Variaudio 2.0 Vstl
In the old days, i.e. before variaudio and before I bought melodyne, I used to use either the pitch shift plugin or directly adjust the pitch of small clips of audio, i.e. individual notes that needed shifting, adjust the transpose coarse and fine values in the status bar. I did whole albums like that, obviously more time intensive than VA or Melo but it was the only option at the time and it can produce pro results. As I progressed I purchased Autotune and then used that as an offline processing tool to pitch shift the individual notes, or selection of notes to a specific scale. Again, more time consuming but you can get excellent results like this, perhaps better results sometimes (I like AT, I think it introduces less artifacts).
