> the pads can be retuned to different scales suggesting a complete break from any kind of equal temperament octaves.
I was kind of curious about this since in the medieval era, equal temperament wasn't used very much. But it just allows retuning to major/minor and modes in equal temperament, as far as I can tell. Would be an excellent device for medieval music if it could be tuned to meantone, Pythagorean and so on!
