Hello, I don't know if it helps, in ggee there are filter objects
that are applying formula for biquad coefficients, it's easy to use
those formula in expr and apply them to biquad object in vanilla.<br>

<div>I know of patches that can plot from biquad coefficients,
so it'd be great if I could get biquad coefficients from an
input of frequency and Q.</div>
<div><br>
</div>
<div>I see [bp~] is a 2 pole filter. So does it mean I can
achieve it by zeroing out a bandpass filter made with
[biquad~]? Cause I see people make bandpass filters with
2poles in biquad, but the zeros are at -1 and 1. I tried zero
values of zero, but it didn't look to good to make me believe
that's the same as [bp~].</div>

<div>I know of miller's example H10.measurement.pd, and compared
to it, didn't seem to fit.</div>
<div><br>
</div>
<div>Anyway, I wanted something that would plot [bp~] right
away, not like the H10 example, which takes some time. But
then, if we can't do it with biquad coefficients, I would need
some guidelines to do it some other how.</div>

<div>Thanks</div>

<div>Cheers</div>

<div>I know about filterview and patch</div>
