well, I was someone who did it, and I wonder and ask you why don't you just
use [expr~ tanh($v1)] like I also suggested. It does the same thing and is
way simpler.
I don't know about the poles and zeros from an 8 pole cheby filter with
cuttoff at 2Hz, but a filter guru would easilly find that
Thanks for the tip! Someone attached a tanh~ abstraction that basically does
what you suggested and it's working great.

Are you using mine? why not just use [expr~ tanh($v1)]?
for the cheby filter, you'd need to know where are all the poles and zeros,
then you could do it with vanilla raw filters or maybe even a few biquad~
in cascade

The tanh~.pd is working swell.
Would you all be able to suggest a replacement for the lp8_cheb~? I needed to
replace three non-vanilla items
1.) tanh~
2.) make symbol [zexy]
3.) lp8_cheb~
I am trying to convert an algorithmic patch by a gentleman named Scott Norlund
and these are the only proble
yes, you need to use a [clip~ -3 3] to restrict the input. But the
function converges to +0.99 and -0.99 or whatever by then anyway,
so for all practical purposes it is fine.

Is there something similar in Vanilla for a [lp8_cheb~ 2 100]
When I copy the iemlib abs into my extra and dive into the objects it
eventually fails because it cannot create filter~

I've never seen that approximation before but there must be some
restriction on the allowable values of X since the expression diverges
for large positive or negative values of x, while tanh(x) converges to
+1 nad -1, respectively.

there's a good approximation for tanh that can be made using just a couple
of simple arithmetic objects:
formula is: tanh(x) ~= x*(27+x*x) / (27+9*x*x)
it's close enough for every application i've ever come across, it's cheap
cos it only uses simple arithmetic, and it doesn't degrade the resolut

Using a pre-computed table for speed:

In pd Pd 0.46.6 I can do the attached patch without adding any extra externals
so it's probably vanilla.

That's tan~
tanh(x) = (e^x - e^-x)/(e^x + e^-x)
In vanilla
