Hi

I waste an awful amount of time doing input scaling maths, with only basic maths chops. The scale object isn’t flexible enough to allow me to do the following, without a serious amount of trial and error (usually tweaking the exponent, or faffing around with [expr]):

0. –> N/2 –> N

0. –> X –> Y

for example 0. –> 0.5 –> 1. outputs 0. –> 100 –> 1000.

Is there a simple formula which would allow me to define N, X and Y? This would save a vast amount of time trawling the forum and reposting essentially the same question for different values.

Many thanks

(preemptive hanging head in shame)
