Thanks. Sure, use it anyway you want - I like the s-abstractions! If I
rememeber correctly jon~-help.pd uses 7-8 % on my aging Thinkpad T43.

I've tried to be as close to the article (page 3-4 of the pdf) as
possible with jon~. I'm working on jone~ ("jon~ extended") which has
more modulation points in the reverberation network and additional
parameters, such as bandwidth high pass. I have a GOP'ified versions
of jon~ and jone~ on the way as well. I'll post them soon.

Note that the diffusion parameters can be a bit confusing in my
jon~-help.pd patch. I think Dattorro discusses this in the article. In
my help patch the range of the diffusion parameters is 0 to 1.0. The
ideal range for decay diffusion seems to be "decay + 0.15, floor =
0.25, ceiling = 0.50" according to the article. But this, of course,
is open to experimentation.
