I mean working with scales that are different from the traditional western 12-tone equal teperament scale, as found on the piano. There are scales that split the octave differently from our tradional scale, ie quarter tones, 43 tone just intonation, 17 tone arabic scales etc.

I will try the song settings approach, that could be heading in the right direction.
