Plug Data LOP~ for Bass frequencies? -Solved

Hi,
it is said the lop~ filter might distort or even crash, when used for frequencies <200Hz.

So how can I do a filter for lower frequencies?
I want to do a shelving filter for Treble and Bass.

The treble side seems to work well.
Many thanks!

This issue is actually only for bp~, as it uses a biquad filter internally.
I’ll modify the docs to reflect this.

The hip~ and lop~ filters use an rpole which should have less issues like this.

Thank you! Good to know!
Although it turns out that it seems to be better to have the low cut frequency even at 250Hz…
Plugdata + Heavy is fun!
