I've tried to build a distortion just using some parametric filters for boost the input signal,and than a clipper..
..but the results are not so good..
do you have some suggestions?

I havent find any good distortion algorithms on the web..

leonarrdo-

Now it's your turn to shed some more light on what you're doing i guess

nestor, what did you use for sending to the indexed table? osc~? your inlet~?

Will post when I get off work.

Try this.

Not bad

is there an attachment I can't see? (I'm logged in)

Yeah. I'm not seeing the attachment either.

Hmm, I don't seen to recall..... I'll poke around in some folders.

Edit: Something like this maybe? Load 2 loops....

FYI,
I've been playing with the technique posted by domien for a guitar amp simulator effect. I used a much smaller table (12) and tabread4~. This is much easier to fine tune. Follow it with some EQ and freeverb~ and it sounds as good as any other amp simulator I've used.

dack, do you want to share waveshape arrays? here's my favourite:

-0.928551
0.942857
0.942857
-0.328557
-0.0571318
-0.12856
-0.328557
-0.442842
-0.614269
-0.614269
-0.542841
-0.314272

definitely doesn't sound as good as any other amp simulator I've used though!!

posted some other distortions at:

I took arif's waveshape array and made it time dependent (with attack and release settings). It's just an example and could be made better.

Should be a little closer to an amp simulator.
