I have found that melodyne 5.1.0 in cubase 11 (using ARA extension) seems to randomly lose any edits made after a high number of saves OR a save as project. I need to narrow it down a little more but wanted to flag it to see if anyone else has noticed. The only workaround seems to be to do edits and then bounce or render the audio before closing down.
I’ll investigate this more but I am mid project at the moment. This problem doesn’t seem to be occurring in Cubase 10.5.
My hunch is that all the edits are lost if you do a ‘save as’ project and rename/append a character - somehow the ARA link is lost. Going back to an earlier file doesn’t seem to fix this completely for me (its almost as if the data is lost in certain random audio parts)
EDIT: On reflection i have had a few crashes during this process. Could it be that when cubase notifies you that there is a backup file newer than the .cpr and it creates a new project it leaves off the melodyne data that this is where the issue is actually coming from??
Edit 2: melodyne is causing an occasional crash. I have a crash DMP file if anyone would like a look?
