Me too! I got a similar effect by using a harmonic series of resonant 
comb filters triggered by contact mike input. The mikes are attached to 
various bits and bobs I found in the Amazon... shells, plants, bones and 
other unidentifiable stuff that produce nice sounds when plucked, 
scraped or bowed. The comb filters are run through a granulating 
feedback delay that makes "clusters" of particles similar to what you 
hear on "Playthroughs" or "21:30 for Acoustic Guitar". Three or four 
delays set at irregular intervals [i.e. 3/4, 7/5, 5/9, etc] add further

Thanks! ;-)

It's not too hard, really. Particle Chamber reads from static tables, 
grabbing sections of loaded soundfiles and playing them back. I've built 
a few adaptations for myself of this idea using delay lines instead of 
tables, and they perform on input audio in the same way. I just haven't 
cleaned them up for release yet. But if you compared the "guts" of each 
patch, you would find them almost identical except for the source of the 
sound. The mechanics remain pretty much the same. Play around with that 
for a while, and I promise to clean up my own version sometime in March 
for public release.
