Guys, i have this problem big time. If i touch the knob or push it harder the qlinks work but if i just turn them slightly it doesnt work at all. This makes automation a mess. I'm thinking about claiming warranty. Anyone else have still have this problem? Does it work fine for most people? I kinda wanna check if this is still a software error or whatever (seems to go away if you take the caps off).

What I notice is if I stop my sequence than I get full control in Sample Edit. Sometimes when playing another sequence it can get laggy or just "stuck" for a moment. So now my workflow is to stop before editing when I need to chop in depth.

Seems software related.. It's definitely not mechanical in my case, because the same knob works fine in certain menus, doing certain things.. Then when trying to automate the cutoff for the filter of some plugin synth and it lags like crazy.

It seems to be a bit random..

I initially thought for a while that maybe there's too much going on and the CPU struggles or something.. But pretty sure this can happen in relatively freshly started projects and not much going on..

And there's times where a lot of stuff is going on, and it automates stuff just fine..

Also pretty sure this was not a problem when automating plugins in the beginning, but arrived with later updates, although I may just have been lucky then.
