Click on picture to enlarge and see the Melodyne analysis of the unknown tuning.
By using stacked keyboard note to frequency settings in the Parva modulation matrix I happened on this tuning that has a very nice sounding 318 cent near just minor third and a 1470 cent “9th” interval. This -almost- closes at the octave + tritone – which is close enough that Melodydne doesn’t show the octave with the default settings thinking it is an overtone.

This re-tuning technique relies on changing the midi note to pitch relationship called in some circles the “slope” of the keyboard.
