Dear MAX/MSP-masters,

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...

Thanks in advance,
ring

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...

thanks!
