Hello Philip J Ryan You said:"Seriously though, I can envision a battery-powered tuning hammer that would nudge forward and/or backward just a trifle when a trigger is pulled. Is such a thing feasible? Or am I being pollyannaish? How about interfacing this with a ETD? Maybe to a Clapper device? (Grin) Any thoughts?" I made a comment early on in this post that I understood Yamaha to have a power tuner which turns all the pins at one go. This is in order to equalise the tension across the plate etc. as the piano is being brought up to pitch for the very first time.... (I don't think I would like to be within hearing distance when that noise is going on! ;-) Regards Michael G (UK) nearly News Time in the heart of the South Downs
