the following for possible solutions.
* If a message has appeared during operation, consult the fol-
lowing "Error Messages" section.
* If performance is incorrect when playing back song data carry-
ing the General MIDI/GS logo, check the following points:
* That the Device ID is set to 17 (p. 10)
° That the General MIDI System On/GS Reset Receive
Switch (p.19) is tarned on
The above settings were made when the M-GS64 was shipped
from the factory.
Cannot turn the power on

No sound
Is the power turned on for the other devices connected to the M-
GS64?
Is the volume knob turned all the way down?
Have you incorrectly connected to the MIDI IN and OUT con-
nectors? (p. 5)
Can you hear sound through headphones? (Try using the
Preview function p. 20.) If you can hear sound through head-
phones, the problem may be that the audio cable transmitting
the sound to the other devices is damaged or incorrectly connect-
ed, or that there is a problem with your mixer/amp/speaker sys-
tem.
Has the Expression pedal etc. on a connected MIDI device turned
the volume down?
A specific Part does not sound
Have you checked that relevant Parts are not being muted?
Is the volume level of the Part turned down? (p. 10)

Transmit channel of the connected MIDI device? (p. 10)
Cannot select the desired sound
Are you sending an incorrect Program number? (p. 21)
Sound is distorted
" If a specific sound or Part is distorted, lower the volume level of
that Part. (p. 10)

ume level.

Is the pitch of a specific Part incorrect by a semitone or more? (p.

tion. Or, transmit a Pitch Bend message with the central value
(40 00H).

be interrupted. (p. 8)
Is the same data being sent simultaneously to both MIDI IN A
and MIDI IN B?

Exclusive messages are not received
Make sure the "Sys Ex" setting (a switch for enabling reception
of System Exclusive messages) is not set at "oFF." (p. 11)
Does the Device ID number of the transmitted exclusive message
match the Device ID number of the M-GS64? (p. 10)
