Thanks for the complete list!  This is very helpful.<br>
<br>
I was hoping to start off by using Vanilla-only objects.  Does anyone have some good examples of how [biquad~] can be used to replicate standard low/high/band pass filters w/ q?  Any other ideas?<br><br>~brandon<br><br><div class="gmail_quote">

Hallo,<br>
<br>
How does everyone implement basic resonant filters, ie: LPF, HPF, BPF, in Puredata?  [lop~], [hip~], and [bp~] are nice, and can easily be strung serially to create 2nd, 3rd, and 4th order filters, but lack q.<br>
<br>
[biquad~] seems up to the task, but I&#39;m unable to find any information in the help file or docs online pertaining to how one could replicate standard filters using this object.<br>
