Launchpad X has a bootloader mode that allows the user to configure and save certain settings. The bootloader is accessed by holding the Capture MIDI button whilst plugging the device in.
The top two rows of pads can be used to set the USB device ID of the Launchpad X. The device ID ranges from 1 to 16, the selected ID is represented by a brightly lit pad. The default ID from factory is 1. If more than one Launchpad X is used on the same USB, each should have a different device ID selected.
The single yellow pad on the middle right can be used to toggle Onboarding. When Onboarding is ON, the Launchpad X shows up as a Mass Storage Device to provide a more convenient first-time experience. You can turn this off once you are familiar with the device to disable this Mass Storage Device.
The blue row of pads can be used to adjust the Launchpad X’s brightness level to something comfortable for the environment the device is used in. This control is also available on the Setup display when starting the Launchpad X normally. Note that low brightness levels may be required for Launchpad X to be powered on by certain devices.
The green pads on the bottom left can be used to display the version number of the Bootloader and the Application, respectively.
The single green pad on the bottom right can be used to start the Application.
