Hello, list.
Do you know what the difference equations of [lop~] and [hip~] are?
Just hoping that one of you has a quick answer, otherwise I'll try figuring it out by looking at the code.
Anyway, they don't seem to be the same as [rpole~] as the impulse response is different.
Thanks, Dario
Hey Dario,
[lop~] can be implemented with just an [rpole~], did you make sure to set the coefficients correctly? I've attached an example patch to implement [lop~].
[hip~] is an [rpole~] and [rzero~] in series. You can find the coefficients in the source code.
Cheers, Joe

let me share some patches too.
as said: lop~ is not the same as rpole~ but is possible to be implemented using rpole~, hip~ can be implemented with rpole~ and rzero~
my patches show the difference equations and all, they're in portuguese, and part of my computer music class examples available here https://sites.google.com/site/porres/Live%20Electronics%20%28EL%20Locus%20Solus%29%20-%20Porres.zip?attredirects=0&d=1

Thank you so much for your answer, Joe and Alexandre.
You're right, Joe. I was actually referring to hip~ when talking about the impulse response, indeed hip~ is one-pole and one-zero. It might be good to specify it in the help file.
What formula would you use for the coefficients of rpole~ and rzero~ to implement it?
Cheers, Dario

it's on one of the patches I sent ;)
These should be the coefficients for implementing hip~ with rpole~ and rzero~
Fc - cutoff frequency Fs - sampling frequency
a = 1 - (Fc * 2 * pi / Fs) // 0 <= a <= 1 b = (a + 1) / 2
w[n] = x[n] + a[n] * w[n-1]
y[n] = b[n] * (w[n] - x[n-1])
