I would like to calculate the derivation of a curve function.

The reason is that I used it to slow down a groove playback and I need to know on which playing position the curve ends...

From your description of the situation, it seems like this will work for you?

Kind of, yes. I also thought of having an extra buffer to read from to see on which sample position the curve ends.

But I'd also would like to calculate which curve parameter I need to get in X milliseconds to a certain sample position. And therefore I'd need to set up the equation...
