Hi Frank. Sorry about the accidental posting to pianotech. That said I'd have to agree with your assessment that duplexers not inconsequential. As to what one prefers or doesn't... well to each his own as far as I am concerned. I tend to like piano that have them... with few exceptions. I doubt your position is an unpopular one to take since all but a handful of the piano builders / designers I've met opt for them. I think its fair to say however that the use of vertical hitch pins without duplexers can be successfully used in piano design as well. Curious as too your objection to vertical hitch pins. Personally I dont see the big deal either way... Cheers RicB I guess there is a parallel thread with CAUT that I have not seen. I would have to disagree with the notion that duplexers are of no consequence. I have designed and built pianos with and without vertical hitch pins. At this point in my experience, I have no use for vertical hitch pins and do prefer a duplexer style of construction. I suppose that is an unpopular position to take, but it is mine. Frank Emerson
