The Highpass and Bandpass filter are not working as excepted filtering a
[noise~] signal with [hip~ 20000]. The attached images illustrating the
problem. I'm created a patch with four serial highpass filter using the same
input frequency. Until 6000Hz everything seems fine, but then things do not
work as anticipated.
The Bandpass filter is also not working. Most notably in comparision with the
[vcf~] filter.
**Using PD Vanilla version 0.45.4 does not produce any bugs.**
