hi, epxr~ (which is vanilla) has a tanh function. I updated the expr help file to include all its functions for the 0.48-0 release, in case people missed it.

so an easy vanilla tanh~ implementation can just be: [expr~ tanh($v1)]

cheers

Hi, i want to implement the tanh function in PD Vanilla. I use the formula y(x) = (1 - b*e^-(a*x + lnb))/(1/b + e^-(a*x + lnb)) where (a) is a steepness parameter and b controls the amplitude range. You can see my implementation which seems to work, but when I incorporate it to larger patches, I get a core dumped...

Any clue why is this happening or any suggestions for a better implementation?

Thanks,

Kosmas
