There is an additional row of 8 push button labeled 0 (dotted-circle) to 7.

Both LCD and all 12 keys form a larger (480x270) LCD capable of touch interaction.

In an alternate presentation, side LCD can be considered as 3 individual buttons each.

Indices for Behringer Devices

Keys

XTouchMini has 8 encoders with 8 "multi-led" displays, and 16 buttons with LED.

There is a slider and two more buttons on the side. These two buttons were meant to be used as "page" switches between 2 pages labeled A and B. For simplicity, we chose to not change the use of these two buttons and they should be programmed as Page Loader activation. The currently loaded page can be highlighted, like on the above photograph, Page A is loaded.
