Question about Pyramid Delay F/X


#1

The Delay section of the manual says:
GAIN 0% … 200% _
** Change the MIDI velocity of each delay note. The velocity of the delay notes will be gradually decreased (gain > 100%) or increased (gain < 100%). If the gain is set to 100% velocity will not change.**

Maybe a silly question but why is that ? Why a gain >100% makes repeats decreasing, and a gain < 100% makes them increase ?
