S&S D Duplex

[Duplexdan@aol.com]

Ron,
 Just because Steinway invented the duplex scale doesn't make them impervious 
to imperfections in their tuning. It also doesn't obviate our interest in 
correcting these imperfections. By the same token it does give us, as 
technicians, an opportunity to contribute to the piano tone of their, as well 
as other instruments that purport this feature, by fine tuning them.  I would 
suggest to you that this is an opportunity to enhance the piano tone of many 
instruments rather than an opportu;nity to criticize the ir design or 
preparation.
