Although interesting as a technical engineering concept, it's really more of a marketing curiosity than something that's genuinely useful. (Much the same could be said of the sostenuto on grands also! - there's so little music written that requires its use). That middle pedal on uprights is much better served by being the controller for a well-designed felt muting rail, such as in the Yamaha U1. Not necessarily "bad/dumb". But when out of regulation, can be a real time-sink, adding additional expense to a customer's bill for something that has such limited use. ----- Original Message ----- From: "Farrell" <mfarrel2@tampabay.rr.com> To: <pianotech@ptg.org> Sent: Thursday, October 11, 2001 8:59 PM Subject: Re: Trivia > I have not serviced a sostenuto on an upright, and being that I don't play, > I don't have any experience from the pianist standpoint.
