Troubleshooting

If there is no sound, or if the GT-6B does not function as you expect, first check the following points. If the measures in this checklist do not resolve your problem, you should contact your dealer or the nearest Roland Service Center.

No sound / Volume is weak

❍Are the connection cables broken?

→Try exchanging the connection cable.

❍Is the GT-6B 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 the connected device.

❍Is the EFFECT LEVEL knob lowered?

→Adjust the EFFECT LEVEL knob to an appropriate position (p. 17).

❍Is Tuner/Bypass set to ON?

→The direct sound is not output by setting the Tuner/ Bypass to “On” (p. 56).

❍Is each effect set correctly?

→Use the “Meter function” (p. 59) to check the output level of each effect. If there is an effect for which the meter is not moving, check the settings for that effect.

❍Is “FV: Level” or “MST: Effect Level” specified as a Pedal Assign Target?

→Carry out the operation in accordance with the source.(p. 50)

The volume level of the instrument connected to INPUT jack is too low:

❍Could you be using a connection cable that contains a resistor?

→Use a connection cable that does not contain a resistor.

I Can’t Change Patches

❍Is something other than the Play screen shown in the display?

→On the GT-6B, patches can be selected only when the Play screen is displayed. Press [EXIT] to return to the Play screen (p. 10).

Parameters specified with control assign can’t be controlled as intended

❍Is the effect 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 to “Assignable.” (p. 63)

❍Do the MIDI channel settings of both devices match (when using MIDI)?

→Make sure that the MIDI channels of both devices match (p. 65).

*When “Omni On” is selected in Omni mode, messages on all MIDI channels are received, regardless of the MIDI channel settings (p. 65).

→Make sure that the controller numbers of both devices match (p. 66).

Volume level does not change with Foot Volume

❍Is “OFF” selected in Bypass EXP Mode (p. 55) and Noise Suppressor (p. 44)?

→If “OFF” is set in Bypass EXP Mode, note the following:

•When all effects are set to OFF, the analog bypass sound is output, and the volume cannot be controlled with Foot Volume (p. 44).

•When CHORUS or REV/DLY are the only effects being used, analog bypass sound is output for the direct sound, so only the effect sound is controlled with the FOOT VOLUME (p. 44).
