This might be really basic. I'm trying to look for tension formula for tension of a linear line curve for envelopes in jsfx.
The common linear curve is distance/range, and I used (distance/range)^power to add tension.
However, the linear curve in REAPER looks a bit different:
Reaper Linear:
Max tension:
Min tension:
While with the linear ^ power:
Max tension:
Min tension (which looks weird):
Thus my question is, what would be the formula to create a curve with tension which is used for envelopes in REAPER?
