ok, thanks

I haven't quite understood yet so I'll see later but I already have another question :
what if the functions are some signal functions . For instance, instead of being
(subtract 1) :: a -> a, 
it is a signal 
func :: Signal (a ->a) ?

Is there also a simple way to compose func with an (x :: Signal a) in order to produce a new  signal ?

I naively tried 
y=func <*> x 
but the influence of func doesn't seem to exceed a frame.
