I’m using Melodyne the old-fashioned way (not ARA) to correct the pitch on some bass notes. Examining the notes in Melodyne before making changes I can see that their pitches vary from slightly sharp to slightly flat by about -1 to + 14 cents so I set them all to 0, so completely in tune.
I then use Render In Place using the ‘Channel Settings’ option which, as I understand it, should include any active inserts into the rendered file (Melodyne is an active insert but all other inserts on the track are disabled for this process).
If I then load an instance of Melodyne on to the newly rendered track and transfer the same notes to it I would expect the pitches of the bass notes to still be at 0 cents (perfectly in tune), but they now show with completely random pitch differences.
This seems like a bug to me.
