Troubleshooting
If there is no sound or other operational problems occur, first
check through the following solutions. If this does not
resolve the problem, then contact your dealer or a nearby
Roland service station.

No sound / volume too low

❍Are the connection cables broken?
→Try using a different set of connection cables.
❍Is the GT-6 correctly connected to the other devices?
→Check connections with the other devices (p. 12).
❍Is the connected amp/mixer turned off, or the volume
lowered?
→Check the settings of your amp/mixer system.
❍Is the OUTPUT LEVEL knob lowered?
→Adjust the OUTPUT LEVEL knob to an appropriate
position (p. 13).
❍Is Tuner/Bypass set to On?
→When the volume is set to “Mute” in the Tuner/Bypass
mode, even the direct sound will not be output by
setting the Tuner/Bypass to “On” (p. 58).
❍Is each effect set correctly?
→Use the “Meter function” (p. 60) to check the output level
of each effect. If there is an effect for which the meter
does not move, check the settings for that effect (p. 24).
❍Is “FV: Level” or “MST: Patch Level” specified as a pedal
assign Target?
→Move the controller to which it is assigned.
❍Is the power to the external device connected to the
SEND/RETURN jack off, or is the volume of the device
turned down?
→Check the settings for the connected device.

The volume level of the instrument

connected to INPUT and RETURN are

too low

❍Could you be using a connection cable that contains a
resistor?
→Use a connection cable that does not contain a resistor.

Patch does not change

❍Is something other than the Play screen shown in the
display?
→On the GT-6, patches can be selected only when the Play
screen is displayed. Press [EXIT] to return to the Play
screen (p. 13).

Parameters specified with control

assign can’t be controlled

❍Could the effect be switched off?
→To control a parameter using the expression pedal or
CTL pedal, make sure the effect that contains the
parameter you intend to control is switched on.
❍Is something other than “Assignable” selected for the
SUB CTL 1,2 function setting?
→When operating a foot switch connected to the SUB
EXP/SUB CTL 1, 2 jack, set the SUB CTL 1, 2 function (p.
63) to “Assignable.”
❍Do the MIDI channel settings of both devices match?
→Make sure that the MIDI channels of both devices match
(p. 65).
❍Do the controller nimber settings of both devices match?
→Make sure that the controller nimber of both devices
match (p. 66).

MIDI messages are not transmitted/

received

❍Are the MIDI cables broken?
→Try another set of MIDI cables.
❍Is the GT-6 correctly connected to the other MIDI device?
→Check connections with the other MIDI device.
❍Do the MIDI channel settings of both devices match?
→Make sure that the MIDI channels of both devices match
(p. 65).
❍When you send messages from the GT-6, make sure the
GT-6 is set to the settings appropriate for sending data.
→Check the on/off status (p. 66) for transmission of
program change messages and the settings for the
controller numbers to be transmitted (p. 66) .
