just chipping in with my 2 cents that it would be fantastic to get more documented info on all this.
especially curious about: "but they can be combined to make other possibilities."
what sort of possibilities???

Hi Miller, still trying to get my head around this. But anyway, one thing I have to note is that the source code of [vcf~] says it is a "two pole filter", not a "one complex pole" filter.
Should that description be changed? If not, why?
thanks

Yep - vcf~ is essentially a wrapper for cpole~.

that's great to know, thanks!
Let me just see if I get a bit of the theory. Can I get [vcf~] with just one [cpole~] object and the right coeficients?
Cheers

They're quite different. bp~ is the cheapest possible bandpass filter (as far as I know). vcf~ is a one-pole complex filter whose outputs
are
the real and imaginry parts. The real part may be used as a resonant bandpass filter and the imaginary as a resonant low-pass filter, but they can be combined to make other possibilities.
It's possible to graph their frequency responses using the help patch "H10.measurement.pd' in 3.audio.examples.

Hi there, who can confirm that both [bp~] and [vcf~] are exactly the
really
same thingy? The code looks quite different...
Moreover, why the two outlets for vcf~? Help doesn't say anything.
Thanks
