Level Alternative
When the level is set to High, the Alpha FXM is triggered to perform the next action when the user input changes
from Low to High. If the input then changes from High to Low, no action will be triggered because the level is set
to High. In other words, only a Low to High user input level triggers an action when Level is set to High. Similarly,
when Level is set to Low, the Alpha FXM will trigger an action only with a High to Low user input.
