1–4) to which the MIDI device you wish to record is
connected.
* When you select “UM-4 Driver,” all of the four items “UM-4 Port1, 2, 3, 4” will be selected.
However if “UM-4 Driver” and “UM-4 Port 1–4” are selected, the selected port will be
sounded in duplicate.
Case 5: The UM-4 does not recover correctly from sleep mode.
→
After your Macintosh has been in sleep mode, exit the software and re-start it.
* We recommend that you make Energy saving settings in the Control panel so that your
computer does not enter sleep mode.
