I have the VST3 version of Melodyne (latest update according to the software) loaded in Cubase 6.5 (latest version) on a MacPro with OS X 10.75
Several measures prior to the Melodyned vocal’s entrance there is a tempo-shift on the song’s master track (it slows down for half a measure then returns to the previous tempo). Melodyne doesn’t seem to follow this shift correctly. If I start playback prior to the tempo shift the vocal is several seconds late coming in. If I begin playback after the tempo shift everything times correctly. Whether or not I have Delay Compensation engaged makes no difference. The audio for the vocal is on the correct measure numbers within Melodyne.
I’m not sure if this is a Cubase issue or a Melodyne issue.
Please let me know what details you need to help get this fixed. I usually believe when errors like this happen it’s something I’ve done, but in this case it definitely appears to be a bug.
Thanks for your time.
