Hi, I just discovered this, wasn't sure how to report it so I hope this is the right place.
To reproduce the bug:
Solo a partial in the SCR mode, and make sure it has two frame (time slice) points. Click on the second one.
Draw in a variety of different phases for the modulator's harmonics, using the graph at bottom right. Important: make some of them are at maximum value.
Click on the initial frame point.
Click again on the second frame point. You'll see that all the phases that were set to maximum are now set to minimum!
As a developer, this feels to me like an 'unsigned int' sort of error. In other words, someone has misinterpreted (e.g.) +128 as -127...
Hope that helps. Let me know if you need images as I did take screen grabs. Also, let me know if I should be reporting this elsewhere.
Thanks!
