|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,
check out delta from maxlib or from cxc ..
