Yeah. I'm a bit selfish in that I really like [moog~] but I'd also like to see a vanilla version to I could migrate the last of my abstractions away from externals for portability. I have tried the rjlib resonant lop~ objects which use raw filters/biquad but they don't sound as good. I only took 1 DSP course in undergrad *years* ago and my filter math is too rusty to properly understand the filters objects and the [moog~] source code.

for plotting the frequency response though, I depend that it'd be possible to emulate with biquad coefficients...

like in a vanilla patch with raw filters or biquad?
that'd be cool indeed :)

Can you make a clone of [moog~] while you're at it? :)

hi all, I've been working on filter patches for my courses and I'm still failing ti get biquad coeficients from the [vcf~] code. Maybe anyone out there could help?
I wanted this to plot the frequency response in realtime...
the [vcf~] filters aren't in the audio Audio-EQ-Cookbook, and the code looks a bit too complicated
thanks
