Dave Porritt, Dave, Dave, Dave For your information, CFT Steinway;s first pianos with duplex scales DID HAVE individual oliquots. I have an opinion as to why he developed the contiguous harmonic bridge but that is an opinion only. As to your inference that the duplex was developed as a marketing ploy a deeply grieved . That you are suggesting that Hermann Helmholtz, the greatest physicist of the world, in his time, and CFT Steinway the greatest inventor of piano design features collaborated in a marketing ploy belittles our profession, and is not worthy of your dedication to our profession. It is also an insult to the scale designers of countless other pianos who have integrated this feature into their instruments. May I suggest you rethink this point of view. Duplexdan
