Been messing around with some of the AC mode and think I found a bug, but could just be me not understanding how it works.
If I add a ramp up/down function, and leave the two drop down boxes at the default settings of 0 and 100, it ramps up from 0 to 100 and then back down to 0, as would be expected. So I think the first drop down is the start/end intensity and the second drop down is the peak. However, if the first drop down is set to a higher value than the second drop down, I would expect an inverted result (starting at 100, going down to 0, and then going back up to 100) but that does not happen.
