Oscillating sound occurs
 
 
Is the value for any gain- or volume-related effects 
parameter set too high?
 
 
Lower these values.
 
 
 
 
When set to “USB In,” audio signals may, depending on 
the software settings, end up looping. You can use the 
following methods to prevent this from happening.
 
• Stop playback with the software, and set Soft Thru to Off.
• Switch the software’s audio input off.
• Change INPUT SELECT to “Bass 1–3.”
 
No change in preamp tone even after 
switching patches
 
 
Has the GT-10B been set to “System1–3” in Preamp 
mode (p. 73)?
 
 
When the GT-10B is set to “System1–3” in Preamp mode, 
the preamp settings do not change when patches are 
switched.
To make different preamp settings for individual 
patches, choose the “Patch” setting in Preamp mode.
 
Unable to change parameters with the knobs 
or dial
 
 
 
 
When the Assign Source is set to “INTERNAL PDL”,  
“WAVE PDL,” or “INPUT LEVEL” the effect parameter 
set as the Assign Target changes automatically.
If you want to be able to change the parameters 
manually with the knobs and dial, first switch off Assign 
to deactivate the Internal Pedal System.
 
 
 
 
When “INPUT LEVEL” is set for the Assign Source, the 
effect parameter set as the Assign Target changes 
automatically according to the level of the input from the 
bass (the playing dynamics).
If you want to be able to change the parameters 
manually with the knobs and dial, first switch off 
Assign.
 
Patch does not change
 
 
Is something other than the Play screen shown in the 
display?
 
 
On the GT-10B, patches can be selected only when the 
Play screen is displayed. Press [EXIT] to return to the 
Play screen (p. 25).
 
Parameters specified with Assign can’t be 
controlled
 
 
Could the effect be switched off?
 
 
To control a parameter using the EXP Pedal or 
footswitch, make sure the effect that contains the 
parameter you intend to control is switched on.
 
 
Is Prefernc ("preference") for Pedal Function set to the 
"System" setting?
 
 
Even when an assignment setting has been made for the 
patch, the setting made for Pedal Function (p. 48) takes 
precedence. To enable the setting made for the patch, for 
Pedal Function set the preference for the relevant 
controller to “Patch.”
 
 
Do the MIDI channel settings of both devices match?
 
 
Make sure that the MIDI channels of both devices match 
(p. 84).
 
 
Do the controller number settings of both devices 
match?
 
 
Make sure that the controller number of both devices 
match (p. 126).
 
 
Could the expression pedal be out of adjustment?
 
 
Although the unit’s expression pedal has been set for 
optimal operation at the factory, extended use and 
certain operating environments can result in the pedal 
going out of adjustment. Adjust the expression pedal (p. 
81).
 
MIDI messages are not transmitted/received
 
 
Are the MIDI cables broken?
 
 
Try another set of MIDI cables.
 
 
Is the GT-10B 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. 84).
 
 
When you send messages from the GT-10B, make sure 
the GT-10B is set to the settings appropriate for 
sending data.
