Items to check
Are the connection cables broken?
Is the GT-001 correctly connected to the other devices? Check connections with the other devices.
Is the connected amp/mixer turned off, or the volume
lowered?
Is the [OUTPUT LEVEL] knobs lowered?
Is Tuner set to On?
Is each effect set correctly?
Is "FOOT VOLUME: LEVEL" or "MASTER: PATCH LEVEL"
specified as an assign Target (p. 26)?
Is INPUT (GUITAR/MIC) set correctly (p. 33)?
Is the "DIR.MONITOR" (p. 34) set to OFF?
Is INPUT (GUITAR/MIC) set correctly(p. 33)?
Could you be using a connection cable that contains
a resistor?
Is the value for any gain- or volume-related effects
parameter set too high?
Could the USB PRIMARY (p. 34) parameter " LOOP" (LOOP
BACK) be turned ON?
Could the preamp "PREFERENCE" (p. 35) be set to
"SYSTEM 1–3"?
Is "INT PEDAL" or "WAVE PEDAL" set as the ASSIGN 1–8,
SOURCE in Assign (p. 26)?
Is "INPUT LEVEL" set as the ASSIGN 1–8, SOURCE (p. 26)?
Is something other than the Play screen shown in the
display?
Could the effect be switched off?
Could the pedal function "PREFERENCE" (p. 35) be set to
"SYSTEM"?
Do the MIDI channel settings of both devices match?
Do the controller number settings of both devices
match?
Is the USB cable broken?
Is the GT-001 correctly connected to the other MIDI
device?
Do the MIDI channel settings of both devices match?
When you send messages from the GT-001, make
sure the GT-001 is set to the settings appropriate for
sending data.
Action
Try another set of MIDI cables.
Check the settings of your amp/mixer system.
Adjust the OUTPUT LEVEL knobs to an appropriate position.
When the OUTPUT is set to "MUTE" in the Tuner mode, even the direct
sound will not be output by setting the Tuner to "On" (p. 39).
Check the settings of each effect.
Move the controller (pedal) to which it is assigned.
Make the correct setting.
Set to ON.
Make the correct setting.
Use a connection cable that does not contain a resistor.
Lower these values.
Depending on the software settings, audio signals may 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.
If PREFERENCE: PREAMP is set to "SYSTEM 1–3, " the preamp settings
won't change when you switch patches.
If you want to make preamp settings individually for each patch, set
the above setting to "PATCH. "
When the ASSIGN –8, SOURCE is set to "INT PDL (INT PEDAL)" or "WAVE
PDL (WAVE PEDAL)", the effect parameter set as the Assign Target
changes automatically.
If you want to be able to change the parameters manually with the
knobs, first switch off Assign to deactivate the Internal Pedal System.
When "INPUT LEVEL" is set for the ASSIGN 1–8, SOURCE (p. 26), the effect
parameter set as the Assign Target changes automatically according to
the level of the input from the guitar (the playing dynamics).
If you want to be able to change the parameters manually with the
knobs and dial, first switch off Assign.
On the GT-001, patches can be selected only when the Play screen is
displayed. Press [EXIT] to return to the Play screen.
To control a parameter using the expression pedal or footswitch, make
sure the effect that contains the parameter you intend to control is
switched on.
If the preference is set to "SYSTEM, " the patch assignment will be
ignored. If you want to enable the settings of the patch, change the
preference for the corresponding parameter to "PATCH".
Make sure that the MIDI channels of both devices match (p. 36).
Make sure that the controller number of both devices match (p. 36).
Try another USB cable.
Check connections with the other MIDI device.
Make sure that the MIDI channels of both devices match (p. 36).
Check the on/off status for transmission of program change messages
(p. 36) and the settings for the controller numbers to be transmitted
(p. 36) .
