If "DUAL CUBE" is not shown in the DEVICE SETTING screen of the DUAL CUBE BASS LX Editor, check the following points.
USB driver settings
If "DUAL CUBE" is still not shown after installing the USB driver, the unit may be set to use the standard OS driver instead of the dedicated USB driver. Change the setting to use the dedicated USB driver, then reconnect the USB cable.
To switch to the dedicated USB driver: Set the [AMP TYPE] knob to "SUPER FLAT," and turn on the power while holding down the [MEMORY] button.
Install the USB driver
A USB driver must be installed to use the DUAL CUBE BASS LX Editor on Windows or macOS. Download the USB driver from the BOSS website.
Note: On Windows 10/11, when the DUAL CUBE BASS LX is set to use the dedicated USB driver, the driver is automatically downloaded over the internet upon connecting to a computer.
