Hi, does anyone know, how I could derive the slope of a signal? For example, if I have an osc~ and I want to delay the rising portion depending on the current slope of the signal, how to do this. Or more general, is there a way to get the derivative of a signal?
I tried something like "fexpr~ $x1[2]-$x1[1]" but that gave me only a stream of "0"s when printed out with print~, even if I feed it a phasor~, which never has two values the same in its signal vector, so the fexpr~ expression should never be zero.
Being a bit at loss,
