There is also this website 
https://www.easycalculation.com/physics/electromagnetism/biquad-calculator.php 
where you can calculate coefficients.

I'd rather use a more proper bandpass filter than bp~, which does note have a 
nice symmetric response. You could use [biquad~] instead, but the issue is that 
you'd need to generate coefficients for it. I provide the [else/bicoeff] object 
in else that calculates biquad coefficients and I just uploaded an update in my 
tutorial that shows how to do that by hand in a pd patch, see:

Tune the 3 bp~'s to a chord, and use a midi controller to set the root of the
