[Frank Barknecht]->[[PD] Getting a signal's slope]->[02-08-27 11:54]
|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 ..
