[PD] wahwah patch

[sme]

hi yves
i think, the problem is, that the hip~ and lop~ filters do not take
signal inlets, but messages, and therefore the motion of the
cutoff-frequency sounds ugly. maybe you will like to use a vcf~ (btw, my
help-file of vcf~ was broken - i had to replace all intatoms with
floatatoms) and i think it is cheaper to use a line~ object instead of
the metro.
