I built it for pd-ext 64bits on ubuntu current, it works well (some
crashes at exit, as you said) !<br>
Is there an easy way to make the magnitude response polygon less
"polygoney" ? If you move a strong notch filter along the spectrum,
you can actually see the line acting like a bike chain, thus
changing the visually perceived response of the filter.<br>

Announcing [filterview], a new GUI object for generating and
visualizing biquad coefficients. It allows to you manipulate
the filter band, frequency, and gain using your mouse. The
magnatude and phase are then graphed in realtime as the
parameters changed, and the list of biquad coefficients are
output. It is inspired by the [filtergraph~] object in
Max/MSP. Thanks to Mike Moser-Booth for doing all of the math
behind the scenes.<br>
<br>
It requires Pd-extended 0.43 to run. I just got to a beta
state, it works well for me, but it does crash Pd sometimes
when you close a patch with [filterview] in it. Try it out
and let me know how it works for you.<br>

Also, as a side note, this object is an experiment with a new
way of writing GUI objects. It started out as a pure Tcl
program, and the GUI part still runs as a standalone Tcl
program (try running ./filterview.tcl from the Terminal).
This makes development and debugging vastly easier.
Additionally, I tried to move more of the GUI code to the Tcl
side, so you'll see that it uses fewer widgetbehaviors, and
uses Tk's bind feature quite a bit.<br>
