It is a bit annoying that most of the tutorials are made for Stadium XL. Hence I have not found a solution to this problem. My unit is updated (1.3.2, the latest update at the moment).
When you press the MODE (FS6) button and hold it for a few seconds you open the "more" window that allows you to choose further options. The info, stopwatch, metronome, save, mute and clip functions are available. The problem is that the rest of the modes (in my case STOMP A, STOMP B, PRESET and TRANSPORT) are not available => (grey colour/ assigned buttons FS8 - F11 are not lit). In all the tutorials for the Stadium XL you can access these modes just by clicking a button. Why is my Stadium Floor not working like this? Am I missing something or is this a known bug?
In comparison to this tutorial for Stadium XL you can clearly see the issue:
