Hi,
I’m seriously math deficient.
In my application’s preferences I have a slider that the user can set a value
from +5 down to -5, where 0 is the default and the user can then modify that.
The result is currently linear but I’m thinking that I want finer control
around the zero midpoint but coarser results at either end of the control. So
I’m needing a non-linear scale of some sort.
This is the current script. tData is a number 5 to -5. 60 was an arbitrary
number chosen to provide similar results on the two platforms (a span of 600,
which is the timescale of an audio file—I can vary the speed of time events by
1 second):
function calcBlockOffsetGlobal tData
if the machine contains "x86" then
put -300 into defaultSetting # Windows default
else
put 80 into defaultSetting # Mac default
end if
put defaultSetting + (60 * tData) into tOffset
return tOffset
end calcBlockOffsetGlobal
How would one modify this to return tOffset as a smaller change when tData is
near zero, and the opposite when tData is near the maximum?

ps. I saw a t-shirt yesterday that said “Well, another day passed and I didn't
use Algebra."
