OK, if you watch that you'll have to listen carefully for the problem. But note how there are little clicks when the now time hits the clip gain nodes.
 
Things this is not:
 
- it's not to do with the steepness of the envelope; this now happens however far apart the nodes are
- it's not how it's always worked; I've been using this method in Sonar for years, and this is strictly a post Sonar 2015 problem
- it's not to do with any effects downstream; effects are in global bypass for this video.
 


The noise in your video sounds more like a click from an extremely rapid amplitude change than what I would call classic "zipper" noise. I tested this back when you first posted, and couldn't reproduce anything.
Do you still have X3 available to verify that particular project doesn't have a problem in the earlier version?
 
I just checked again, and can only reproduce a click if the amplitude changes by many dB almost instantaneously, (i.e. nodes within a couple milliseconds of each other), and no noise of any kind for anything over 4-5 milliseconds.

Yeah, Zipper Noise isn't the right term really.
 
I've just been back and checked the project in X3 and it's happening there. This is definitely a new issue for me, but doesn't appear to be down to the Sonar update. Very odd. I'm going to have to try to work out what's changed with my system in the last month or so.
