If I had to guess, it probably has to do with the undo tree in Melodyne not being resolved before saving. When you save in Sonar you lose the ability to undo. If you don't actually render the region you have the ability to undo, but when Sonar tries to save it probably crashes.
I'm going to guess that Studio One forces Melodyne to close the undo tree which is why you can't go back to the bounced clip.
I know people don't want to hear this, but you should render you region before saving.
Dave, you raise an interesting point, and that could well be the cause of the crashing.
I don't use Studio One, so can't test the theory, but it makes sense.
I have many Sonar projects where freezing Melodyne tracks worked just fine, but after the recent update to Melodyne 4.1, Sonar's freezing no longer works. Celemony has no rollback feature to find out if the last version has broken something, or not . . . so it seems we're waiting on Sonar + Celemony developer repairs, never knowing how important this issue is . . . in the queue ?
The workaround of simply rendering the Melodyne clips, well, it's just a workaround . . . and I want my freezing feature back working the way it was originally designed to work.
