The Bandpass Filter that comes with Kyma is a lowpass filter in series with a highpass filter, which means you set lowcut/hicut frequencies and if you use resonance you get two resonant peaks near the hi/low edges of the filter.

This bandpass filter is implemented by inverting an allpass filter. This means you set center frequency & bandwidth & get one resonant peak at the center of the band. It's more what I'm used to.

This might be well suited to emulating the resonant peak of an analog VCF.

Just occured to me that another way to do this is with a Filterbank/Synthetic Spectrum set to one filter only. I wonder why something like that isn't built in?
