USB

Here you can make USB-related settings for when the GX-1 is connected to a computer via USB.

Parameter	Value	Explanation
EFX OUT LVL	0–200%	Adjusts the level of audio output to the computer after passing through the effects of the GX-1.
MIX LEVEL	0–200%	Adjusts the level of the input sound from the computer. With this setting, the input sound from the computer is mixed into the final stage of the GX-1 signal chain.
DRY OUT	0–200%	The guitar sound that is input to the GX-1, is output without change (DRY sound); it is not processed by effects.
DRY TO EFX (INPUT TO EFX)	0–200%	Adjusts the input level from the computer to the GX-1’s effects.
DIR.MON. (DIRECT MONITOR)	Selects whether the sound of the GX-1, is output to the PHONES jack or the OUTPUT jacks. This setting cannot be saved. It will be ON when the unit is powered-on.
	OFF	Turn this off if the audio data is being passed through within the computer. In this case, you won’t hear the sound unless the computer is set to through.
	ON	The sound of the GX-1 is output directly. Turn this on if you’re using the GX-1, by itself without connecting to a computer. (If this is off, only the sound that is input to USB will be output.)
LOOPBACK	OFF, ON	Turn this ON to send the sound mixed from the computer with the GX-1’s effect sound to your computer.
USB DRIVER	VENDOR	When connecting to a Windows or macOS device, use the “VENDOR” setting. Install the GX-1 driver that you downloaded from the BOSS website.
USB DRIVER	GENERIC	When connecting to an iOS device, use the “GENERIC” setting. The unit operates using standard iOS functionality. Some functions may be limited when compared with the VENDOR setting.
