I've captured a very short recording of my issue, maybe you can help me resolving it...
Unfortunately, I did not manage to capture it with sound, but the TI only crackles if the filter-value changes (automation).
Or should I say it crackles a lot more often... sometimes, if the filter is set somewhere lower it also causes crackles here and there, but not as often as if automation is running.
Pay attention to the GUI... the knob seems to jump around. Maybe that's the reason?
