Problem
No sound when playing
the keyboard on the MU5.
No sound when playing
the MU5 from a computer,
sequencer or external
keyboard.
Notes are cut off or
omitted.
When using a sequencer
or computer, an unusual
"flanging" sound occurs
and/or not all notes seem
to sound.
Even though Local control
function is set to off, the
MU5 continues to sound
when playing the built-in
keyboard.

Possible Cause and Solution
• Check that Local Control is set to on. (See page
35.) Also check the points for "No Sound"
above.
• Check all MIDI connections, making sure that
the MIDI OUT of the external device is con-
nected to the MIDI IN of the MU5, and that the
MIDI IN of the external device is connected to
the MIDI OUT of the MU5. (See page 20.) Or,
if you are using the TO HOST terminal with a
computer, make sure that the terminal is prop-
erly connected to the computer and that the
HOST SELECT switch is properly set for your
particular computer. (See page 17.)
• The maximum polyphony of the MU5 may be
exceeded. The MU5 can play no more than 28
notes at once.
• Check that Local Control is set to off. (See
page 35.) Also check the settings on your
sequencer or computer (such as "MIDI Echo" or
"Echo Back").
• This is nomal when routing the MU5 to a
sequencer (or computer) and the sequencer's
"MIDI Echo" or "Echo Back" is set to on.
