A possible extension to non-12-EDO scales

Hi folks.

I'm not sure what this is but I actually don't think it's that "automatic pitch correction" effect (because of the tiny pitched echoes which do not occur in these "Autotune-like" things). Sometimes it sounds like a vocalizer controlled by MIDI notes or whatever, sometimes it sounds like a speech synthesizer with given intonation, I'm really not sure. But extending this to non-12-EDO scales may offer interesting possibilities:
