I think I have a very simple argument here, proving the op incorrect.

I don't know anything about c++, or coding computer software, but what are you saying Mr. Robin? There is a fundamental algorithm that parametric eq's share? That is what I think you are saying, that is what I think the OP is saying.

Let us chew on this concept--

Are all airplanes, cars, trains, lasers, surgical instruments, buildings, bridges and etc, the same? All of them share some fundamental concepts. Actually, everything on earth seems to share concepts.

I'm sorry, but to build a bridge you follow some very stringent mathematical formulas. Perhaps the same is for parametric eq's. I fail to see how all bridges are the same.

That said, " All eq's are exactly the same, except for X." Is a pretty weak argument. IMHO...

Even if it is slight difference in the distortion and q....

Well, What about the slight differences between a bullet, and a missile?
