Herb,
With all due respect, you are dismissing my remarks without knowing what I am talking about. Eg., Melodyne Bridge is a part of Studio or Cre8. Because you get the manual for Melodyne Editor with those two, the first things a DAW user needs to know to use Melodyne is not explained, which is rather glaring. The Undo issue us a known UI problem of the plugin. Etc. As far as tinny quality, if you never heard of it, here is a comparison I did a while ago using quick 1 bar vocal samples. The sample plays first untransposed, then Melodyned, then Abletoned, then TC Heliconed (then the next group follows)
Vocal comparison (14 MB wav)First group is male vocal at -6semitones, next group is male vocal at +6 semitones, next is female vocal at -6 semitones, next female +6 semitones. Extreme transposing, yes, but that's where quality differences really come out. Melodyne at its best setting produced only second best results after Ableton. HTH.
