      I think it's related to this issue I had - https://forum.hise.audio/topic/1149/how-to-add-lag-to-a-knob

        Yeah, just don't use the Moog filter it's crap.

          @d-healey - hmm lag - maybe if there was some sensible way to add that in, but (and I dont want to be some sort of dram queen here) its pretty fundamental that instruments can have filters that are modulated.

          @Christoph-Hart - any idea how to get filters to work here?

            @Christoph-Hart - as are all the other low pass filters - as they all do the same thing to some extent.

              Check my snippet there are no artefacts there.

              If you're using an envelope make sure that the attack times are not too fast or it will click.

                @Christoph-Hart - yeah exactly - I need to use an envelope - I did check your snippet - nice - but not what I need. Still as you say its better - but still not right. I will replace all the moog filters with the ladder - but I'm still getting artifacts out of it and the other low pass filters with my audio.

                    But give it some audio material like a sine wave and back they come.

                        Well, if you're using the sine wave generator with the unisono feature, you'll start with a click because of the random phase offset which might get amplified if you run a fast envelope with a high Q filter over it, but this is the only artifact I hear...

                          @Christoph-Hart yeah I can see that - however when I run a sampler through it with "complex" audio there are still artifacts... but let me do a bit more testing and see if I can track it down

                            @Lindon OK well its a LOT better using the Ladder filter - the Moog is, as has been mentioned, really not worth the time. "Complex" audio can at times expose the limitations in the filters(more than one of them) but I can live with it.

                            It just leaves me wondering about the filters in Kontakt - which exhibit none of these problems. My knowledge of filter design is limited to say the least - but my mental model says its all about working out the coefficients and applying them - so I cant see why NI's filters seem much more "friendly" - but as I say I'm no filter designer...
