The reason why the recommended Launchpad variant is the MK2 or older is because newer models such as the Launchpad X or the Launchpad Mini Mk3 or even any variant of the Launchpad Pro are “too smart” and have internal processing that conflicts with the functionality of the Madeon-style DJ setup.
The user modes on these models do not provide use of the scene launch buttons on the Mk3 models which is a crutial detail for a setup that is faithful to the original.
