I recently bought an Akai APC40 MKII. It has a matrix of 8 buttons across, 5 buttons down. After I midi map my videos to those buttons, some of the buttons in the top row do not trigger the videos assigned to them. Instead, a few of those top row buttons trigger (and light up the button of) videos in the second row.
What on earth is going on? (And yes, I've selected 'Akai APC40 MKII' as my device in the pop-up menu that displays after you go into edit midi).
