Troubleshooting
Even though the MU10 is exceptionally easy to use, it may occasionally not function as
you expect it to. If that happens, check the possible problems and solutions below
before assuming that the instrument is faulty.
No power.
No sound from the A/D
INPUTs.
No sound when playing
the MU10 from a com-
puter, sequencer or
external keyboard.
If you are using an AC adaptor, check that the
adaptor is properly plugged into both the AC outlet
and the MU10. (See page 12.)
If you are using batteries, check that a fresh set of
batteries is properly installed in the battery compart-
ment. (See page 13.)
Check that:
• The input sources are properly connected to the A/
D INPUT jacks.
• The A/D INPUT VOLUME sliders and the side
panel VOLUME slider are set to appropriate levels.
• The LINE OUT/PHONES jack is properly con-
nected to your audio equipment or headphones.
Check that:
• The LINE OUT/PHONES jack is properly con-
nected to your audio equipment or headphones.
• The side panel VOLUME slider is set to an appro-
priate level.
• All MIDI connections have been properly made,
making sure that the MIDI OUT of the external
device is connected to the MIDI IN of the MU10.
(See page 16.) Or, if you are using the TO HOST
terminal with a computer, make sure that the
computer is properly connected to the terminal and
that the HOST SELECT switch is properly set for
your particular computer. (See page 14.)
• The incoming MIDI data is appropriate. For
example, MIDI Volume or Expression messages
with a value of 0 will result in no sound for the
correwsponding Part.
• You have turned on the connected MIDI instrument
or computer before turning on the MU10. If you
haven’t, simply turning the MU10 off and back on
again may solve the problem.
