Hi Pierre,
ah yes, Karplus-Strong, I forgot that keyword!
As for the analysis time of fiddle~, remember that computers aren't
really real-time systems ;-) Besides that, you can change the analysis
window size. Smaller windows equal faster analysis but less precision
for lower frequencies. But yes, maybe new thread....
Good luck!

Hi,
I have tried your patch called karplus-strong. This is just amazing!
This solved two problems at once : getting a sitar-like sound plus a
sympathetic strings simulation. Thank a lot!
Although i think i should open a new thread about this, i was a little
shocked by the time fiddle~ takes to output a pitch (i used it to
control a resonator with my guitar). I think it was way above 10 ms. I
haven't tried sigmund~ yet, though. Do you know what latency i should
expect? I think 5 ms should do.
Anyway, thanks again for introducing me to the Karplus-Strong model!

Thank you Derek! I'll give it a look.
Best,

Hi Pierre,
I've found resonant comb filters to be the most useful in both
simulating string sounds, and in getting sympathetic resonances.
There's tons of stuff in the list archives on them, in
particular a patch (maybe I even posted it) on calculating the
correct delay length for produce a given pitch. Search for "comb
filter".

Hello everyone,
I was wondering if anybody on this list would have an idea
of how one can simulate sympathetic strings in pd, using any
kind of audio input (especially NOT midi). I tried making a
patch with 12 resonating filters (moog~), each tuned to a
particular frequency belonging to the chromatic scale, but
the result wasn't too good (it sounded more like a weird
reverb).
My problem is basically that of isolating certain
frequencies in the input sound. I don't believe that objects
like fiddle~ or sigmund~ would be very helpful in that
matter, as they always start freaking out once you feed them
with chords.
I haven't found anything useful on the internet yet.
Any idea?
Pierre
