vcf~ isn't a 2-pole real filter but a 1-pole complex one
kinda relative to this, since biquad~ can be emulated with 2 complex poles
- 2 complex zeros
it can not only be emulated, it can be implemented with a complex 2-pole/2-zero filter.
, is it more accurate to say biquad is a 2-complex_pole-2-complex_zero-filter???
no. it's accurate to say that [biquad~] is a real-valued 2-pole/2-zero filter.
real values are a subset of complex values (with the imaginary part set to 0).
In its description it says it is a 2-pole-2-zero-filter...
which is true.
