Well, maybe not. Two unisons, Wapinized, alternating with two unisons, repinned (etc.) as usual, should give you a fairly decent idea of the difference in any part of the scale within one piano. It seems to me that, if the difference was so dramatically and obviously wonderful, the folks licensing the process would have one made up like this and haul it to every seminar and convention there is to show it off. Then again, there's the hammer voicing, which can shade things in the direction the voicer wishes, so there probably isn't any realistic way to make a determination. Oh well, there's always magic varnish. Ron N
