I have it on good authority that professional synthesizers can do this, realigning the whole keyboard pretty much any way you want. Unfortunately the current Kawai 'stage piano' will not do it, because it isn't a full synth, just a good digital keyboard with midi controller functions. The more consumer oriented things will allow tuning one octave pretty much any way you want, but every octave is then set to the same - so the 'C's would all be correct, and then you'd have 1/2 octave of notes up until the next C, etc. Notes C - f+ (F plus 1/4 tone) would be there, but F# - b+ would not. Hope this helps. Don Mannino
