Oscillating sound occurs
❏ Is the value for any gain- or volume-related effects
parameter set too high?
→ Lower these values.
❏ Is the INPUT SELECT (p. 63) set to “USB In?”
→ 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
❍ Are you using the Internal Pedal System (p. 55) in
Assign?
→ 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.
❍ Is “INPUT LEVEL” (p. 51) set as the Assign Source in
Assign?
→ 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.
→ Check the on/off status for transmission of program
change messages (p. 86) and the settings for the
controller numbers to be transmitted (p. 86) .
