Sorry, I quoted wrong so didn´t make my point clear… I was rather refering to
The problem i’m facing with all that in mind is how to limit a point on the canvas, it sometimes need to be dependant on other points and sometime it needs to move freely around.
. And that also in connection with his statement that a sequence of typed points would be a no-go… The EQ envelopes are the only ones I could imagine where each point can really move freely without any sequential dependency.
You are right about the rectangular regions. They are therem, whether you paint them or not. They define the bounds a point can move within. And even if you leave points aside and think resizeable rectangles, the changellenge is the same.
