the object you describe sounds to me identical to [maxlib/scale]

it almost is, but in maxlib you just turn the mapping to log on or off, in max you specify a log parameter.

I did share a patch in text and attached. Not sure if everyone gets the attachment so I sent the text file as well, but here's the attached file to you again, and I'm also sharing a downloadable link

by the way, I'm pretty sure I'm not doing anything wrong, and the given equation in Max just seems to be wrong

cheers

Here's my patch with that formula into expr. The output with the parameters I have should be -0.997347 - as that's the output I get in Max. But instead, it's giving -0.994694...

Would you care to share your parameters so we can test your abstraction?

Also, I haven't been reading this list very attentively lately (busy days, you know) so I may have lost quite a lot of discussions lately, but the object you describe sounds to me identical to [maxlib/scale], which takes 5 arguments: input low, input high, output low, output high, coefficient (linear or log).

Cheers, Gilberto
