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. marius.

hi,

i've been trying to make a patch which produces a wah-wah effect, as the theory says, it moves a peak frequency in a bandpass filter, but i'm not too satisfied with the result.

my questions are :

a/ did someone already did this ( in a better way ) ??

b/ if not, how could my patch be improved ?? ( i guess i must add a saturation of some sort )

c/ anyone modelized saturation ? ??

cheers,

yves.
