generate harmony voices then edit pitch

Can anyone help me? Cubase 7.5. Have generated harmony voices but want to edit using sample editor to change pitch of some notes. I drag the notes to where I want them but they jump right back. On the main vocal track my changes apply. Is there a trick?

Thanks.

I am guessing that the harmony voices are still being determined by the Chord Track. I think all you need to do is, for each of the newly-created audio tracks, set “Follow Chord Track” to “Off”.

Many thanks. That was exactly the problem - now sorted.
