Hi there,
I'm building a sample reader and I'd like to equip it with a good filtering section, so far, I've tried a lot of pd filters and chose "lp2", but I think there must be a better sounding, more evolved unit out there. I would like to know if anyone has been working in that field... Idealy the device should be fat sounding and resonant... Any advice would be greatly appreciated!

There are at least 3 resonant or resonat sounding lowpass variants I know of:
resonant filter fom Claude Heiland http://lists.puredata.info/pipermail/pd-list/2007-11/056865.html
biquad~ + Günter Geigers lowpass external to create coefficients
e_reslop from rjlib

moog~ get used here all the time, great sound but actually dont know in which lib it is.

for filtering samples, try this: run an [env~] detector from the sample player output, and smooth it with a [line]. then use that to modulate some parameter of your filter, such as the resonance or frequency.

There are some other fat filters in rj like e_lop2 and e_lop4. They built on a pure pd implementation of GG's coefficient calculators (which are available separatly as well as "u_lowpass" etc.

imho the "nusmuk-audio"-filters posted to the list a while ago are among the best sounding (pd vanilla) filters. only the cpu-load is very high, due to fexpr~.
happy to know that you like them.
filter in nusmuk audio are biquad, but they use audio signal to change frequency so they are good if filter parametter are changing over time. they use a different structure than pd biquad so coeficient computation are not compatible with gunter objets.
the filter abstraction (that use fexpr~) can be replace with an external, so the filter can be lot's more efficient... (i don't have binary for any other platform than pd, but should be very easy to compile)
