User Guide

Bootloader

Launchpad MK2 has a bootloader mode that allows the user to configure and save certain

settings. The bootloader is accessed by holding the Session, User 1, User 2 and Mixer buttons

while plugging the device in. Figure 1 shows the functions of the bootloader.

The top two rows of square buttons can be used to set the device ID of Launchpad MK2. The

device ID ranges from 1 – 16 and the selected ID is represented by an orange button. This also

sets the USB identity, which ranges from 69h to 78h.

The next two rows can be used to set the communications channel for User 1 and User 2 layouts.

Row 3 represents User 1 (channels 1 – 8) and row 4 represents User 2 (channels 9 – 16). Certain

channels are reserved and cannot be selected – these are represented by a dimly lit red button.

Available channels (6 – 8 for User 1, 14 – 16 for User 2) are represented by dimly lit blue button.

Selected channels are represented by a bright blue button.
