The scales available with the Diatonic and Quadravox algorithms in the most recent Pitchfactor software include the following:

[MAJ] – Major
[min] – Minor
[DOR] – Dorian
[PHRG] – Phrygian
[LYD] – Lydian
[MLYD] – Mixolydian
[LOC] – Locrian
[Hmin] – Harmonic Minor
[Mmin] – Melodic Minor
[Wton] – Whole Tone
[ENIG] – Enigmatic
[NPLT] – Neopolitan
[HUNG] – Hungarian

No idea if there are plans to add more or not.

By the way, can anybody recommend some reading material (preferably a book) on the historical use and development of scales? I wasn't aware of the Wendy Carlos or Pythagorean scale before and they're absolutely fascinating. I'd love to read how ideas for scales and modes developed over time.
