The bandpass and highpass filters have some weird artefacts when at max frequency (20k)
In theory you should not hear much - but there is some weird elements coming through that you would not expect to hear. (Thumps and clicks from a kick drum etc)
While not as apparent - the low pass still lets through clicks from truncation of samples etc - these clicks have a high freq content element to them - but I’d expect the filter to roll this off -especially when Lowpass is set at 20Hz.
I’ve seen this as well. I llike to set a bandpass to filter out everything but the bassline on a sample so I can turn activate the filter after x number of patterns to just hear the bass. With it on I notice some high crackles and pops and even if they do exist in the sample shouldn’t be coming through where my eq band is set.
