Howdy, so I'm cloning the scale object from Max, to make an object and include in the cyclone library. It converts range input (low_in / high_in) to a range output (low_out / high_out). It has a logarithmic curve for rescaling according to a fifth argument/inlet. I did copy into expr the formula described in the reference of Max6/7 (max's 5 was just wrong, copied from [linedrive]) - well, it didn't work! Would anyone know if I'm doing something wrong or if the reference is not telling the truth?

The formula, as described in the reference is: (out_low + (out_high-out_low) * ( (out_high - out_low) * exp(-1 * (in_high-in_low) * log(power)) * exp(x * log(power)) ))

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...

thanks
