Everyone else @here, thanks for all your feedback about the clicking/popping issues.
As written in my previous comment, 1.7 release brought considerable “improvements in regards to the issues logged here”. As our guidelines say, we shouldn’t log multiple problems under one bug report as it becomes harder to understand, track and eventually fix them. Since this is a complex topic and we solved most of the clicking issues, we’ll allow an exception in this case 
But I believe all remaining issues could be phrased as:
- Audio clicks when sample is interrupted by another one on same track or when using CUT / FAD
So, I suggest we close this topic and log this one as separate remaining issue, along with any other which could still be happening (possibly the one from my previous comment).
Thanks again for all of your support!
