How to change linear A,B modulation behaviour into customized behaviour

guess i should call it all: "domomo’s how to threads" from now on

what i wish to do:
for now, the modulation of A, B reacts linear of course.
let’s say its linearity is simply from 0-1

but for some reasons (particular approach) i wish to add a switch to change this behaviour into something like e.g.:

0 is at normal 0 state (but : )
0.5 is at state 1 (and : )
1 is at state 0

to keep it simple for now. because easy explanations are always striking
the described behaviour would act like a simple triangle curve so. (yes, i might search for a little more complex curve behaviour later on, but for now this is fine)

Primary control shaper , here is some more info if you want to do it in core

that's exactly what i was looking for tyvm!
if anyone interested ... and to show my entire gratitude, i built an "9 break point control shaper" out of the meantioned/uploaded core implementation:
