I'm not gonna go through the paper at all anyway, I couldn't and shouldn't...
but I've just finished implementing in Pure Data a patch from that Max forum... seems to be working, but the "drum" part, as it says, it's only
"modulating the feedback so that it alternates quickly between either +1-1. different frequencies of modulation create different sounds, with high frequencies sounding a bit like a snare"
it's true, but I know you could also make some bass drum sounds, as I've seen in here https://ccrma.stanford.edu/~jos/aiff/ksdrum.aiff
what interests me, nevertheless, is learning new tricks and tweaking the values so they sound more bizarre of course.

Hi. There is a modification to the algorithm that makes it sound more like a drum. Here's a topic about it
http://cycling74.com/forums/topic/karplus-strong-extension-drum-synthesis-al...
gonna try and translate it to Pd, but wondering if anyone has ever done it already ;)
cheers

hi there, anyone knows of a drum made of karplus strong implemented in Pd?
What kind of drum? For a snare it's just a matter of choosing a low-enough frequency, then probably slapping on some reverb and other little touches to make it more interesting.
I think it's just a matter of starting with a Pd implementation of Karplus-Strong and tweaking the variables. And depending on the type of drum, you can get a lot of variety from tweaking the shape of the decay-- that is, how you attenuate the "chunk" of noise before you feed it back in.
