I never tune to a scale either but here is some information on it.

" The world of scales and tunings

Melodyne allows you to work with whatever scales and tunings you like, including exotic or experimental ones. Unusual scale structures and irregular tuning are often important musical parameters that ought not to be ironed out. For this reason, Melodyne supports every conceivable scale or tuning system, allowing you to handle the nuances of each musical genre with sensitivity.
You can also define and edit scales and tuning systems, as well as analyze those found in existing audio material."
