What I can say after some heavy use is that DN clicking can come from a lot of things (settings lfo, amp, env, 2nd page, filter, voice settings, overlapping notes, soundlocks overlapping,…) It sucks to always search were the click comes from and that’s what I so much hate with this synth. You can have a very nice pattern 4 track but when muting suddenly a track clicks! I think it would be better if the init patch had certain settings in the off position instead of on! I never recorded yet but think this click would be a nasty spike in your wav I guess. I also have seen lots of youtube were this click appears!
I did change the way I use the synth by setting different parameters off to start with!
Even some presets comes with clicks!!!
