this is because [pipe] is similar to [pack]: you have to specify the 
type on object creation and the types are then fixed.
e.g. [pipe f s 100] can only be used for lists consisting of one float 
number followed by one symbol, with a delay of 100ms.
[pipe] is synonymous to [pipe f 0] (0ms delay of 1 floatingpoint number)
banging the [pipe] object will therefore convert the "bang" to a default 
number "0".
is you bang a [pipe s 0], you will get a default symbol "symbol".

if you want to delay bangs, use [delay], or [select] the number output 
by [pipe] into a bang.
