I noticed this recently, too. Seems to be more prevalent as the filter is closed, starting at around 50%. With all oscillator sliders at 0%, playing a sequence or arp is very clicky and it almost reminds me of the Minilogue's clicking envelopes. Playing with the AD sliders I can make it less noticeable but it definitely feels like something isn't working as intended and I don't recall it being an issue before.
