Quick Question: What's the formula for the envelope curve (with tension) in REAPER?

[RCJacH]

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?

REAPER uses a Bézier curve, not a power curve, but I don't know how neighboring points affect the curve: Formula for Bézier curves (question for the devs).

Oh, so is this the reason why this is happening ?

If so, too bad because it's not a desired behaviour.
