I have never needed to use the ducking parameter much and tend to leave it at 0 or very slightly above 0. However, I was messing around just now and thought I would try and get better acquainted with it. According to the manual a positive value should suppress the delays while playing hard but allow them to return when I stop playing. Thereby give the actual notes a little more space and avoiding muddiness. This does seem to be the case
However, the manual also implies that by using a negative value the delays should be louder and stronger when I play hard. This doesn't happen at all. The further to the left I turn the Ducking knob the more the delays just disappear. This doesn't seem right to me. I was wondering if others have found the same behaviour and whether this is actually intentional (if so what uses do you have for it) or a bug.
