The layout determines the MIDI note number that the buttons send and receive. Layout 0 is
Session layout. This is best for writing software that uses Launchpad MK2 as a grid as it is easy to
navigate by adding and subtracting - adding 1 moves to the right 1 button, adding 10 moves up
one button.
Layout 1 is User 1 or Drum layout. This is ideal for situations where Launchpad MK2 must launch
samples or deal with musical MIDI.
Layout 2 is User 2 and is the same as Session.
Figure 3 shows these layouts in hexadecimal, figure 4 in decimal and figure 5 in note names. In
each of these images Cs are coloured red and Fs are coloured blue.
