Evenitde has a beta update out now for it's Pitchfactor product (owners of Eventide pedals download these upgrades). Eventide has had a nice harmonizer on it's Pitchfactor pedal, with a learn feature that figures out what key you are playing in, but it had been limited to the basic modal (Major, Minor, etc) scales. One of the nice enhancements has been the addition of a number of other scales, such as harmonic minor, Hungarian, and 4 others.
But I believe there is a problem with the Melodic Minor scale in the harmonizer. Of course a beta is put out there to get feedback so they can correct errors and bugs, and I reported this one. But I am not positive that it is an error, only a person adept in music theory can give me the definitive answer. Can anyone give me that answer? My post to Eventide follows.

This concerns the Melodic Minor. Now let me say first that I am thrilled that the new scales were put in, particularly Harmonic Minor. However it seems that the Melodic Minor is not setting the harmony note correctly for a higher third harmony for one note on that scale.
Let me express myself by example, in the key of C Melodic Minor. For the Bb note (descending), a third is harmonized in the Pitchfactor with C# (or Db, however you want to look at it), i.e. as a minor third above Bb. But Bb is not even in the Melodic Minor scale! I would think that a major third would be appropriate as the higher third harmony note here, i.e. using D.
Perhaps for centuries this is how that note has been harmonized, using a note outside the actual scale, perhaps I am ignorant of that fact, and someone will enlighten me. However I doubt it, I think this is probably a glitch.
